VALLEJO, Calif. — Arcmatic Welding Systems, based at the former Mare Island Navy shipyard, specializes in turnkey, computer-controlled welding systems for heavy-plate applications, including the fabrication of structural steel beams and columns for the institutional construction sector.
Arcmatic systems utilize Versaslag — a patented modular variant of the Narrow-Gap Improved Electroslag Welding process — or a twin-wire Submerged Arc Welding process with metal powder additions that deliver high-deposition rates, cost efficiencies and impact resistance.
The modular mechanical and electrical components of both computer-controlled welding processes can be mounted on several application platforms and units, such as Arcmatic’s dual carriage gantry, which facilitates simultaneous two-weld operations that further increase deposition rates (in excess of 300 lbs per hour) and reduce welding times in the fabrication of structural beams and columns.
“Box columns for buildings generally require four 20-foot-long partial penetration weld seams,” says company founder William Bong. “With our dual carriage gantry welding system, we can weld the two top seams in one single pass.”
