Product Description

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 meets
low-temperature impact test requirement.
7. Project implementation follows API650,
ASME, AWS and other international standards.
