Embodiment 2

[0023] A rear argon arc welding torch is also arranged behind the plasma welding torch along the surfacing direction;

[0024] Said step also includes S6, setting the starting position of the rear argon arc welding torch to start remelting. When the rear argon arc welding torch moves to the starting position of the rear argon arc welding torch along with the plasma welding torch, the rear argon arc welding torch will be automatically started, and the rear argon arc welding torch will remelt the completed surfacing welding surface to complete the composite deposition of the workpiece weld.

[0025] The main function of the rear argon arc welding torch is to remelt the surfacing layer. Argon arc remelting can provide hydrogen-eliminating post-heat treatment for the surfacing layer, effectively reduce the surfacing stress, improve the shape of the weld surface, promote the overflow of hydrogen in the workpiece, and eliminate the pores of the surfacing layer.

Abstract

The invention relates to a plasma composite surfacing process, which comprises the following steps: S1, cleaning a workpiece; S2, surfacing preparation; S3, surfacing position confirmation; S4, carrying out surfacing work; and S5, composite surfacing. The plasma composite surfacing process provided by the invention has the advantage of improving the plasma welding surfacing effect.

Description

technical field [0001] The present application relates to the field of plasma surfacing technology, in particular to a plasma composite surfacing process. Background technique [0002] Plasma surfacing is the use of ionized plasma arc to melt the base material and welding powder and form them in solid state on the surface of the base material. Its main disadvantage is that the bonding force between the surfacing layer and the base material is weak, especially the surfacing of alloys with large differences in physical properties. For example: the plasma surfacing welding of the Stellite (Stellite) series alloy of the carbon steel gate of the valve has the risk of falling off due to the weak combination of the surfacing layer and the base material. The generation of cracks, and the repair of cracks is difficult. Contents of the invention [0003] In order to overcome the above technical problems, the present application provides a plasma composite surfacing process. [00...
