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.

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.
