It has features as following:
1.Adopt sub-arc welding technology;
2.Applicable to bottom-to-top tank erection, hanged on shell top;
3.First X-RAY qualification rate above 99%;
4.More suitable for erection of tanks larger than 30M;
5.Two welding systems, high efficient welding.
Combining years of experience in serving of large storage tank and other vertical tank projects, AUTO researched and developed the new generation of Automatic Sub Arc Girth Welding Machine with No-gauging System (AGW-I/II with no-gauging system) based on customer's requirements. It owns characteristics of high efficiency, superior root welding quality, stable performance, saving of consumables and no need of back gauging step. It has been the great helper for users' construction project.
Double Sided Automatic Sub-Arc Girth Welding Machine (AGW-II) is a girth seam welding machine developed by NAEC with frontier technology. It adopts special welding and control communications technology which can realize welding two sides girth seams at the same time. It helps customers to achieve the highest welding speed and welding quality.
