Automatic Vertical Seam Welding Machine NAEC Automatic
Vertical Seam Welding Machine is designed for Vertical Seam Welding
of storage tank with top-to-bottom or bottom-to-top
construction method. The machine adopts servo systems and
closed loop control welding carriage to control welding gun's
automatic stepping up speed to guarantee welding pool stability,
thus to finish automatic welding of vertical welding seam of
big tank, blast furnace or tower. The main characteristic is
that water cooling copper sliding block forces single pass welding
seam, which greatly improves the welding quality and welding
efficiency and reduces operator's work intensity. Features:1.
Suitable for both bottom-to-top and top-to-bottom construction
methods.2. Adopt sub-arc welding technology.3. Support
customer to finish one tank body construction within one month by
NAEC advanced solution.4. Automatic welding efficiency is 15-40
times of manual.5. First X-ray qualification rate: ≥99.5%.6.
Mechanical performance meetslow-temperature impact test
requirement.7. Project implementation follows API650,ASME, AWS and
other international standards.Automatic Vertical Seam Welding
