Basic Welding Level 1 Module 6 Questions and Answers | Latest Version | 2024/2025 | Correct & Verified What is the primary purpose of a welding machine? To generate heat that melts metal to create a bond between two pieces What is a common safety precaution when working with welding equipment? Always wear appropriate personal protective equipment (PPE), including gloves, helmet, and protective clothing What is an arc in welding? An arc is a visible discharge of electricity that creates heat to melt the metal Why is it important to use the correct welding rod? The correct welding rod ensures proper bonding and the strength of the weld What is the function of the electrode in welding? The electrode provides the filler material and a conduit for electrical current to create the arc 2 What type of welding process uses a flux-coated electrode? Stick welding (SMAW) What does "AMPS" refer to in welding? AMPS refers to the amount of electrical current used during the welding process Why is it necessary to clean metal surfaces before welding? Cleaning removes rust, dirt, and oils that can interfere with a strong, clean weld What is the purpose of shielding gas in MIG welding? Shielding gas protects the weld pool from contamination by atmospheric gases What is the difference between MIG and TIG welding? MIG welding uses a continuous wire feed for filler material, while TIG welding uses a non- consumable tungsten electrode What is the role of the welding torch in MIG welding? 3 The welding torch holds the electrode and supplies the shielding gas to protect the weld pool What is the meaning of "penetration" in welding? Penetration refers to how deeply the weld metal fuses into the base metal What is a butt joint in welding? A butt joint is when two pieces of metal are welded end-to-end, aligned in the same plane What is the purpose of a welding helmet? A welding helmet protects the eyes and face from the bright arc light and UV radiation What is the role of a welding ground clamp? The ground clamp provides a return path for the electrical current during welding What is the correct way to hold the welding torch? The torch should be held firmly with a comfortable grip to maintain control of the weld Why is it important to maintain a steady hand while welding? 4 A steady hand ensures a consistent bead
