Tank Welding LLC specialize in custom built to order automatic tank welding machines for LNG & flat bottom tanks. We have multiple standard site proven Automatic Girth Welder designs (AGW) 3 O’clock Welder designs. Single pass gas shielded EGW (Electrogas Welder), single pass self shielded VUP / vertical UP Welders & AVW / multiple pass Automatic Vert Welders, Automatic Vert Buggy, Shell Buggy, Tank Jacking Equipment and complete Tank Jacking systems, automatic curved plate welders for pressure vessel / sphere / digester welding. This line of equipment is built with your choice of USA made Lincoln or Miller welding systems. The AGW travel is powered by top of the line twin German engineered inverter controlled drive motors.
Engineering and Custom Solutions
As a leading custom tank welding equipment supplier, Tank Welding LLC is dedicated to advancing the storage tank construction industry through engineering innovation. We recognize that no two projects are identical, which is why we specialize in designing, engineering, testing, and manufacturing automated systems tailored specifically to your unique job site parameters. Your operations might require standard setups, low-heat input multi-pass configurations, specialized alloy adaptations, or custom structural framing.
Whatever the challenge, our equipment handles the rigorous demands of global energy infrastructure, LNG storage, and flat bottom tanks. Our specialized, field-proven lineup includes state-of-the-art single-sided Automatic Girth Welders (AGW), dual-sided girth systems, Electrogas Welders (EGW), and specialized automatic curved plate solutions.
To provide the highest standards of reliability and durability, our equipment integrates industrial-grade components from premier brands, allowing you to optimize your production workflow with high-performance welding machines USA contractors rely on for execution.
Versatile Equipment Built for Global On-Site Demands
Maximizing productivity on-site requires field-erected tank equipment that adapts to tight spaces and complex designs. Our versatile fleet features narrow-frame automatic vert buggies, tracking systems.
By combining decades of hands-on global field experience with ongoing technological developments, we continuously refine our designs based on direct feedback from welders, foremen, project managers, and superintendents.

Frequently Asked Questions
What types of tank construction projects can your automated systems support?
Our specialized fleet is built to handle a massive range of field-erected applications across multiple industries. We provide tailored solutions for global energy infrastructure, liquid natural gas (LNG) storage tanks, and flat bottom oil tanks, and specialized vessels.
How does Tank Welding LLC ensure the reliability of its machinery on remote job sites?
We understand that downtime is incredibly costly, which is why we build our equipment using only premium, industrial-grade components. Every single unit undergoes rigorous testing, stress simulation, and quality control checks before leaving our partner companies facility to ensure it stands up to harsh field conditions.
Can your equipment be customized for specific project layouts or welding procedures?
Yes, as a dedicated custom tank welding equipment supplier, customization is our core focus. We regularly modify and engineer our systems to match specific low-heat input multi-pass configurations, unique tank diameters, tight scaffolding constraints, and challenging environmental factors.
What safety and operator features are integrated into the shell buggy and automatic welders?
Safety is deeply integrated into our engineering process. Our automated welding systems, vertical buggies, and specialized shell buggy units feature ergonomic operator cabs, robust fall-protection integration, stable tracking mechanisms, and accessible emergency stop systems to protect your crew on every seam.
