Excessive Weld Reinforcement
Macroscopic reinforcement is excessive weld profile that leads to high stresses and possible cracking.
Physical-Chemical Mechanism of Action
Macroscopic excessive reinforcement occurs due to uneven deformation of the weld during cooling. This can be caused by excessive stresses or inaccurate tool guidance.
Metallurgical Relevance & Welding Risks
Macroscopic excessive reinforcement leads to high mechanical stresses at the weld transition. This can result in cracks, hot cracks, or weld fracture. It can also impair the strength and ductility of the entire component structure.
Workshop Practice & Action Instructions
To avoid macroscopic excessive reinforcement, ensure even deformation during welding. Keep stresses below the permitted maximum and use suitable tools with precise guidance. If excessive reinforcement is suspected, carefully inspect the weld and check for cracks or deformation.
