Since 1986, Welder Testing Inc. has been the trusted leader in developing Qualified Welding Procedures (WPS & PQR) for a wide range of industries. Whether you need to create a Welding Procedure Specification (WPS) to meet code requirements or validate it with a Procedure Qualification Record (PQR), our team of experts ensures your welding procedures comply with AWS, ASME, and API standards.
At Welder Testing Inc., we understand that qualifying a welding procedure is a critical step in ensuring compliance, efficiency, and cost-effectiveness. With decades of experience, our team of welding experts guides you through the entire process, helping you meet industry standards such as ASME Section IX, AWS D1.1, and more. Our expertise eliminates guesswork, reduces costly errors, and optimizes your welding procedures for success.
A Welding Procedure Specification (WPS) is a formal document that outlines the detailed welding process to be followed in order to achieve a sound weld that meets all applicable industry standards. The purpose of a WPS is to ensure consistency, repeatability, and compliance across welding operations, helping fabricators, manufacturers, and contractors maintain quality control and regulatory adherence. It outlines all the essential variables necessary to produce a structurally sound and code-compliant weld, including:
Specifications for the types and grades of metals to be welded, ensuring compatibility with project requirements.
Identification of the appropriate process, such as Submerged Arc Welding (SAW), Shielded Metal Arc Welding (SMAW), Gas Tungsten Arc Welding (GTAW), Gas Metal Arc Welding (GMAW), or Flux-Cored Arc Welding (FCAW).
Description of the joint configuration, including groove angles, root openings, and fit-up tolerances.
Selection of welding consumables, including electrode classifications and filler wire specifications.
Guidelines for controlling the heating and cooling of materials to prevent defects.
Specification of welding positions or weld progression.
Identification of gas mixtures and flow rates used for specific welding processes.
Instructions for travel speed, weaving patterns, and arc control.
Ensuring weld integrity through RT, UT, MT, and PT inspections, meeting industry standards for precision and compliance.
At Welder Testing Inc., we recognize that every project is unique. Our team works closely with clients to develop custom WPS that align with their specific project requirements and industry demands. Whether your operations require specialized materials, unique joint configurations, or strict regulatory compliance, we have the expertise to create tailored solutions that meet your needs.
Our seamless WPS development and qualification (PQR) process includes:
Understanding your project’s welding requirements, materials, and applicable codes.
Crafting detailed welding procedures based on industry best practices and compliance requirements.
We conduct a welding test based on the WPS and perform necessary destructive and non-destructive testing (e.g., tensile, bend, impact, radiographic testing) to ensure compliance.
Upon successful qualification, we provide full documentation of the WPS & PQR for regulatory audits and inspections.
Welder Testing Inc. ensures a smooth and efficient WPS qualification process, helping your business stay compliant while optimizing welding quality and performance.
Navigating Complexity:
Welding codes contain intricate rules regarding essential variables, testing, and documentation. Our experts have an in-depth understanding of ASME IX, AWS D1.1, and other codes, ensuring full compliance.
Avoiding Non-Compliance:
Misinterpreting codes can lead to failed qualifications, wasting time and money. We prevent errors that could result in rework or rejection.
Selecting the Right Parameters:
We use practical knowledge to choose welding parameters (e.g., amperage, preheat, filler metals) that work efficiently the first time.
Material and Process Expertise:
We tailor WPS parameters to match specific material behaviors and process limitations, ensuring an efficient and effective procedure.
Increased Efficiency:
We help avoid overly conservative or unrealistic parameters, reducing the risk of test failures and requalification.
High-Quality Welds:
Our advisors oversee the welding process to produce defect-free test coupons, ensuring successful mechanical testing.
Precise Variable Control:
We ensure essential variables such as welding position and heat input are correctly adhered to, avoiding disqualification.
Proactive Problem-Solving:
We anticipate and mitigate issues such as distortion in thin materials, preventing failures before they occur.
Precision in Data Collection:
Recording precise welding data (e.g., amperage, voltage, travel speed) is essential for a successful PQR. We ensure the correct tools and methods are used.
Essential Variable Tracking:
We ensure critical parameters like preheat temperatures and shielding gas compositions are properly monitored.
Reliable Documentation:
Our systematic approach to logging data ensures traceability and reduces disputes or rework.
Expert Test Selection:
We determine the appropriate mechanical and non-destructive tests required by industry codes, ensuring compliance without unnecessary testing expenses.
Proper Specimen Preparation:
Our team ensures test specimens are cut, machined, and prepared according to specifications, avoiding invalid test results.
Interpreting Results:
Our experience allows us to assess test failures accurately, identifying whether they stem from procedural flaws or external factors.
Error-Free PQRs:
We ensure your Procedure Qualification Record (PQR) is accurately completed, aligning with industry standards like ASME IX QW-483.
Effective WPS Development:
We convert PQR data into a practical and usable WPS, ensuring compliance while maximizing flexibility.
Audit-Ready Paperwork:
We prepare all necessary documentation to withstand audits and certification reviews, including ASME Authorized Inspector sign-offs.
Preventing Test Failures:
By ensuring proper parameter selection and test execution, we help avoid costly failures that can result in wasted materials and lab fees.
Streamlining the Process:
We leverage prequalification options and existing PQRs to reduce unnecessary testing and accelerate approval.
Meeting Project Deadlines:
Our efficient approach keeps the qualification process on schedule, ensuring compliance without delays.
Tailored Solutions:
Our advisors specialize in multiple industries, including oil and gas, structural steel, aerospace, and pressure vessel manufacturing, ensuring your WPS meets service-specific demands.
Advanced Problem-Solving:
We address unique challenges such as welding dissimilar metals or extreme service conditions, optimizing procedures for durability and reliability.
A WPS is a formal document outlining the welding process, including materials, and techniques, ensuring weld quality, consistency, and compliance with industry standards.
A certified WPS ensures code compliance, consistent weld quality, and regulatory approval for your projects. Many industries, including construction, oil & gas, shipbuilding, and aerospace, require a WPS to pass inspections, prevent defects, and maintain safety standards.
The most common reason that a company needs a WPS is that they are required to follow a construction code that requires the use of a qualified welding procedure for any welding being performed in accordance with the code. Just about all real construction codes have such a requirement.
A Welding Procedure Specification (WPS) is a set of instructions that outlines the essential variables for producing a code-compliant weld. A Procedure Qualification Record (PQR) is the documented proof that the WPS has been tested and validated through destructive and/or non-destructive testing. The WPS guides welders, while the PQR confirms that the procedure is capable of producing sound welds.
