3.1 Applications
3.1.1

MIG/MAG pulse welding

Welding process for optimum welding results when joining stainless steel and aluminium thanks to
controlled drop transfer and targeted, adapted heat input.
3.1.2

MIG/MAG standard welding

Metal arc welding using a wire electrode whereby gas from an external source surrounds the arc and the
molten pool to protect them from the atmosphere.
3.1.2.1

coldArc

Welding process for joining thin panels and root layers, steel, chrome/nickel and aluminium as well as for
mixed joints. Also suitable for welding large air gaps in all layers.
3.1.2.2

forceArc

Welding with a powerful forced arc, deep fusion penetration and virtually spatter-free weld seams of the
highest quality.
3.1.2.3

pipeSolution

Reduced-energy MAG welding. X-ray-proof welding of pipelines and pipework without lack of fusion. Root
pass and fill and final pass with or without air gap. Low- and high-alloy steels with solid and cored wires.
3.1.3

TIG (Liftarc) welding

TIG welding process with arc ignition by means of workpiece contact.
3.1.4

MMA welding

Manual arc welding or, for short, MMA welding. It is characterised by the fact that the arc burns between
a melting electrode and the molten pool. There is no external protection; any protection against the
atmosphere comes from the electrode.
3.1.4.1

Air arc gouging

During air arc gouging, bad welding seams are heated with a carbon electrode and then removed with
compressed air. Special electrode holders and carbon electrodes are required for air arc gouging.
