Fusion Forge and Short Cycle welding processes

To perform the welding, an energy source is needed that supplies CC continuous current, with the particular characteristics of intensity / time necessary for the process and a generally mobile device (Gun) that performs the function of support/coupling of the element to be welded and the protection of the welding with ceramic or gas.

 

procesos soldadura ff

-Process 783 Fusion Forge, Welding of stud bolts by induced arc with ceramic ferrule or gas for protection.

1-1 Positioning of the stud and ceramic in the piece to be welded.

1-2 Distance of elevation, before priming.

1-3 After triggering, the arc melts the end of the stud and the base material piece; the stud after the welding time has passed, is sunk in the fusion bath and the base material.

1-4 The bath solidifies, the union takes place on its entire surface. The ceramic is removed.

2.1 Welding with gas protection, similar to point 1-1, the ceramic is substituted.

-Process 784, welding of stud bolts by short-cycle induction arc, with gas protection or without gas.

3-1 Similar to point 1-1

This process is used on thin sheet metal, to obtain less penetration and for stud bolts with diameter of less than 12 mm.  (FD).

-Process 785 Welding of stud bolts by induction arc with CD Capacitator Discharge

This process is very similar to fusion forge, characterised by shorter welding time and the supply of current by the discharge of a batter of capacitators.

Sufficient penetration of 0.3 mm is obtained but less than in the F.F. process. Ideal for welding on thin sheet metal, it does not deform it and does not damage the reverse side; appropriate for processes which require low heat input.
