Prepare for your examinations with a set of multiple choice questions (MCQs) related to Inspection and Testing for Welder Trade. The questions are likely designed to test a user’s knowledge or understanding of Mechanic Diesel concepts and may be useful for exam preparation or self-assessment. The website may be a helpful resource for individuals studying to become Welder or seeking to improve their understanding of Welder principles.

INSPECTION and TESTING

What is the purpose of inspection in welding? Determine faults and quality weld Determine the material Determine the welded metal Determine the electrode fusibility

How many stages are there in visual inspection in NDT? Two stages Three stages Four stages Five stages

Which type of test is generally not used on the final product? Non-destructive test Semi Destructive test Destructive test Non destructive and semi destructive

What are the common welding tests performed in the workshop? Nick break, freebend, fracture Tensile test Guided bend test Impact and particle test

How many types of common non destructive test are there? 2 types 3 types 4 types 5 types

What type of test is a visual inspection test? Non-destructive test Destructive test Non-destructive and destructive Performance test
