Introduction of Girth welding machine

Our tank welding machine has been successfully sold to over 20 countries worldwide and used on over 1000 project sites. We take pride in offering top-quality machines with exceptional after-sales service. Our welding machine can be used for single side, double side, and bottom plate/corner welding for crude oil, LNG, fuel, water tanks, and can be used for horizontal and vertical seams. Our machines have been sold to various countries such as UAE, Saudi Arabia, Oman, Bahrain, Kuwait, Cameron, Sudan, Egypt, Senegal, Nigeria, Zambia, Ethiopia, Vietnam, Indonesia, Malaysia, Philippines, Singapore, Mexico, Mongolia, and Russia.

Key Components of the Girth Welding Machine

The main frame of the girth welder is made from structural steel and square tube members. The erection method is bottom-to-top and the minimum diameter for welding is φ5.0m. The shell width for bottom-to-top welding is 1.5-3.0m.

Major component of Girth welding machine

A. The main frame of the girth welder is made from structural steel and square tube members. The erection method is bottom-to-top and the minimum diameter for welding is φ5.0m. The shell width for bottom-to-top welding is 1.5-3.0m.

B. Dual Motor Propulsion

Thanks to the dual AC motor configuration, the equipment can travel smoothly around the entire circumference of the tank, even if the fit is not perfect or there are uneven surfaces. This feature will save time and costs as it reduces the need for repairing weld defects. A single, easily programmable frequency inverter controls both motors.

C. Power Source and Wire Feeding System

The welding equipment being provided includes the Miller HDC1500DX control, the RAD400 weld head with nozzle and wire rolls, and a wire reel weighing 27.2kg. The power source is the SubArc DC800,CE, and the welding progress control is the HDC1500DX. The RAD400 wire feeding system is also included.

D. Power Source and Wire Feeding System

The welding equipment being supplied includes the Lincoln NA-3S control, the weld head with nozzle and wire rolls, and a wire reel weighing 27.2kg. The power source is the DC600. Both the welding progress control and wire feeding system are the NA-3S.

E. Control Panel

The control panel of the AGW machine houses the electric travel inverter drive and control relays. It allows for unified control of all the girth welder’s accessories, including the flux vacuum, 220V single phase auxiliary outlet, lamp, and flux winch. The panel contains all the necessary control switches and knobs, such as the speed control potentiometer, direction switch, full speed travel switch, and emergency stop button.

F. Flux Retrieval System

Flux hopper holds up to 80kg and features a rotating flux dam.

G. Flux Lifting Hoist

This hoist can handle up to 160kg, lift to a maximum height of 30m, and has a lifting speed of 15m/min.

H. Cable Sets

Welding cable measures 120mm2×60m, control cable measures 10p×2.5mm2×60m, power cable measures 3p×4mm2×60m, and ground cable measures 120mm2×5m.
