The Principle of Resistance Welding
Fine Spot Welder System Configuration
Resistance welding is a thermo-electric process where heat is generated at the interface of the parts to be joined by passing an
electrical current through them for a precisely controlled time and under a controlled pressure (also called force).
Since only a low voltage (several volts) is applied in this welding method, there is no danger of electrical shock to the operators.
In addition, resistance spot welding generates only small amounts of fumes and does not emit bright light, so the work
environment can be kept safe. Resistance welding is used for many automation systems because it offers consistent quality,
good cost-performance, simple operations and easy maintenance, thereby contributing to labor reductions.

Direct welding
Indirect welding
Layered workpieces are held in
place by electrodes, and welding
current is directly applied from
one electrode to the welding
part; this current flows to the
other electrode. This is the basic
method of resistance welding.
In this method, two welding
electrodes are placed in contact
with separate workpieces, and
welding current applied to one
electrode passes through the
welding part and flows to the
other electrode, which is located
away from the welding part.

A controller to input the welding schedule and other information.
Welding transformer*2
Converts the current output from the welding power supply into the high current required for resistance welding.

In this method, two welding
electrodes are placed in contact
with the same workpiece.
Roller- (disc-) type electrodes
hold the workpiece in place by its
top and bottom surface and rotate
as they apply force and current to
continuously weld the workpiece.
This method is best suited for
continuous welding of long
workpieces.
Displacement sensor
Measures displacement (amount of weld penetration).
Electric force sensor
This sensor can simultaneously measure both the welding current and force applied between the electrodes.
Force sensor
Measures the welding force applied between the electrodes.
This welding current and force application system allows the electrodes to come into contact with and apply
force to the workpieces and then applies a welding current. There are two types of weld heads: pneumatic
and servomotor-driven types.

Parallel-gap welding
Projection welding
Welding is performed with a narrow gap
between two electrodes. This method
uses the same principle as series
welding. However, parallel-gap welding
is used for creating a single weld joint
between electrodes instead of two weld
joints, as in series welding. This method
is effective for welding narrow sections.
A focused high current is applied
to a projection provided for the
workpiece. By providing
workpieces with different plate
thicknesses with projections, this
method allows workpiece
temperature distribution to be
balanced.
Sets the height of the electrodes and vertical motion speed of the force follow-up mechanism.
Force follow-up mechanism*
This mechanism enables the electrodes to apply a stable welding force as they follow-up the spring load.
Electrodes
Chromium copper is usually used as the material for electrodes because electrodes must have superior
electrical conductivity and be unlikely to be deformed under high temperatures. By contrast, tungsten or
molybdenum is used to weld materials with low intrinsic resistance (copper, aluminum, etc.)

Features of Each Type of Welding Power Supply
■Transistor-type welding power supplies
What is Fusing?
■DC inverter-type welding power supplies
Due to their high-speed current control, transistor welding power supplies
can be used for fine, precision welding. They can accurately control high
currants by means of transistors, Thereby reducing weld splash. They are
suited for projection welding, which Is essential for short-period,
high-welding-currant application, as well as welding of thin wires when
deformation of workplaces due to welding Is undesirable.
DC inverter welding power supplies do not have a blank period in the currant
waveform, unlike AC-type power supplies, so DC inverter-type supplies can
allow current to flow continuously, resulting in high thermal efficiency and short
welding times. Therefore, thermal effects are less and welding can be
accomplished with minimal power consumption. In addition, this type of fast
feedback control ensures stable welding quality because the splash effect does
not easily occur. Thus, it enables fine, precision welding. Since a more
compact transformer can be used compared to AC-type power supplies, the
DC inverter-type can easily be mounted on automation machinery.
■AC inverter-type welding power supplies
No need to buy new weld head and transformer if you already using AC
welder for production. Able to have higher precision and higher resolution
current control than AC-type welding power supplies, and welding with high
thermal efficiency is possible.
If the flow of the current is in one direction like the DC inverter-type welding
power supplies, a magnetic field is generated around the welding current
and the surrounding magnetic material is magnetized, or heat is biased to
one electrode in welding of dissimilar metals (Peltier effect) may occur.
AC-type inverter welding power supply reduces magnetic material around
welding current being magnetized. It also suppresses the Peltier effect,
slant abrasion of electrode and unequal size of welding nugget.
■Single-phase AC-type welding power supplies
Single-phase AC welding power supplies are basic welding power supplies
that control AC currant conduction angles. However, they do not have good
thermal efficiency and workpiece& are likely to suffer thermal effects, so
this type is not suitable for precision welding.
lnstead,this type is often used for iron materials for which welding can be
performed relatively easily.

Capacitor welding power supplies charge a capacitor bank, which is then
discharged to release a high currant at once. They are suited for welding
low-intrinsic-resistance, high-thermal-conductivity materials, such as
aluminum and copper. As they can charge capacitors at any voltage,
welding can be performed stably even when supplied voltage fluctuates.

While applying current to the workpiece, the interruption function interrupts the application of current upon
reaching the amount of displacement that has been specified in advance even if in the middle
of applying current; at this time, welding advances to the next step.
This prevents deformation of workpieces due to excessive welding currents, resulting in stable quality.
This function is available for welding power supplies, the MM-400A weld checker, and displacement sensors
that support interruption functionality.

Control system
Feature
Purpose
Control mechanism
Primary
constant-current
effective-value control
No need to connect a toroidal coil to the
transformer ’s secondary side. The inverter
transformer’s turns ratio must be set. Transformer
loss is not considered.
Used for robot welding or other welding
performed in an environment where the
toroidal coil and its cable tend to become
disconnected due to the movement of the
weld head.
This system controls pulse width by obtaining the measurement
current by detecting the primary current using the current sensor
installed in the power supply, and then ensuring the difference between
the calculated values for each control frequency and the primary
current (obtained by the formula: Set current / turns ratio) will be zero.
Secondary
constant-current
effective-value control
The welding current is controlled by directly
detecting it; thus, current accuracy is higher than
that of primary constant-current effective-value
control.
This is commonly used in general welding
applications.
This system controls pulse width by obtaining the measurement
current by detecting the welding current with the toroidal coil, and
then ensuring the difference between the calculated values for
each control frequency and the set current will be zero.
Secondary
constant-power
effective-value control
Since the power between the electrodes is
controlled to be consistent, input heat is
consistent, thereby addressing changes in the
statuses of workpieces during welding.
Used when expulsion occurs as welding current
starts flowing and must be reduced, when a shunt
current is generated during welding, or when heat
generation during welding must be constant.
This system controls pulse width by obtaining the power based on the
measurement current obtained by detecting the welding current with the
toroidal coil, and then ensuring the difference between the calculated
values for each control frequency and the set current will be zero.
Primary
constant-current
peak-value control
Although the transformer’s turns ratio must be set, there is no
need to connect a toroidal coil to the transformer’s secondary
side. Although transformer loss is not considered, increase in
current is faster than that of effective-value control. This
system is therefore suited for short-period welding.
Used for welding plated metals or different
kinds of metals.
This system controls pulse width such that when the primary
current (detected by the current sensor installed in the
power supply) reaches the current limit set as the primary
current obtained from the set current and transformer’s turns
ratio, switching will be turned off.
Secondary
constant-voltage
effective-value control
Pulse width is controlled by the voltage between
the electrodes, which enables welding with less
splashing by controlling the initial voltage to be
constant while lowering the current.
Used to restrict expulsion when welding materials
with high intrinsic resistance, welding cross wires
and other workpieces with high contact resistance,
and welding projections with high resistance
fluctuations at the start of welding, etc.
This system controls pulse width by obtaining the
measurement voltage by detecting the voltage between the
electrodes with a voltage sensor cable, and then ensuring
that the difference between the calculated values for each
control frequency and the set voltage will be zero.
Welding is performed at a fixed pulse width. This
is not feedback control.
Used only for special occasions such as
when inspecting welder capacities; not used
for general welding purposes.
Performs switching control at the set pulse width.
Used for welding cross wires or other cases
where the contact area is small at the start of
welding.
This system controls pulse width by comparing the voltage
between electrodes with the set voltage as well as
comparing the welding current and set current; one or both
of these are controlled so as not to exceed the set values.
Welding is performed while detecting the welding
current and voltage between electrodes.
Figure 1
In the case of series welding, such as tab welding for batteries, current flows in one
direction (standard type) as shown in Figure 1, which generates heat on only one
electrode due to the Peltier effect (polarity switching). This causes uneven nugget
diameters on the positive and negative sides as well as places significant wear on the
electrodes. On the other hand, with the alternating polarity type shown in Figure 2,
current flowing in both directions (positive and negative) enables nearly uniform
nuggets to be formed.

We recommend use of a weld checker, which allows parameters of
multiple decisive factors for weld quality to be measured simultaneously,
in order to consistently achieve stable weld quality. In addition to
measuring active parameters, weld checkers can also output an NG signal
and evaluate welding performance if parameters deviate from their
specified ranges.
Multi-cycle current supply/single-cycle current supply/half-cycle current supply
Welding current supply system
AC timers
In order to achieve consistently stable weld quality, these seven factors
must be periodically confirmed one-by-one. However, welding current,
welding time, and force cannot be observed visually. Thus, measurement
and monitoring with the aid of a weld checker are necessary to
appropriately manage these three factors. For fusing operations,
appropriate management of displacement is also important.

Features
● Compatible with mass production automatic machines

Weld head roles
● Suitable for a wide variety of welding
What is follow-up force?
With the aid of electrodes, weld heads play the following roles.
❶ Application of force to workpieces
❷ Application of welding current
❸ Heat removal (cooling of workpieces after weld pulse by absorbing heat
generated in the workpieces)
❹ Forging (adjustment of the shapes of the workpieces of welding by
pressing against the workpieces)
❺ Heat balance
❻ Follow up force on the expansion or contraction (due to heat) of workpieces
In addition to welding current and welding time, force is a critical control
factor in resistance welding.
Heat generation during welding varies depending on the contact
resistance of the electrode and the workpiece.
The Current Application Methods and the optimum welding force can be selected by
combining with the follow-up mechanisms *1
Follow-up force refers to constantly applying a stable
force during welding to quickly respond to the expansion
or contraction of the workpiece. Poor follow-up force
leads to splashing, excessive surface pressure marks,
and a poor weld. Although the magnitude of fluctuation is
small, since the plate thickness of the workpiece
fluctuates over a very short period of time during welding,
follow-up force becomes a critical factor. Follow-up force
can be improved by reducing sliding friction when the
mass of the movable portion is reduced. AMADA
MIYACHI’s weld heads have been designed to realize high
follow-up force and achieve high quality welds.

What are PULSETIG welders?
®
PULSETIG® welders are TIG welding power supplies that induce arc discharge to perform
welding. These welders digitally control welding current and welding time. They can be
used to perform arc welding on precision components and very small components.
PULSETIG® welders allow shielding gas to flow from torches and the power supply
generates a high voltage in the shielding gas to induce arc discharge between the
tungsten electrode and the workpiece. Metals are fused for bonding as a result of
heating by the high-temperature arcs. When welding copper by resistance welding or
laser welding, the high thermal conductivity and
reflectivity of copper make it difficult to weld. However,
our PULSETIG® welders easily overcome this issue. In
addition, our PULSETIG® welders have been designed
to perform various types of welding: welding of
high-melting point materials such as tungsten; welding
of different types of metals; and welding of thin magnet
wires 0.02 mm in diameter.

PULSED HEAT CONTROLLERS
Pulsed heat controllers
Our pulsed heat controllers precisely control welding temperature
and time to realize high-quality solder joints and thermal caulking of resin!
MR-130B
Specifications for pulsed heat controllers
Transducer-integrated model
Power supply type
Pulsed heat controllers control heating temperatures and heating times to achieve the optimal temperatures required
for workpieces such as precision solder joints.
Our pulsed heat controllers can accurately reproduce predetermined temperature waveforms on the basis of real-time
temperature feedback from thermocouples attached to their thermodes. They are optimal not only for solder joints but
also for FFC joints and thermal caulking of resin.
