GMAW Wire Feed Welding Questions and Answers 100% Pass What is the key benefit of using GMAW compared to traditional stick welding? GMAW offers a continuous welding process, leading to higher productivity and cleaner welds with less slag. How does wire feed speed correlate with weld quality in GMAW? An optimal wire feed speed is crucial; too slow can lead to undercutting, while too fast may cause burn-through or inconsistent bead appearance. Why is it important to clean the base ...

GMAW & FCAW (REVIEW QUESTIONS) WITH COMPLETE SOLUTIONS What happens to the weld pool if the travel speed is too fast during GMAW? If the travel speed is too fast in GMAW, the weld pool may not have enough time to fill the joint properly, leading to incomplete fusion and weak welds. How does the composition of the flux affect the welding process in FCAW? The composition of the flux in FCAW can influence the arc stability, slag removal ease, and the mechanical properties of the final we...
