Spot welding is meant as a method for coupling metal parts by means of a weld gun ― at which ends two electrodes are placed ― that, after gripping the parts to be coupled, welds them in one spot without any weld material.

Spot welding should be preferred to arc welding owing to the reduced stress to which the body parts are subject as well as to the lower production costs.

The process is fully automatic, except for loading and unloading the parts to be coupled, operations being carried out by a duly trained operator. Each movement is controlled through a specific software and tested prior to try-out or production stages. After loading the part, the operator will start the working cycle from a pushbutton panel designed according to the ergonomic rules in full compliance with the most stringent safety and reliability standards.
