Corequisite WLD 100
WLD 150 METAL FABRICATION AND RIGGING
3 (1-4)
Basic metal fabrication tools and equipment utilizing various
measuring tools, geometric nomenclature, basic layout and
assembly skills along with shape construction, and triangulation
from scale drawings, advanced metal fabrication tools, developing
assemblies and sub-assemblies from working prints using various
fabrication processes. Identify individual parts and weldments
utilizing materials lists. Additionally: tools of rigging, and lifting,
hardware, slings, hoists, ladders and scaffolding, weld distortion
control, and basic CNC programming will be incorporated.
Qualification with groove welds qualifies for both groove and fillet
welds so an emphasis is placed on plate groove weld tests. The
processes covered are Shielded Metal Arc Welding (SMAW), Gas
Metallic Arc Welding (GMAW) and Flux-Cored Arc Welding (FCAW).
All positions of welding will be performed in these processes.
Serves as a final preparation for students for American Welding
Society (AWS) certification tests administered in the lab.

Corequisite WLD 100
WLD 160 GAS METAL/FLUX CORED ARC WELDING
5 (2-6)
Focus on Wire Feed Arc Welding processes: Gas Metal Arc Welding
(GMAW) Solid wire short-circuit and spray transfers, Flux Cored Arc
Welding FCAW-GC (gas shielded) and FCAW-SS (self-shielded)
welding, electrode selection, equipment set-up and operation,
weld joint types, and all-position lab modules geared towards
qualification testing.
Prerequisite WLD 100
WLD 170 METALLURGY
2 (2-0)
Introduction to Welding Metallurgy. A study of ferrous and
nonferrous metals from the ore to the finished product. Emphasis
on: metal alloys, heat treating, hard surfacing, welding techniques
and their effect on metal, forging, foundry processes. Mechanical
properties of metals including hardness, machinability, and
ductility.
Prerequisite None
WLD 180 GAS TUNGSTEN ARC WELDING
3 (1-4)
Provides knowledge of theory, safety practices, inert gas,
equipment, and techniques required for successful gas tungsten
arc welding. Qualification tests, all positions, are used in the
evaluating of student progress toward making industrial standard
welds on ferrous and non-ferrous metals. Topics include GTAW
safety and health practices; shielding gases; metal cleaning
procedures; GTAW machines and equipment set up; selection of
electrodes and filler rods; GTAW weld positions; and production of
GTAW beads, bead patterns, and joints.
Prerequisite WLD 100
WLD 220 WELD INSPECTION AND TESTING
1 (1-1)
Students are introduced to the functions of quality
assurance/control programs and the techniques for inspecting
welds. Reference and interpret welding codes and specifications to
accurately evaluate weld flaws and discontinuities. Students also
learn destructive and non-destructive weld testing methods
commonly used in the welding industry.
