Welding Alloys in the preparation before welding and welding protection how do
Prior to welding, grinding on a metal surface the welding groove on both sides 25mm width to remove the oxidized color, and washed with acetone to remove grease moisture and other contaminants on the 25mm width and wire welding groove on both sides; must be thoroughly to remove the oxide film; should put an end to useless welding consumables, the welders dirty clothes hazardous substances pollution.
Under the the argon protection of the hot end of the molten pool and
Welding Wire process has always been at the nozzle, the temperature above 300 ℃ the weld should use drag hood protection. The large torch nozzle in order to maximize the shielding of the molten pool in the protection of air flow into, should always hot end of the wire to stay in the bath. Cut wire ends before re-arcing wire end has been oxidized. The the multilayer welding, each layer to be used for drag cast under the protection of high-temperature weld. The protective effect of good or bad judgment can weld surface color silver white.
