Girth Welders

Reduce Field Storage Tank Welding Time by 40%

Bug-O Systems offers Automatic Girth Welders for tank fabrication applications. They are convertible for both bottom up and top-down construction. Bug-O Girth Welding Machines are also capable of being used as a pair to construct a dual-sided girth welder. Special models can be built per the customer’s request.

Unlike other girth welding machines on the market, the BGW (Bug-O Girth Welder) Series 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 reducing weld defects.

The models run directly on the tank and carry the operator, eliminating the need for scaffolding while ensuring operator comfort and safety. The Automatic Girth Welders are applicable for top-down or bottom-up constructed single or double-wall storage tanks, due to their modular design.

They are designed for internal and external welding. There are four standard units and our design allows us to offer custom-built units for special applications.

Features:

Dual drive motor system
Efficient flux recovery system
Integrated control panel
Laser site guide
Ergonomic operator cabin
Adjustable weld head and flux belt support system

What Is a Tank Welding Machine?

A tank welding machine is specialized equipment used to join sections of field-erected storage tanks. Designed for precision and durability, these machines streamline the construction of oil, gas, and water tanks by automating weld processes and minimizing manual labor. Bug-O Systems offers tank welding solutions that improve productivity and ensure consistent weld quality across every project.

Benefits of Using an Automatic Girth Welding Machine

Automatic girth welding machines are designed to weld horizontal seams on cylindrical tanks with minimal operator input. Bug-O’s modular systems eliminate common inefficiencies found in manual welding.

Reduces total weld time by up to 40%
Improves arc-on time and lowers defect rates
Eliminates the need for scaffolding
Enhances operator safety and comfort
Ensures consistent, high-quality welds on every pass

What Makes an AGW Welding Machine Unique?

An AGW (Automatic Girth Welder) machine is purpose-built for girth seam welding on storage tanks. Bug-O’s AGW systems feature dual-drive motors, ergonomic operator cabins, and modular designs that support both internal and external welds.
