Weld inspection
Weld inspection checks the quality of a joint using destructive and non-destructive methods. It ensures that technical specifications are met.
Physical-Chemical Mechanism of Action
Weld inspection involves various tests to verify the mechanical and chemical quality of a joint. Destructive methods like the break test tear the weld apart, while non-destructive methods like ultrasonic testing or X-ray screening analyze the internal structure.
Metallurgical Relevance & Risks in Welding
A defective weld can lead to various problems, such as reduced mechanical strength, deformation, or corrosion. Inspection ensures that the weld meets the necessary technical requirements and behaves stably over time.
Shop Practice & Action Guidelines
For successful weld inspection, follow these steps:
1. Preparation: The weld must be clean and free of contaminants.
2. Selection of Test Methods: Depending on the application and material, choose suitable destructive or non-destructive methods.
3. Execution of Tests: Perform the chosen tests according to standards, e.g., break test for mechanical strength or ultrasonic testing for internal structure.
4. Evaluation and Documentation: Evaluate the results and document them thoroughly.
