Overview

Straight seam welders are designed for straight line welding of all weldable metals in thicknesses from 0.3mm to 12mm and length up to 3000mm.It adopts the keyclamp device to support uniform and stable holds and cooling effect,which removes the surplus heat through welding seam,in order to reduce the warping and distortion of workpieces.

Key Features:

1. The welding machine adopts cantilever structure after annealing to stress two cantilever beam welding process to ensure long-term beam is not deformed.

2. Pneumatic pressing key type structure, closely spaced along a straight seam on both sides to ensure the butt welds over the entire length of the weld pressed uniformly; about keys pressed finger pitch is adjustable to accommodate different welding workpieces.

3. The thickness of the workpiece size by cylinder type, to ensure that there is sufficient clamping force to prevent the thermal deformation during welding; welding torch using the lift cylinder, and make X / Y direction fine-tuning.

4. Welding mandrel inlaid with copper mold, providing a back seam gas protection; processing of different welding processes according to the cylinder groove or flat workpieces, to side welding.

5. The welding mandrel and the keys pressed finger pitch is adjustable, can be adapted to different workpieces welding requirements; workpiece center position, can be pneumatic or manual. Accurate positioning, easy to operate.

6. Torch walk DC servo motor, rack and pinion drive, the track surfaces are polished, smooth running, stable and reliable welding.

7. All trachea, cables housed within the towline, clean and beautiful appearance, while avoiding cable disconnection.

8. The machine adopts imported PLC control, DC motor drive, adjustable speed, one-button operation, for a variety of welding processes MAG / MIG / TIG / CO2.

Welding Objects & Process :
 
• welding objects: outside cylinder straight seam welding
 
• workpiece weld area should ensure that no grease, burr and factors effecting welding quality.  
 
• material: carbon steel,stainless steel,etc.
 
• range: shell outer straight seam welded: 100mm ≤φ≤ 3000mm. length ≤ 3000mm.thickness 0.3mm ≤δ≤ 12mm
 
 welding mode: keys of the workpiece clamping fixture fixed, torch linear motion to achieve outside the cylinder longitudinal seam weld.
