BRX 210 – Mechanical Blue Print Reading
Course Outline: Module 7
Units 22 & 23 –Symbols on Welding Drawings and Control
Diagrams
Introduction
Module 7 introduces Industrial drawings that depend on symbols to communicate specialized information
to the print reader. Welding drawings and instrumentation and control drawings (also called graphic
diagrams) provide instructions to a fabricator or troubleshooter about finishing a component and how
components will work together in sequence.
Learning Objectives
NOTE: You will be turning in the Objectives Worksheet with each Module Outline.
After completing this module, you will be able to:
In Unit 22:
1. Identify a welding symbol.
2. List the elements of a welding symbol.
3. Explain the meaning of a welding symbol.
4. Identify the basic weld symbols used in welding symbols.
In Unit 23:
1. Describe the types of control diagrams.
2. Identify symbols used on fluid power diagrams.
3. Recognize supplementary information accompanying circuit diagrams.
4. Read a graphic diagram.
5. Interpret graphic diagrams for fluid control devices.

Learning Activities
The learning activities section is a way for you to sequence your students learning. Consider this as
your way of guiding them to understanding and scaffolding their learning. Be creative, use the right
tool for the right objectives and whenever possible integrate knowledge checks with feedback and/or
reflection. Be sure to provide an overview of each activity in the sequence and how it will help the
learner achieve the learning objectives. Add learning activities as necessary.
This is where you would insert lessons if you choose to use them: Lesson 1, Lesson 2, etc. See the
example below.
Be sure to delete from this template, any activities that you do not plan to use in this module. For
example, if you will not use a “Interactive Case Study”, then delete the entire activity on Interactive
Case Study.
Reading
Read Unit 22, Welding Prints, in Print Reading for Industry, pages 421 - 426.
Welding drawings are detail drawings called inseparable-assemblies. Multiple components are
welded together to make one part. To communicate welding information to a fabricator a symbol
containing specific information is attached at the location for the weld. In Unit 22, you will be
introduced to welding terminology and welding symbols.

Interactive Lecture
M7 – Unit 22, Welding Prints
Welding symbols communicate important information to the welder concerning the location, size
and strength of a weld. All of the instructions a welder needs to correctly fabricate a part are
included in the welding symbol.
The interactive lecture meets learning objectives 7.1, 7.2, 7.3, 7.4,

Welding prints are detail drawings that include the symbols for welding specification. Because a welding
print also includes separate components to be welded together it is called an inseparable assembly and
will include a parts list.

Graphic diagrams are the “behind the scenes” controller that tells your phone what to do when
you press a button on the number pad. The system of components too small to see on the
circuit boards inside the phone work similarly to when a light switch is flipped from off to on so
electricity waiting in the wire can speed past the switch to a light fixture. The path taken by
power, either electrical or fluid, is mapped out on an instrumentation and control diagram.

Interactive Lecture
M7 – Unit 23, Instrumentation and Control Drawings
Instrumentation and control diagrams use symbols and lines to chart the path of electrical or fluid power.
Learning the terms used in graphic diagrams and following the sequence of operations are important
steps toward understanding how electrical or fluid energy can be transformed into mechanical energy.

Graphic diagrams rely heavily on symbols and lines to map the path of electrical and fluid power. Reading
an instrumentation and control diagram requires a specialized vocabulary and understanding of how
components function.
