Seam Welder Machines
Key Plant manufacture seam welders for SAW, MIG, TIG and Plasma applications.
Increase production and improve consistency and quality of welds with our automated seam welding solutions.
Premium engineered automated seam welders.
We design and manufacture a number of models including external, internal, elevating and flat plate machines.
Machines can be supplied full loaded with welding equipment as a “turnkey” package or as the “steel work only”
Systems can be supplied with operator platforms and infeed and support rolls.
As a global leader and over 65 years in welding automation, we can produce specialised designs to suit large diameter and long length components.
Key Plant supplies seam welders to customers all over the world. Perfect for boiler and gas cylinder manufacturing, our seam welding machines are used in a wide and diverse range of industries.
About Key Plant seam welders
Plate joining can be incorporated with:
- Traversing lines
- Infeed/Outfeed steerable rollers
Internal welding gives smaller weld back bead on the outside of the workpiece, reducing clean-up operations on the external surface.
Easy to load and operate for increased productivity. Remove the gate assembly to feed and offload the workpiece easily.
- Increased diameter range
- Constant working height regardless of diameter
- Cylinders or flat plate used on same machine
- Clamping bed raised and lowered with option of operator platform
- Platform anti-fall safety device.
The advantages of the operator being able to elevate with the clampling bed, by use of an operator platform assist’s the operator’s ability to view in real time the welding and make any small adjustments in set-up or parameters for total flexibility.
