Certified welders across MIG, TIG, laser and stud welding cells — structural steel to AWS D1.1, sheet metal to D1.3, stainless to D1.6 — for transformer tanks, cabinets, bus duct, substation structures and everything else FabTek builds.
Power-system fabrication spans three welding worlds. A substation dead-end structure is heavy structural steel welded to AWS D1.1. A transformer cabinet is thin sheet welded to D1.3 with a finish that will show every defect after powder coat. A 4X stainless enclosure or a sanitary conveyor is welded to D1.6 with ground and polished seams. A transformer tank has to hold oil under vacuum. Most shops are qualified for one of those; FabTek's welding cells are qualified for all of them, because the products we build require all of them.
The department is organized as cells — structural welding with positioners and manipulators for heavy weldments, sheet-metal cells for cabinets and enclosures, a stainless cell kept clean of carbon contamination, a laser welding cell for thin material and long seams, and stud welding for hardware — with certified welders, written weld procedures and documented inspection under our ISO 9001:2015 system. Every weldment carries the welder ID and inspection record for the customer's file.

Keeping structural, sheet-metal and stainless welding under one roof is only useful if each is done right, and that means separating them. FabTek runs a stainless cell with its own tooling and abrasives so carbon contamination never reaches a 4X enclosure; runs structural welding on positioners so a full-penetration joint is welded in position rather than overhead; and runs sheet-metal cells with the fixtures and heat control that keep a cabinet door flat. Our spec sheet on which welding code applies explains how the three differ, and ISO 9001 and AWS-certified welds covers the documentation.
