High-Low Misalignment
Edge misalignment is the difference in height between the edges of the sheets to be joined. It causes bending stresses and notch effects that strain the part. It must remain within specified limits.
Physical-chemical mechanism of action
Edge misalignment occurs due to unequal sheet thickness or faulty alignment of the edges to be joined. This leads to local bending stresses and notch effects in the part.
Metallurgical relevance & risks during welding
Excessive edge misalignment can lead to increased stresses and loads on the part, resulting in cracks or deformation. This affects the strength and mechanical behavior of the weld.
Workshop practice & instructions
Ensure that the edges of the sheets to be joined are parallel to each other and have the same height. Edge misalignment of up to 0.5 mm is usually acceptable. Use tools such as clamps or presses to align the edges precisely.
