Heating element butt welding

Sources of failure

Wrong calculation of the welding pressure
Non-observance of the heating-up time, relocation time or preparation time of joining pressure
Non-observance of welding temperature (too high or too low)
Machine is defect
Machine is not calibrated
Chosen welding pressure cannot be maintained (e.g. because of leaky piston connection)
Contaminated joint surfaces
Wrong material matching
Material residues at heated tool
