Automatic Surfacing Machine for Corrosion Resistance Overlay on Tube Inner Wall


Automatic Surfacing Machine for Corrosion Resistance Overlay on Tube Inner Wall .

Application: It is mainly used for automatic surfacing of the corrosion resistance overlay on the inner wall of tubes in pressure vessels for petrochemical industry and nuclear power plants. The maximum inside diameter capable of being welded is 50-500mm, and the largest length is 2000mm.

Main technical characteristics:
 One set of equipment with two surfacing procedures: dual-gas shielded TIG  surfacing with filler wire and CO2 gas shielded surfacing with flux-cored wire. 
 The beads could be automatically arranged by human-computer interface input of technical parameters.
 The machine has functions of breakpoint memory and automatic reset.
 The automatic arc voltage tracking system can help to improve welding quality.
 Three sets of water cooling systems in one subminiature superpower water cooling welding gun suitable for longtime successive welding in high temperature environment.
