The welding time plays an important role when the medium frequency spot welding machine performs projection welding. If the welding time is too long or too short, it will have a great impact on the welding quality.
When the material and thickness of the weldment are given, the welding time is determined by the welding current and bump rigidity. For workpieces with good welding performance, the welding time is secondary compared with the electrode force and welding current. Usually, after determining the appropriate electrode force and welding current, the welding time is adjusted until satisfactory.
The basic rule is that as the welding time increases, the nugget size and joint strength increase, but this increase is limited, because the increase in the nugget will cause later spatter, which will reduce the quality of the joint. Generally, the welding time of projection welding is longer than that of ordinary spot welding. The current is smaller than spot welding.
The welding time of multi-point projection welding is slightly longer than that of single-point projection welding to reduce the reduction in welding strength caused by multi-point projection welding shunt. The welding time of multi-point projection welding is not a given parameter, but a welding parameter that has been explored through multiple weldings and is locked using a memory program for the next welding.
