摘要:
A welding wire is provided with a hollow section for accommodating flux. The flux has a composition including: Mn: 5-20%, Si: 1-15%, TiO2: 5-25%, SiO2: 0.1-10%, Mo: 0.1-5% by weight, the balance being iron. When welding low alloy high strength steel by using the welding wire, the slag on the welding bead can be easily cleaned and a smooth surface can be formed on the welding bead which makes it easier to galvanize a zinc layer over the surface of the welding bead. The welding wire provides better welding operation performance and generates less welding spatters.

摘要:
A double wire GMAW welding apparatus having a wire spacing adjustable torch assembly is disclosed. The double wire torch assembly has a wire spacing adjusting mechanism, by means of wire spacing adjustment the torch assembly can be used for a non-synchronized metal transfer weld process. The wires remain parallel before, during, after wire spacing adjustment.
