Resistance Weldings

The autogenous welding process by pressure is performed without filler material. 
It generates welding points on the perimeter of the pieces to be joined without creating a welding bead (that is, a continuous weld with no interruptions), but realizing multiple points with more or less regular distances between them.

+  Rules for the application of the principle:

  • Butt resistance welding
  • Tack welding
  • Projection welding
  • Flash welding

Arc stud welding (SW)

The welding of studs or bolts (SW), is a special procedure that uses an electric arc and that welds a metal stem on a metal surface.
For this type of welding, the Beccalossi Company uses capacitor discharge welding.
