Lonitudinal Seam Welding Machine

•  Automatic Longitudinal Seam Welder series are mainly used for welding longitudinal seam of thin sheet.

•  It adopts cantilever type, and it is mainly composed of frame, fingers-type clamping unit, water-cooling mandrel, travelling carriage, crossing slider, wire feeder and torch holder.

•  Fingers-type clamping unit owns special push from air cell, pressure of air cell is adjusted between 0 to 7kg/cm2, and the distance of two banks of fingers between 5 to 20mm to satisfy various welding seam width; Water-cooling mandrel is designed according the work pieces' diameter and length to ensure the strength.

•  The top of mandrel is inserted water-cooling insert with groove for heat-sink cooling. It is adjustable in mandrel height to handle various material thicknesses. Beam is fitted with travel carriage which is moved straightly by track and driving unit, variable speed.

Introduction:

1. Workpiece clamping adopts pneumatic compression devices with keys, parts balanced force, small deformation of the workpiece.

2. Apply in high-quality, low-distortion linear seams welding. Such as: petroleum chemical container, solar water heaters, electric water heaters, pipe manufacturing, and automobile industries mechanized welding.

3. With PLC control, DC motor drives, stepless speed regulation, automatic welding control system, and oscillation with a linear device for Optional.

4. With different guard ring and groove in line on the back of the welding seam, welding can be 100% penetration, and to ensure that one side welding with back formation.

5. Welders piece thickness is 0.4 ~ 8mm, welding speed is 0.2 ~ 2.2m/min.

Automatic longitudinal seam welding system can use different welding process, such as welding; gas shielded welding, plasma welding, etc.

Technical Parameters:

Application:

The device can be widely used in many fields for longitudinal seam welding such as aviation, spacecraft, thin-walled pressure vessel, auto parts, medical equipment, building decoration, household appliances, food machinery manufacturing industry.

1) Welding torch pneumatic moving up and down, the work piece is fixed,seam is flat.

2) Work pieces positioning and centering by pneumatic, and pressing by the pneumatic keys, welding position can not offset.

3) Welding torch can be up and down, left and right, forward and backward and angle adjusted, in order to meet the welding requirements.

4) The control of the whole machine is PLC, AC variable frequency speed regulation, ensures the euqipment reliability.

5) Added copper backing strap, ensures reverse side forming.

6) Welding form can be preset, storing and transferring. Through the man-machine interface can easily change the parameter and state transition.
