-
TIG / GTAW (Gas Tungsten Arc Welding)
High-precision, clean welds with excellent control of heat input—ideal for thin sections, stainless, and aluminum, and for critical root passes. Low spatter; slower but highest cosmetic and metallurgical quality. -
MIG / GMAW (Gas Metal Arc Welding)
Wire-fed, fast, and efficient with good deposition rates. Great for general fabrication and production runs on carbon steel and stainless where speed and consistency matter. -
FCAW (Flux-Cored Arc Welding)
High deposition and strong penetration for heavy plate and structural work. Available in gas-shielded or self-shielded variants—reliable outdoors and in less-than-perfect conditions. -
SMAW / MMA (Shielded Metal Arc / Stick)
Versatile and portable for site work and repairs. Tolerant of mill scale and variable fit-up; suitable for all positions and tight access.
Capabilites
-
Shop & field welding: all positions (1G–6G / 1F–6F) for structural steel, skids, pipe spools, tie-ins, and repairs.
-
Materials & processes: carbon/stainless steel and aluminum using TIG/GTAW, MIG/GMAW, FCAW, SMAW/MMA, and plasma (welding & cutting).
-
