CWB Module 4 Welding Processes Questions and Answers | Latest Version | 2024/2025 | Correct & Verified What is the primary advantage of flux-cored arc welding (FCAW)? It provides deep penetration and high welding speed, making it suitable for thicker materials. How does the electrode diameter affect the welding process? Larger electrodes are used for thicker materials, while smaller electrodes are better for thinner materials or more intricate welds. What is the difference bet...

Welding Tig Questions and Answers Rated A+ TIG welding uses a non-consumable tungsten electrode. True. The tungsten electrode is not consumed during the welding process. The shielding gas in TIG welding is typically helium or argon. True. Argon is most commonly used, but helium can also be used for certain applications. TIG welding can only be performed on ferrous metals. False. TIG welding is suitable for both ferrous and non-ferrous metals. In TIG welding, the welder can cont...

Tangent - intersects a circle in only 1 place. Secant - intersects a circle in 2 places. Intersection of a tangent and a radius - form right angles when they intersect. Equation of a circle - x minus h squared plus y minus k squared equals radius squared. Circumference of a circle - 2 times pi times radius or pi times diameter. Area of a circle - pi times radius squared. Central angle - is equal to its intercepted arc. Inscribed angle - is equal to ½ its intercepted arc. ...

"When certain stainless steels are heated between 500-850° C, carbides form at the grain boundaries and cause a local depletion of chromium." (A) Oxidization (B) Increased toughness (C) Solution heat treatment (D) Sensitization - Correct Answer-(D) Sensitization Note: Also known as "carbide precipitation" -- Chromium binds to carbi...

GMAW n FCAW Questions and Answers Rated A+ What is the primary shielding gas used in GMAW, and why is it important? The primary shielding gas used in GMAW is argon or a mixture of argon and carbon dioxide, which protects the weld from atmospheric contamination and helps stabilize the arc. How does FCAW differ from GMAW in terms of shielding requirements? FCAW can be self-shielded, requiring no external gas supply, while GMAW relies on an external shielding gas to protect the weld ar...

A consumable electrode is: - ANSWERAN electrode which melts and provides metal to fill the joint The weld heat affected zone is: - ANSWERthe portion of the base metal adjacent to the weld metal whose properties have been changed due to the heat of welding When an arc is formed between two electrodes - ANSWERelectricity flows from negative cathode to positive anode The magnetic pinch force helps in the process of the detaching the molten metal drops from the electrode tip. The magnetic f...

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...
