Automatic TIG Inner Hole Cladding Machine

 Automatic TIG inner hole cladding machine

I.Welding Requirement 

• To complete the automatic inner hole overlay welding of pipe/tube. Make sure that the form is uniform and has a good appearance, depth of fusion and width of fusion meet the welding requirement, easy to clamp.

• Machine can work continuously for 24-hour.
• Applicable material: stainless steel,carbon steel
• Include cooling system
• This machine also can be used for surface overlaying

 

II.Equipment Feature  

 

Automatic TIG inner hole cladding machine:

 

1. Welding torch moves forward-backward along with axis and welds workpiece. Workpiece is rotating, the welding position is horizontal.
2. Workpiece rotation is driven by power head, end face positioning, rotary welding.
3. It adopts push type wire feeding mode to guarantee the stability of wire feeding.
4. Welding torch can be adjusted longitudinal to suit for various welding type.
5. 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.
6. Welding torch can be adjusted up and down, side to side and angled turn to meet welding requirement.

IV.Equipment Composition

Machine body adopts welded body. Machine base is welded by square tube and steel plate. It will choose annealing heat treatment after welding. Column and boom, rotation axis box and end face positioning mechanism are installed in machine base.

1.Pipe is clamped by rotary chuck and supported by bracket of rolling wheels. Distance between brackets can be adjusted according to pipe length.

2.Rotation Axis Box consists of AC frequency motor, reducer, fixture and conductive sleeve and other components. The rotation speed is adjusted by controlling driver to change motor speed. The workpiece rotation is clamped by chuck. Conductive sleeve adopts flexible copper sleeve, the connection between copper sleeve and workpiece is elastic. Conductive oil is poured between copper sleeve and workpiece, anti-abrasion and good electrical conductivity.

3.Welding Torch Clamping&Adjustment Forward-Backward Mechanism: The welding torch is moved forward-backward, driven by the servo motor, to realize the switch between preparation and welding station. The welding torch adopts push wire type to ensure stable wire feeding. The welding torch can be adjusted up and down, left and right and angled turn. The fine adjustment of the welding torch adopts motor-driven up and down fine adjustment mode and screw adjustment, accurate adjustment, high positioning accuracy. 

      

4.Use special customized TIG welding torch to meet the requirement of such small diameter.
