Certified Industrial Welding
Industrial Welding Division: MIG, TIG, ARC and Spot Welding Across Five Material Grades
Expertise and Experience
Aero Enterprises Unit I Vasai Phata operates a 6-machine welding division comprising 4 multi-process inverter welding units capable of MIG, TIG, and ARC processes and 2 resistance spot welders. The division welds MS IS 2062, SS 304 and 316, GI IS 277, aluminium, brass, and copper across structural weldments, precision thin-gauge assemblies, modular fabrication, and high-volume spot-welded hardware components. Welding at Unit I is not a standalone service. It is an integrated production stage where laser-cut and press-brake-formed components from the same floor are assembled and welded before entering the 7-tank powder coat pre-treatment line. Every weld joint that carries structural load is visually inspected and dye penetrant tested before the component proceeds to finishing. No structural weld joint is concealed under powder coat without pre-coat inspection at Unit I.
Why Our Process Wins
The most common welding failure mode in sheet metal fabrication is not the weld itself. It is the sequence and fixturing decision made before the first arc is struck. A component welded without adequate fixturing distorts during the weld thermal cycle and cannot be corrected after the weld cools without introducing residual stress that reduces fatigue life. At Aero Enterprises Unit I, every welded assembly is fixtured before welding begins. Weld sequence is defined to minimise heat accumulation and thermal distortion. On thin-gauge CR IS 513 below 1.5mm, stitch welding sequences with controlled inter-pass cooling are mandatory. On GI IS 277, ventilation and respiratory protection protocols are enforced because zinc vaporises at welding temperature and zinc fume fever is a direct health risk without extraction. These are not optional procedures. They are the production standard at Unit I.

Verification Protocol
Welding Procedure Specification (WPS) review before every new joint configuration is welded in production. Joint type, fillet size, weld sequence, inter-pass temperature, and post-weld treatment are defined in the WPS before the first arc is struck on a new component.
Pre-weld fixturing verification confirming that all components are correctly fixtured and dimensionally aligned before welding begins. Distortion caused by inadequate fixturing cannot be corrected after the weld cools without introducing residual stress. Fixturing is not optional on any structural or dimensional-tolerance weldment at Unit I.
Visual weld bead inspection on every joint after welding and before any post-weld finishing or powder coat application. Inspection covers bead profile, undercut, overlap, spatter, crater fill, and toe angle on all accessible weld joints. Any joint showing undercut or unfilled crater is re-welded before the component proceeds.
Dye Penetrant Testing (DPT) on structural load-bearing joints and on any joint that will be concealed under powder coat or assembly components after finishing. DPT reveals surface-breaking cracks, porosity, and lack of fusion that are not visible in standard visual inspection. At Unit I, DPT is performed before powder coat application so that all detected defects can be repaired while the joint is accessible.
Spot weld nugget verification on resistance spot welded assemblies using destructive peel test on batch samples to confirm nugget diameter and penetration depth meet the specified joint strength requirement.
Post-weld dimensional check on welded assemblies before finishing. Thermal distortion during welding can shift component dimensions outside assembly tolerance even when individual pre-weld components are within tolerance. Dimensional verification after welding and before powder coat confirms the finished assembly will meet the drawing envelope.
