Automated system for electroarc welding SPTE EW

Purpose

For mechanical repair surface welding with solid wire of sealing surfaces:

■ wedges

■ gate valve housing

■ valve housing

■ valve housings and spools

Principle of operation

■ the surfacing process is automatic

■ the installation can be performed as with a rotating die and rotating
table

■ the consumption of the surfacing wire depends on the diameter and
wear of valves

■ the unit is completed with a power source for the arc

■ operation in the protective gases medium or under a layer of flux

■ table tilt – 0°, 5°, 10°

Advantages

■ eliminates the need for special training through the automating of
the operation

■ quality of preparation and the surfacing process conducting allow the
absence of splashes, overheating of parts

■ use of a surfacing installation in the shielding gas medium is safe due
to the use of a forced cooling automatic system of the welding tool

■ all this allows to increase the service life of the tool, makes the
process reliable, safe, and technologically perfect
