SPOT WELDING

Spot welding is one of the
oldest welding processes. It
is used in a wide range of
industries but notably for the
assembly of sheet steel
vehicle bodies. This is a type
of resistance welding where
the spot welds are made at
regular intervals on
overlapping sheets of metal.
Spot welding is primarily
used for joining parts that
are normally up to 3 mm in
thickness.
MIG WELDING

Gas Metal Arc Welding
(GMAW) is frequently
referred to as MIG
welding. MIG welding is
a commonly used high
deposition rate welding
process. Wire is
continuously fed from a
spool. MIG welding is
therefore referred to as a
semiautomatic welding
process.
PROJECTION WELDING





Projection welding is a variation of spot welding. Projections
are designed in one part. These act as current concentrators
for the welding process. When the two parts are mated
together, these projections are the high points that first make
contact. As the power is cycled, the projections simultaneously
carry the current and are welded.
Due to the efficiency of power transfer, thicker materials can be
successfully welded. Materials as thick as 3 mm (0.125 in) can
be successfully welded.
Low carbon steels, low alloy steels, stainless steels, as well as
aluminum can be welded using this process.
Projections are usually semi-spherical or blunt conical type.
Projection welding requires that the height of projections be
controlled to within a range of 0.075 mm (0.003 in).
