High strength and load-bearing capacity of the joint

When a weld has been executed in a careful, proper and professional manner, it can be assumed that the welded joint can withstand a greater static load than the stud or the component. When the load limit is exceeded, the fracture therefore occurs outside the weld zone – either in the stud or in the sheet base material.

Therefore, the characteristic values of stud and sheet are decisive for the strength calculation; the load-bearing capacity of the weld does not need to be taken into account in the calculation. The breaking force can thus be quickly calculated using the minimum tensile strength of the materials, see also notes on the calculation of stud welded joints in DVS 0967 [3]. When calculating stud welded joints, a distinction must be made depending on the application and the applicable regulations. A distinction is made between, among other things, static or dynamic stress, compression, tension, bending or torsion. The studs must therefore be designed in such a way that the serviceability and load-bearing safety of the entire component are ensured.
