welding technology for tubular cast tungsten carbide welding rods

The electrode adopts the oxyacetylene welding. Operation process is as follows:

(1) clean up the workpiece, make the welding workpieces surface with metallic luster.
(2) the flat position of welding, therefore can use the appropriate clamping fixture for control of surfacing layer thickness, thick piece of available.
(3) with a neutral flame preheating, flame core not contact surface, the distance to 25 mm is advisable.
(4) when the artifacts of heating to proper temperature, coating a layer of special surfacing can stay in flux, such as the flux has been properly preheating, the flux will bubble boiling, the oxide on the surface of the workpiece is removed flux, continue to heat to the surface of the solvent is full of by overlaying welding and a transparent liquid state, have suggested that began surfacing welding backing weld layer.
