Absolute Integrity in Every Weld seam

At Openex, welding is both an art and a strictly engineered science. When dealing with extreme-scale pressure vessels, massive dump bodies, or 100-ton offshore components, the structural integrity of every weld must be flawless. Operating under strict global maritime, pressure, and structural codes, we deliver certified manual, semi-automatic, and robotic welding at a massive scale.

Heavy Capabilities

Heavy Structural Welding

Geared entirely for large scale, our manual and semi-automatic welding departments can handle weldments up to 250 Tons. By deploying extreme-penetration Submerged Arc Welding (SAW), massive turning rolls, and deep-groove TIG root passes, we fabricate ultra-thick components perfectly.

› SAW & FCAW/MIG: Rapid, pure deposition for thick vessels.
› TIG (GTAW): Critical defect-free root passes on exotic metals.
› Thick Plates: Capable of joining extremely thick steel components.

High-Volume Automation

Robotic Welding Solutions

When projects demand hundreds or thousands of identical parts—like trailer chassis, heavy equipment linkages, or recurring transit frames—human variability must be eliminated. Our robotic welding cells ensure perfect cosmetic beads and identically defect-free mechanical properties, cycle after cycle.

› Cost & Speed: Eliminates human fatigue, significantly lowering costs on runs.
› Multi-Axis Positioners: Robots sync perfectly with rotary tables for full 3D access.
› Seamless Traceability: Robotic data logs guarantee continuous weld parameters.

Beyond the Arc: NDT & Stress Relief

A welded seam is only acceptable if it passes stringent Non-Destructive Testing (NDT) and post-weld metallurgical balancing. Openex possesses these critical auxiliary capabilities strictly in-house.

🔍 NDT Inspection

Level II & III technicians performing Ultrasonic Testing (UT), X-Ray/Radiographic Testing (RT), and Magnetic Particle testing directly adjacent to the weld cells.

🔥 Heat Treatment

Our massive internal heat treatment furnaces administer critical Post Weld Heat Treatment (PWHT) to completely relieve structural stresses preventing fractures.

🔪 Profile Cutting Prep

A perfect weld starts with the perfect joint groove. Our advanced multi-axis plasma bevelling equipment creates precision V, X, Y, and K joint preparations prior to fit-up.
