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...

Level 3 Module 29303 FCAW – Pipe Questions and Answers Rated A+ What is the primary advantage of using FCAW for pipe welding? The primary advantage of FCAW for pipe welding is its ability to produce strong, high- quality welds quickly while accommodating various pipe orientations and positions. How does FCAW enhance penetration in pipe welding compared to other methods? FCAW enhances penetration by using a larger volume of molten metal and a controlled heat input, allowing for dee...
