1. Applicable to inside and outside corner seam welding, suitable for outside corner seam welding when the min. Distance from outer edge of the bottom to the shell is 90mm
2. Applicable to butt seam welding of bottom plates
3. With magnetic idler system
4. Adopting sub-arc welding technology
5. Suitable for both Top-to-Bottom and Bottom-to-Top Tank Construction Method
6. More than 99% Qualified first X-ray test.
AUTO Automatic Butt/Corner Seam Welding Machine can be applied to operate effective and efficient welding of but-joint corner seam, lap-joint butt/corner seam, T type corner seam and other different types. It mainly consists of four-wheel drive welding trolley, welding controller, welding power source, wire feeder, trolley travelling control system, welding flux system, welding seam guiding mechanism, welding torch regulating mechanism, cable and so on.
When welding butt seam or lap-joint seam, trolley travels on the rail for welding. When welding the inside & outside corner seam and stiffener ring of vertical tank, because of adopting special magnetic adsorption device, it can also realize automatic welding without using rail.
Automatic Butt/Corner Seam Welding Machine has characteristics of advanced structure, full functions, flexible control, easy operation, which is a high efficient automatic welding equipment to improve welding quality.
Also, AUTO has specially designed Automatic Butt/Corner Seam Welding Machine for LNG tanks, which can be used in double shells for bottom plate seam welding.
