GENERAL DESCRIPTION OF SUBJECT MATTER FOR EACH LECTURE/DISCUSSION
|
Topic
|
General Description of Subject Matter
|
|
Gas Metal and Flux Core Arc Welding
|
Contrast the various GMAW metal transfer methods, considering arc characteristics, weld characteristics and out of position welds. Select the proper arc welding machine, wire feeder, shielding gas, flow rate, contact tube, nozzle size, and welding wire type to produce an acceptable weld. Contrast the various types of shielding gases used for GMAW and how they affect the shape and penetration of the completed weld. Properly assemble and adjust all the equipment required to produce an acceptable weld using GMAW. Correctly prepare metals for welding. Weld using GMAW, make acceptable welds on all types of joints in all positions using GMAW. Identify the potential safety hazards associated with the GMAW process, be able to pass a safety test on proper use of the GMAW process.
