Description
The Coreweld 46 LS can be used for the welding of thin-plate with a minimum thickness of 1.0 mm and provides fabricators with a substantially faster and higher quality welding solution to solid MAG wire.
The absence or very low levels of silica on the weld surface and minimal spatter result in reduced post weld cleaning before coating/painting.
Coreweld 46 LS is a unique product that markedly lowers the welding costs for mechanised and robotic fabrication.
The many advantages relative to solid wire are associated with the extremely wide spray arc parameter envelope that starts as low as 160A. With solid wire spray arc starts at around 200A for diameter 1.0 mm and 230A for diameter 1.2 mm.
These features are valid for the standard shielding gas M21 (Ar + 15-25% CO2), although optimal results are obtained in 92% Ar + 8% CO2 mixtures.
Switching from solid wire to Coreweld 46 LS will in most cases, require no change in the positioning of the welding gun so the conversion time is limited to the optimisation of welding parameters.
