Weld Alignment
Weld alignment is the exact position of the weld axis relative to the main stress directions of the component. Optimal alignment improves stress distribution and prevents cracking.
Physical-Chemical Mechanism of Action
The weld orientation affects how stresses are distributed in the weld. A non-optimal orientation can lead to localized stress areas that overstress the material and can cause cracking.
Metallurgical Relevance & Welding Risks
Poor weld orientation increases the likelihood of cracking and hot cracking. The material can be locally overstressed, leading to stress concentration and shortening the service life of the weld.
Workshop Practice & Action Instructions
Make sure the weld runs parallel to the main stress direction. Use fixtures such as clamping jigs or stress equalizers to ensure accurate positioning. For complex structures, always consult the component documentation.
