SENSE Module 5 GMAW Questions and Answers | Latest Version | 2024/2025 | Correct & Verified What type of welding process is GMAW? GMAW is a fusion welding process. What is the most common shielding gas used in GMAW? Argon is commonly used as a shielding gas in GMAW. What type of electrode is used in GMAW? A consumable wire electrode is used in GMAW. What is the effect of increasing travel speed in GMAW? Increasing travel speed generally results in a narrower weld bead. What happens if the voltage is too high in GMAW? Too high voltage can cause a wide, shallow weld with excessive spatter. 2 What is the function of the contact tip in GMAW? The contact tip transfers electrical current to the welding wire and directs it to the weld pool. What is the difference between short-circuit transfer and spray transfer in GMAW? Short-circuit transfer involves the wire touching the base metal, while spray transfer uses a steady, continuous arc with fine metal droplets. What is the result of using incorrect electrode extension in GMAW? Incorrect electrode extension can cause an unstable arc or excessive spatter. Why is proper joint preparation important in GMAW? Proper joint preparation ensures good fusion and prevents defects like porosity. What does DCEN polarity provide in GMAW? Direct Current Electrode Negative (DCEN) provides better heat control and reduces spatter. What is the recommended position for the welding torch in GMAW? The torch should be held at a 10-15 degree angle from vertical. 3 What is a common cause of porosity in GMAW welds? Porosity is often caused by contamination or improper shielding gas flow. What type of weld is commonly used in GMAW for lap joints? Fillet welds are commonly used for lap joints in GMAW. How does travel angle affect the quality of a GMAW weld? The travel angle affects bead shape, penetration, and consistency. What is the role of the wire feed speed in GMAW? The wire feed speed controls the heat input, weld bead size, and penetration. What does a wider weld bead indicate in GMAW? A wider weld bead typically indicates a slower
