FAB3060 Arc Welding 4
Advanced · 1 credit · TMT - Trades, Manufacturing and Transportation
- Description
- Students apply and extend positional welding skills by using a variety of common electrodes and thickness of materials.
- Prerequisite
- FAB3050: Arc Welding 3
- Parameters
- Access to a welding facility, complete with Shielded Metal Arc Welding (SMAW) equipment and supplies, and to instruction from an individual with welding trade qualifications.
Outcomes The student will:
1 explain the effects heating and cooling have on a weld and weldment
1.1 describe the effect of single and multiple pass welds on the base metal and previously deposited filler metal
1.2 explain the effect cold working conditions might have on weld quality
1.3 explain the need to preheat or postheat
1.4 describe the factors to be considered when choosing an electrode including:
1.4.1 static and dynamic loading
1.4.2 weld position
1.4.3 materials to be welded
1.4.4 current supply
1.4.5 ease of use
1.4.6 joint design and alignment
1.4.7 rate of deposit
1.4.8 depth of penetration
1.4.9 weld finish
