Butt/Corner Seam Welding MachineNAEC Automatic Butt/Corner Seam Welding System can realize automatic welding work of various welding seam, including butt joint welding seam, overlapping joint butt/corner welding seam, T-type butt/corner joint seam, etc.
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.
1. Suitable for both bottom-to-top and top-to-bottom construction methods.
2. Adopt sub-arc welding technology.
4. Support customer to finish one tank body construction within one month by NAEC advanced solution.
5. Automatic welding efficiency is 15-40 times of manual.
6. First X-ray qualification rate: ≥99.5%.
7. Mechanical performance meets low-temperature impact test requirement.
8. Project implementation follows API650, ASME, AWS and other international standards.
