Since 1967, Dimetrics® has been a pioneer in the development of orbital welding equipment for tube and pipe. Incorporated into the Liburdi Group of Companies in 1997 and infused with orbital products acquired from the Hobart Brothers Company Advanced Welding Group, Liburdi Dimetrics® continues to be a leader in this field. Offering an extensive range of GMAW, GTAW, and Hot Wire orbital weld heads and power supplies, Liburdi Dimetrics® excels at the precision welding of tube and pipe, medical devices, bellows, molds, and automotive components.

In the year 2000, Liburdi Dimetrics® incorporated products and technologies acquired from both Merrick Engineering and Weldline Automation into the Merrick Weldline® product family of industrial welding equipment.  Updated and enhanced versions of Merrick's® MicroPAW® 20 & 100 Micro-Plasma Welding Systems and Automated Welding Lathe, as well as Seamers, Rotary Positioners and Turning Rolls designed by Weldline® are now available under the Merrick Weldline® label.  In addition, custom industrial welding systems are being designed and built for applications in fields such as power generation, ship building, medical, electronics, automotive and aerospace.
