WEL 3035 - Gas Tungsten Arc Welding

Clock Hours: 196

Delivery Mode
on-ground

Course Description:
The goal of this course is the continuation of Gas Tungsten Arc Welding related theory and practices for the joining of carbon steel plate and the introduction of Stainless Steel and Aluminum plates as well as carbon steel pipe. Fillet and groove plate welds are performed in the Vertical and Overhead positions 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.

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

Demonstrate how to perform open-root, square groove butt welds in the 3G and 4G positions

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 in the 1G position

Demonstrate how to lay-out and saw coupon straps for guided bend testing

Demonstrate how to remove backing from coupon straps using oxy-fuel torch prior to guided bend testing

Demonstrate how to perform single pass fillet welds on lap-joints and Tee-joints on Aluminum plate in the 1F, 2F 3F & 4F positions

Demonstrate how to perform Freehand weaves on 304 stainless steel plate (Stringers) using a laywire technique in the 1G position

Demonstrate how to perform a tight-weave fillet weld on 304 stainless steel plate Tee-joints in the 1F position

Demonstrate how to perform a filler-free fuse weld on 304 stainless steel plate lap-joints in the 1F position
