Weld Quality Level
The weld quality class defines allowable imperfections in welds and ensures the necessary load-bearing capacity.
Physical-Chemical Mechanism of Action
The weld quality class refers to the accepted variations in the weld, such as waves or unevenness. These irregularities affect mechanical strength and behavior under load.
Metallurgical Relevance & Welding Risks
A quality class that is too high (too many irregularities) can reduce the load-bearing capacity of the weld, leading to cracks or failure. A class that is too low requires more effort and time for inspection and can be unnecessarily expensive.
Workshop Practice & Instructions
Determine the correct quality class based on the desired load capacity and application area. Use appropriate welding processes and parameters to keep irregularities within allowable limits. Regularly check weld quality through visual inspection or ultrasonic testing.
