Structural Welding Works as per AWS D1.1 / ASME IX

We are experts in providing Structural Welding Works strictly adhering to internationally recognized codes and standards such as AWS D1.1 (Structural Welding Code – Steel) and ASME Section IX (Welding, Brazing, and Fusing Qualifications). Our commitment to code-compliant welding ensures that all welded steel structures meet the highest levels of safety, integrity, and durability required for critical industrial, commercial, and infrastructural applications.

Certified Welding Expertise

Welding is a vital process in the fabrication and erection of steel structures, directly affecting the strength and longevity of the finished product. Our certified welders, inspectors, and engineers possess the technical proficiency and qualifications necessary to execute complex welding tasks as per project specifications and industry codes.

Key Features of Our Welding Services:

  • AWS D1.1 Compliance: Suitable for structural steel welding in buildings, bridges, industrial plants, and general steel frameworks. The standard covers materials, processes, inspection, and quality requirements ensuring safe and defect-free welded joints.

  • ASME Section IX Compliance: Applicable to pressure vessels, piping systems, and critical components where high-integrity welds are mandatory. Our procedures and welders are qualified to meet the stringent requirements of this code.

  • Welding Process Capabilities:

    • SMAW (Shielded Metal Arc Welding)

    • GMAW/MIG (Gas Metal Arc Welding)

    • FCAW (Flux Cored Arc Welding)

    • TIG/GTAW (Gas Tungsten Arc Welding)

We select the most appropriate welding process based on the material grade, thickness, service environment, and structural function.

Welding Procedure Development & Qualification

Before commencing production welding, we develop and qualify Welding Procedure Specifications (WPS) and Procedure Qualification Records (PQR) in compliance with AWS D1.1 and ASME IX standards. Our welding engineers ensure that all welding procedures are tested and validated for:

  • Base Material Compatibility

  • Filler Metal Selection

  • Joint Design and Fit-Up

  • Preheat & Post-Weld Heat Treatment Requirements

  • Weld Positioning & Technique

Skilled & Certified Welders

All our welders are qualified to AWS D1.1 and/or ASME IX standards through rigorous testing and certification programs. Continuous training ensures they are familiar with the latest techniques, safety protocols, and code updates. This guarantees weld consistency, strength, and defect-free performance across all projects.

Inspection & Quality Assurance

Quality control is integral to our welding operations. We follow a strict Inspection & Test Plan (ITP) that includes:

  • Visual Welding Inspection (VT)

  • Non-Destructive Testing (NDT) such as Ultrasonic Testing (UT), Radiographic Testing (RT), Magnetic Particle Testing (MT), and Dye Penetrant Testing (PT)

  • Dimensional Verification of welded assemblies

  • Weld Hardness & Strength Testing where required

All inspections are conducted by Certified Welding Inspectors (CWIs) to ensure full code compliance and traceability.

Applications of Our Structural Welding Works

  • Structural Steel Buildings & Industrial Plants

  • Bridges, Towers, & Heavy Infrastructure

  • Pipelines, Tanks, & Pressure Vessels

  • Steel Frames, Platforms, & Support Structures

  • Offshore Structures & Marine Applications
