Automatic MIG TIG Inner Hole Hadrfacing Welding Machine
The core purpose of the internal hole cladding welding machine is to repair internal hole components that have failed due to wear or corrosion through cladding, or to pre-place a high-performance alloy layer on the internal hole when manufacturing new products, thereby significantly extending the service life of the workpiece and reducing replacement costs.
Description
Automatic MIG TIG Inner Hole Hadrfacing Welding Machine

I.Equipment Feature
- Welding torch moves forward-backward along with axis and welds workpiece. Workpiece is rotating, the welding position is horizontal.
- Workpiece rotation is driven by power head, end face positioning, rotary welding.
- Machine has high voltage and slow wire feeding function, which guarantees reliable arc igniting. It also has low welding voltage and low current for filling crater.
- It adopts push type wire feeding mode to guarantee the stability of wire feeding.
- Welding torch can be adjusted longitudinal to suit for various welding type.
- PLC to control the whole operation. The rotation speed of workpiece is adjusted by A/C inverter, stepless adjustment, to improve the reliability of equipment.
