Sense Level 1 Welding Process Certification Test Module 9 Questions and Answers | Latest Version | 2024/2025 | Correct & Verified What is the main goal of a welding inspection? To ensure the weld meets the required quality and design specifications. What is a visual inspection in welding? A process to examine the weld for surface defects such as cracks, porosity, and incomplete fusion. Why is joint preparation important before welding? Proper joint preparation ensures good fusion and minimizes defects. What does the term "weld bead" refer to? The deposit of filler metal that forms the joint. What is the purpose of non-destructive testing (NDT) in welding? 2 To assess the quality of the weld without causing damage to the material. How is porosity identified in a weld? By observing small holes or cavities in the weld metal. What causes undercut in a weld? Excessive heat or incorrect welding angle. What is the function of a fillet weld gauge? To measure the size and shape of a fillet weld. Why is controlling the heat input during welding important? To prevent distortion and maintain the mechanical properties of the material. What is the difference between a weld defect and a discontinuity? A defect is a discontinuity that makes the weld unacceptable based on standards or codes. What is the role of preheating in welding? 3 To reduce thermal stresses and prevent cracking. What is slag inclusion in welding? Non-metallic material trapped in the weld, which weakens its strength. Why is it important to inspect the root of a weld? To ensure proper fusion and penetration at the joint. What is the purpose of a welding procedure specification (WPS)? To provide detailed instructions for producing a quality weld. What is incomplete fusion, and how does it occur? It is the lack of bonding between the weld metal and base metal, often caused by insufficient heat or poor technique. Why is interpass temperature important in welding? It affects the cooling rate and helps prevent
