High-Low Joint Misalignment
Edge misalignment is a displacement of plates or pipes in the welding direction, leading to uneven stress and reduced load-bearing capacity.
Physical-Chemical Mechanism of Action
The edge offset is caused by a displacement of sheets or pipes in the direction of the welding beam. This leads to an uneven stress distribution on the weld, since the material parts are pulled to different degrees.
Metallurgical Relevance & Risks during Welding
A high edge offset increases the stress at the corners and leads to an increased risk of cracks and wear. This can significantly affect the load-bearing capacity of the structure and shorten the lifespan of the weld.
Workshop Practice & Instructions
To minimize the edge offset, the sheets or pipes must be aligned exactly. This can be achieved using fixtures such as centering systems and welding stands. An edge offset should be kept under 0.5 mm to ensure a safe and load-bearing weld.
