What is the welding stress of medium frequency spot welder?


The welding stress of intermediate frequency spot welder is the stress caused by welding of welded components. The root cause of welding stress and deformation is the non-uniform temperature field and the local plastic deformation and different specific volume structure caused by it.

Refers to the stress generated in the weldment. It is the main cause of structural deformation and crack formation. Welding stress can be divided into transient thermal stress and welding residual stress. Stress release: refers to the phenomenon that the stress at a certain point in the object is reduced due to the release of energy; Energy release, to be exact.

When the uneven temperature field caused by welding has not disappeared, the stress and deformation in the weldment are called transient welding stress and deformation. The stress and deformation after the welding temperature field disappears are called residual welding stress and deformation.

Under the condition of no external force, the welding stress is balanced inside the weldment. The welding stress and deformation will affect the function and appearance of the weldment under certain conditions.
