High-Low Misalignment
Weld misalignment is a height difference between the joined plates or pipes at the joint. It causes bending stresses and reduces durability.
Physical-Chemical Mechanism of Action
Weld seam offset occurs due to uneven deformation or different stresses in the joined parts. This leads to a height difference at the joint, causing mechanical stresses.
Metallurgical Relevance & Risks in Welding
A weld seam offset can lead to increased bending stresses under load. This impairs the durability of the construction and can lead to cracks or failure. Furthermore, it can affect the weld structure, reducing the mechanical properties of the seam.
Workshop Practice & Instructions
To avoid weld seam offset, the parts to be joined should be aligned evenly and straight before welding. This can be achieved through careful preparation and assembly. When selecting the welding process, make sure it is suitable for the material type and does not cause additional stresses. A high quality standard for the weld seam is crucial to ensure a clean and solid joint area.
