Batch Inspection
Piece goods inspection checks produced welded structures against quality standards before delivery. It can be done by sampling or completely.
Physical-Chemical Mechanism of Action
Piece goods testing is a process where the quality of welded structures is checked. This involves checking for correct weld shape, missing or excessive welds, and overall mechanical strength and toughness of the material.
Metallurgical Relevance & Welding Risks
Inadequate piece goods testing can lead to safety risks. Defective or faulty welds can cause cracks, failure, or even catastrophic breakdowns in service. Therefore, careful inspection is essential to ensure structures meet technical requirements.
Workshop Practice & Action Guidelines
For piece goods testing, carry out the following steps:
1. Visual Inspection: Check the surface for missing or excessive welds, porosity, and other defects.
2. Mechanical Testing: Test mechanical strength using methods like tensile test or bend test.
3. Non-Destructive Testing (NDT): Use techniques like radiographic testing, ultrasonic testing, or magnetic particle testing to check for internal defects.
4. Documentation: Record all results and notes from the inspection for traceable documentation.
