Automatic Surfacing Machine for Corrosion Resistance Overlay on the Inner Wall of 90° Degree Elbow


Automatic Surfacing Machine for Corrosion Resistance Overlay on the Inner Wall of 90° Degree Elbow

Application: It is mainly used for automatic surfacing of the corrosion resistance overlay on the inner wall of bent pipes in pressure vessels for petrochemical industry and nuclear power plants. The inside diameter capable of being welded is 250-500mm, and the curvature radius is 400-800mm.

Main technical characteristics:
   ·The workpiece is installed onto a two-dimensional positioner, and the welding gun is installed onto a three-dimensional guide rail. Five axes move coordinately based on certain mathematical models to ensure an automatic welding process.
   ·The workpiece can be always in the flat position for welding by successively adjusting position.
   ·The beads can be automatically arranged by human-computer interface input of technical parameters.
   ·The machine has functions of breakpoint memory and automatic reset.
   ·The water cooling system in the 90° bent welding gun is suitable for longtime successive welding in high temperature environment.
