Consisting of welding manipulator, welding rotator and submerged arc welding device, the longitudinal welding center is controlled with trinity. Featuring high welding efficiency and nice welding seam shape, the submerged arc welding technology is often employed to welding the steel plate with thickness of medium size. The equipment can be widely used for pipe welding in petrochemical industry and in the fields of shipbuilding, metallurgy and boiler.

1. This series of welding manipulator has several types for choosing: fixed type, fixed with rotating type. moving with rotating type. etc.
2. The welding manipulator can be 3 in 1 controlled together with welding power. welding rotator or positioner according to users' requirement.
3. The column and boom adopts welding parts which adopts tempering post welding. then carry out tine machining which can ensure higher precision requirement.
4. Boom adopts square rail, horizontal stretch and retract adopts gear and rack transmission with high precision and stability.
5. There's safety falling protective device for boom elevating, which can effectively prevent the boom falling problem occurs.
6. There's cross slider for the welding torch equipped in front of the boom to realize welding torch cross adjust for going up. down, left, right.
7. There's ladder on the column, which is convenient for maintenance. Also it is equipped with the platform which is convenient for placing the welders.

It can be equipped with wireless remote control box according to users' requirement. which is convenient for operation.
