III. KEY COMPONENTS

3.1 Main Frame

The Main frame of the girth welder is constructed of structural steel and square tube members. The sliding

square tube mechanism with locking pins and pin holes is used to adjust the frame height for welding

different sizes of shell plates. The main frame of the girth welder is designed to support 550 lbs (250 kg) of

weight, or enough for two operators.
The frame contains two serrated hardened steel flanged drive wheels manually adjusted to ride tank

diameters down to a minimum of 15' (4.5 m.) The distance between wheel flanges is 1.8" (45mm) [standard]

to accommodate the shell wall thickness.
The machine frame is equipped with a hand railed operator platform with seat; a ladder provides a means

for operator to climb to the roof and access to the electric flux winch and separator tank for flux refill.
Guide wheel assembly at the lower end of the frame also helps to simplify loading and unloading the

machine on to the tank. Canvas curtains offer arc and operator protection in windy conditions.

3.2 Dual Motor Drive

Each single, flanged drive wheel is driven by an individual motor / reducer to provide extra tracking force to

prevent slipping that could cause weld defects. Drive motors are enclosed inside the frame top section with

aluminum panels for good weather protection.

Speeds for both motors are electronically synchronized and governed by a Mitsubishi or ABB inverter for

accurate speed travel.
