29106 Weld Quality Part 1 Questions and Answers | Latest Version | 2024/2025 | Correct & Verified What is weld quality? The ability of a weld to meet specified standards and perform reliably under its intended conditions. Why is it important to inspect welds? To ensure the weld is free from defects and meets required strength and durability standards. What is porosity in a weld? Tiny gas pockets trapped in the weld metal, weakening its strength. How can you prevent porosity in welding? By cleaning the base metal, using proper shielding gas, and maintaining correct techniques. What is a visual weld inspection? 2 A method of examining the weld surface for defects like cracks, undercuts, or irregular beads. Why is penetration important in welding? It ensures the weld fully fuses with the base metals for maximum strength. What is an undercut in welding? A groove along the weld toe that reduces the weld’s strength. How can you avoid undercuts? By using the correct welding technique, speed, and voltage settings. What is a welding defect? Any imperfection that reduces the strength or performance of the weld. What is the purpose of destructive weld testing? To evaluate the weld’s strength and performance by physically breaking or stressing it. 3 Why is consistent heat application important in welding? To avoid distortion, weak spots, and uneven welds. What is a weld bead? The deposited filler metal that forms the joint between two materials. What is the significance of weld reinforcement? Extra weld metal on the joint surface that provides added strength. What does the term “slag inclusion” mean in welding? Slag trapped inside the weld metal, reducing its integrity. How can slag inclusions be prevented? By using proper welding techniques and thoroughly cleaning between passes. What is a root pass in welding? The first weld layer that establishes the foundation for additional weld passes. 4 Why is interpass temperature critical in multi-pass welding? To maintain consistent heat and avoid weld cracking or
