Double Head Circle Seam Automatic Welding Machine For Tank / Pipe

1. Work-piece showing

Diameter and length: Φ=250-600mm, L=200-2000mm

Materials and wall thickness: SS 6mm, CS 10mm, Al 14mm

Welding method: argon arc welding

Welding requirements: with a smooth, beautiful, no virtual welding and desoldering surface, welding seam fit the strength standard

2. End cap automatic main welding machine and working principle

Work-piece will up or down according to chuck’s move

Back cylinder drive the back chuck to catch and clamp the work-piece, when work-piece unload the chuck will down

Left and right lifting cylinder drive the lifting slider then control the welding gun aimed at the welding seam

DC motor drive the main axis through the main axis box, driven the front chuck rotating the work-piece

Controlled by PLC, then start arc and welding

After finished rise the welding gun and loose the work-piece

Left and right slider could adjust the left or right distance to suit the different lengths of work-piece

Welding gun could up and down adjust to suit the different diameters of work-piece and rotating

3. Main features

End cap automatic welding center (automatic double circle seams welding machine) is suit to CS, SS, Al work-piece, butt welding the two circle seams of the tank at the same time. Welding seam is beautiful, with a smooth surface to ensure the mechanical strength, and also could repair welding at anytime.

4. Main structures

Automatic welding center is consist of main machine, welder source, welding gun system, pneumatic system and electric system

Main machine include lather, main axis box, tail axis box, welding gun movement device

The rotating of main axis box is by permanent magnet DC speed control motor, it could achieve step less control, tail axis box with pneumatic pinch device, if the adjust distance is big, it could adjust the position of whole tail axis box, 3D adjust by welding gun soft adjustment device or manual adjustment

The lather could manual operate, also automatic operate is allowed, PLC control means reliable action and stable working

5. Main technical parameter

Input power: welder source 380V/ 50HZ * 2 sets, main machine 220V/ 1KW

Work-piece diameter: Φ250-600mm

Work-piece length (exclude chuck): 200-2000mm

Pneumatic adjust range: 0.2-0.4MPA

Amount of overlap: adjustable

Main size (L*W*H): 3500*800*2000mm

6. Main configuration

DC motor: famous brand which is made in China

Electric parts: contactor adopts Chint, button adopts AIKS, PLC adopts Siemens or Thinget

Pneumatic parts: famous brand which is made in China

Welder source: Panasonic YC-500WX AC/ DC argon arc welding * 2 sets

7. Action program

Manual

Automatic: manual load the work-piece - first step on loading platform, work-piece rise - cylinder top tight the work-piece - move gun - second step on then work-piece start rotating - welding a circle, automatic stop and rotating, also welding gun back - loading platform rise - back cylinder down - unloading work-piece
