Quality Level
The quality level defines the maximum permissible irregularities in weld surfaces according to international standards. The higher the level, the less tolerance for defects.
Physical-Chemical Mechanism of Action
The quality level indicates how smooth or uneven a weld may be. It refers to the number and size of weld defects, cracks, or other irregularities.
Metallurgical Relevance & Welding Risks
A quality level that is too low can lead to more defects and cracks, which impairs the toughness and reliability of the joint. A level that is too high demands stricter process control and increases costs.
Workshop Practice & Action Instructions
Choose the right quality level based on the component requirements and the welding process. For critical applications like machine building or aerospace, a higher level is required. Use high-quality materials and optimize welding parameters to achieve the desired quality level.
