Joint Edge Misalignment
Weld edge offset is a deviation of the ideal fit-up position of two plate edges in the transverse direction, causing asymmetric cross-section loads and reducing the fatigue life of the weld joint.
Physical-Chemical Mechanism of Action
Misalignment of the joint edges leads to uneven loading on the two plate edges. This can cause stress concentrations and local deformation in the welded joint.
Metallurgical Relevance & Risks in Welding
Misalignment can lead to increased resistance to abrasion, to cracks, or even to deterioration of the mechanical properties of the weld. This affects the part's service life and reliability.
Workshop Practice & Instructions
To avoid misalignment, it's important that the plate edges are precisely aligned. This can be achieved by careful setup and welding accuracy. If you have alignment problems, check and calibrate your tools.
