Automatic Girth Welder

Description：

ABK Electric offers the Automatic Girth Welder for tank fabrication applications. Unlike other girth welders on the market, ABK GSAW comes standard with a Dual Drive System and other features unique to our machines. This self-propelled submerged arc welding system can reduce field storage tank welding time by 40% by increasing arc on time and reduce weld defects. The models run directly on the tank and carry the operator, eliminating the need for Scafolding while ensuring operator comfort and safety. The girth welder, due to their modular design, are applicable for top down or bottom up constructed single or double wall storage tanks. They are designed for inside and outside welding. There are four standard units and our design allows us to offer custom-built units for special appllicaions.

Main Parts

A) OPERATER

The main frame is mainly composed of transverse welding operation and welding steel structure

Suit upside-down tank build

Suit min dia5.0m

Suit board 1.5m~2.5m

B) DOUBLE DRIVE UNIT

AC double drive design of the welder can be full circle around the tank when the tank was walking on the flawed, feeding, double drive power is more stable, and better adapt to the repair of defects, and more easy to use than the single drive.The programmable frequency drive equipment

C) WELDING POWER AND FEEDER

The welding system with the LINCOLN NA3 controller and the wire feeding machine, comprising wire disc shaft corresponding to the wire reel, can be loaded with single plate submerged arc welding wire below 27.2kg.

The welding power supply: LINCOLN DC600
