WELDING LAYOUT AND FITTING
Catalog Description:
63 - Welding Layout and Fitting
(May be repeated three times)
2 units
Theoretical and practical application of welding blueprints on welded assemblies and
subassemblies. Welding power source classification and process identification, welding joint
discontinuities, defects and distortion, AWS codes, standards and recommended procedures, use
of jigs, fixtures, holding devices, and welding sequences techniques to control welding distortion,
methods of straightening and restoring the dimensions of finished products. Laboratory includes
Arc, MIG, TIG, and Flux-core welding, plasma and fuel cutting. Strongly recommended:
