WEL 2040 - Advanced Gas Metal Arc Welding

Clock Hours: 100

Delivery Mode
on-ground

Course Description:
The goal of this course is the continuation of Gas Metal Arc Welding related theory and practices for the joining of carbon steel plate. This course adds the FCAW (Dual-shield Fuxcore) process, and GMAW Axial-Spray transfer to join carbon plate steel in the Flat position. GMAW-S (Short Circuit Transfer MIG) fillet and groove welds are performed in the Vertical and Overhead positions. Weld soundness is accessed and graded by AWS D1.1 criteria for visual testing, and AWS B2.1 Criteria for destructive testing using Guided Bend and Fillet Break Tests *** Aluminum GMAW is also introduced in the Flat and Horizontal positions***

Student Learning Outcomes:
Students will be able to demonstrate knowledge of:

Demonstrate how to perform single pass fillet welds on lap-joints and Tee-joints in the 3F and 4F positions using GMAW-S (Short-Circuit transfer MIG)
Demonstrate how to perform open-root, square groove butt joint welds in the 3G and 4G positions using GMAW-S (Short-Circuit transfer MIG)
Demonstrate how to prepare a beveled surface on plate steel coupons
Demonstrate how to properly set-up and tack weld a single Vee, butt-joint coupon with backing
Demonstrate how to perform a multi-pass weld on a single Vee, butt-joint coupon with backing using FCAW-G (Dual Shield Fluxcore) in the 1G position
Demonstrate how to perform a multi-pass weld on a single Vee, butt-joint coupon with backing using Axial-Spray transfer GMAW (Spray arc MIG) in the 1G position
Demonstrate how to lay-out and saw welded coupon straps for guided bend tests
Demonstrate how to remove backing from coupon straps with oxy-fuel torch prior to guided bend testing
Demonstrate how to perform ASME Section IX style mock-flange welds on a welding positioner in the 5F positon using Axial-Spray transfer GMAW
Demonstrate how to perform fillet welds on lap-joints and Tee-joints in the 2F position using Aluminum GMAW
Explain the differences between a spool-gun and a push-pull gun for Aluminum GMAW
Explain the differences in cost and application selection for FCAW processes and GMAW processes
Explain the thickness limitations for GMAW-S and Axial-Spray Transfer GMAW
