Abstract (en)
[origin: WO9412312A1] A method of metal-inert gas arc welding which reduces spatter in the welding process, wherein a liquid (8), preferably a hydrocarbon, is dispersed in the inert gas during the welding process. At a weld site (2) the use of the liquid (8) dispersed in the gas prevents any spatter formed from adhering to any surfaces adjacent the welding hand piece (3). The liquid may be dispersed in the gas by passing the gas through the liquid in a container (7) located between the gas supply (12, 13) and the welding hand piece (3), or may be injected into the gas as a vapour or fine mist.
