The girth welder is an automatic welding machine that straddles the tank plate and is used to complete the circumferential weld joints of a tank. It’s typically used in a single or double-sided configuration. In the single-sided configuration, one operator is required, and welding is performed on one side of the joint. In the double-sided configuration, two operators are needed, and welding occurs on both sides of the weld joint, providing a significant advantage for the root pass in accordance with the API’s requirements.

The use of girth welders will increase productivity by up to 10 times compared to manual completion, with the additional benefit of improved weld quality.
