Welding processes and equipment

Other processes

In MIG/MAG, TIG, MMA or SAW, the welding engineer first considers the arc and weld pool. In this group, the logic changes: some processes form a solid-state joint by pressure and plastic deformation; others use a chemical reaction, induced current, a slag pool, an electromagnetic impulse or a very short discharge.

Topic overview

In MIG/MAG, TIG, MMA or SAW, the welding engineer first considers the arc and weld pool. In this group, the logic changes: some processes form a solid-state joint by pressure and plastic deformation; others use a chemical reaction, induced current, a slag pool, an electromagnetic impulse or a very short discharge.

Not the process name but the joining mechanism: melting, diffusion, plastic deformation, discharge, induction heating or chemical reaction.

There may be no conventional bead or filler material, and the critical variable may be force, amplitude, lift height, burn-off, discharge energy or vacuum.

Series production, rotating components, aluminium profiles, battery terminals, studs, thick vertical joints, rails, tubes and transition joints.

What the module covers

  • Other welding processes
  • ‘Other’ does not mean marginal. It means the energy source is no longer a conventional arc.
  • Rapid map according to ISO 4063
  • Overview of processes, equipment and critical variables
  • Thin sheet, electrical terminals and low-heat-input applications. Risks: weak bond, excessive indentation and inconsistent discharge.
  • MAGNETICALLY IMPELLED ARC BUTT (MIAB)
  • Tube-to-tube and ring joints. Risks: non-uniform heating, oxide inclusions, misalignment and inadequate upset.
  • Studs / magnetic pulse
Educational content does not replace current standards, approved WPS/WPQR documentation or decisions by competent welding coordination personnel.
