Fabricated Components & Structural Assemblies
Certified heavy structural fabrication, robotic and semi-automatic multi-process welding, post-weld heat treatment (PWHT), and micron-level CNC machining for mission-critical global OEMs.
Engineered to Withstand Extreme Dynamic & Static Mechanical Stresses
ER Industries manufactures high-integrity heavy fabricated assemblies, welded sub-assemblies, and skid frames for defense, energy, infrastructure, and heavy machinery OEMs. Our turnkey process integrates high-definition plasma cutting, certified ASME Section IX welding, stress relief, and post-weld multi-axis CNC machining.
Qualified WPS and PQR procedures for GMAW (MIG/MAG), GTAW (TIG), and SAW (Submerged Arc) welding.
Controlled soaking furnaces eliminate locked-in thermal stresses, preventing distortion and micro-cracking.
Large-travel machining centers machine critical bearing bores and flange faces after stress relief to ±0.01 mm tolerances.
