Cwb Level 1, Mod 4 - Welding Processes & Equipt Fully Solved 2023/2024

15 degrees using a push technique {Ans: What travel angle and technique should be used with MCAW for a flat profile and good penetration?}Advantage: High productivity. Disadvantage: Can't do in-position welding. {Ans: What is the greatest advantage and disadvantage of SAW?}The deposition rate will increase, but the penetration is reduced and the risk of incomplete fusion in groove welds is increased. {Ans: What is the effect of a change in polarity from DCEP to DCEN on SAW weld deposits?}30% arc heat at the electrode. 70% arc heat at the work. {Ans: What is the percentage of arc heat at the electrode and at the work when using the GTAW process with current set to DCEN?}They are classified in conjunction with the welding wire, forming a flux-wire designation. {Ans: How are SAW fluxes classified?}High current, low voltage {Ans: Describe the current and voltage of a welding arc}
