33 Week 6 Labs
Both of these welds should be completed with gas-shielded welding and 0.045″ diameter E71T-1 wire.
Stringer Beads All Positions FCAW
Setup
Materials required are a single 3/8″ thick steel plate measuring 3″ by 6″.
Positions required are 1G, 2G, 3G, and 4G.
Work
Using FCAW-G, weld 2 layers of surfacing beads on the plate. Each pair of layers should be completed in a different position.
Acceptance Criteria
- Consistent weld
- Good tie-ins
- No undercut
- Complete penetration
- Half overlap over previous weld bead
Angle Iron X-block FCAW
Setup
Materials required are a single angle iron, 1/4″ thick, measuring 2″ by 2″ by 18″.
Positions allowed are 1F, 3F, and 4F.
Work
Using FCAW-G, weld multiple layers of stringer beads inside the x-block. Fill the block completely.
Acceptance Criteria
- Consistent weld
- Good tie-ins
- Consistent overlap
- Complete penetration
