- Prepare and Issue of WPS, PQR and Welder Qualification Certificate duly certified by qualified inspector.



Ensures Quality and Consistency

A properly developed WPS ensures that welding operations produce consistent and high-quality results, reducing defects and rework.


Meets Legal and Code Requirements

Many industries require WPS documentation to comply with national and international codes, helping avoid legal issues and project delays.


Improves Efficiency

Well-defined welding procedures streamline operations, improve workflow, and reduce the risk of errors, ultimately saving time and cost.

Safety Assurance

By adhering to a WPS, workers follow best practices, minimizing risks associated with poorly executed welding and ensuring workplace safety.

Ensuring high-quality, consistent, and safe welding practices across a wide range of industries. 

FAQ

A Welding Procedure Specification (WPS) is a formal document that provides detailed instructions for a specific welding process, including parameters like the welding technique, materials, position, and the settings for the welding equipment. It ensures that welding is done consistently, safely, and in compliance with industry codes and standards.

    WPS services are crucial for:
    • Code Compliance: Ensuring that your welding procedures meet industry codes (e.g., AWS, ASME, ISO).
    • Quality Control: Standardizing welding processes to ensure consistency and quality across all welding operations.
    • Safety Assurance: Preventing defects that could compromise structural integrity or create safety hazards.
    • Documentation: Providing necessary documentation for inspections, audits, and regulatory compliance.
    A complete WPS includes several key elements:
    • Base Material: Type and grade of the material being welded.
    • Filler Metal: Specifications for the filler material, including type, diameter, and brand.
    • Welding Process: The welding technique used (e.g., TIG, MIG, Stick).
    • Joint Design: Details about the joint configuration and welding positions (flat, horizontal, vertical, overhead).
    • Preheat and Interpass Temperature: Temperature requirements to prevent cracking or distortion.
    • Shielding Gas: Type and flow rate of shielding gases used.
    • Welding Parameters: Voltage, amperage, travel speed, and other process controls.

WPS documents are developed based on:

  • Welding Codes and Standards: They are created according to industry standards like AWS, ASME, API, or ISO.
  • Material Specifications: A WPS must match the materials being welded (e.g., steel, aluminum, alloys).
  • Process Requirements: The WPS defines which welding processes are appropriate for the material, joint configuration, and required strength.
  • Testing: Some WPSs require qualifying tests (Procedure Qualification Records or PQR) to verify that the procedure produces acceptable results.
  • WPS (Welding Procedure Specification): Provides the guidelines and parameters for a welding process.
  • PQR (Procedure Qualification Record): A document that records the results of testing conducted to verify that the WPS works effectively. It is the proof that the WPS is valid and can produce acceptable welds under the specified conditions.

    • A WPS is typically valid as long as the conditions outlined in it (e.g., materials, welding processes) remain unchanged. However, if the materials, processes, or codes change, a new WPS or update to the existing WPS might be required. Requalification is also necessary if there are changes in the production environment or welding personnel.

    WPS services help ensure compliance with industry codes and regulations (e.g., AWS, ASME, ISO), which is crucial for project approvals, inspections, and audits. Well-documented and well-executed WPSs also provide a traceable record of welding procedures, which is important for quality assurance, legal purposes, and ensuring consistent results.
