Developing a Welding Procedure Specification (WPS) involves much more than selecting amperage and voltage—it requires a structured approach to ensure weld quality and consistency. The process begins with understanding the base metal’s properties and how it responds to heat, followed by selecting the most suitable welding process for quality and productivity. Choosing the correct filler metal and joint design are equally critical, as both influence weld strength, cost, and efficiency. Proper control of preheat and post-weld heat treatment (PWHT) helps manage metallurgical changes that prevent cracking or distortion. Finally, setting appropriate welding variable ranges ensures balance between quality and productivity, resulting in a reliable, code-compliant welding procedure.

Ever wondered why your fabrication shop struggles with welding procedure audits? This post dives into the 11 most common reasons shops fail to meet welding procedure conformance, from a lack of accessible WPS documents to issues with equipment and management enforcement. Discover critical insights for welding engineers, supervisors, and welders alike, helping you identify and fix these pitfalls before your next audit. Learn how proactive measures can significantly improve your weld quality and ensure seamless compliance.

ASTM A514 (T-1) is a high-strength, quenched and tempered steel known for its exceptional yield strength and use in heavy-duty structural applications like cranes and bridges. Its martensitic microstructure, while providing strength, makes it susceptible to cracking if not welded correctly, particularly in the heat-affected zone. Successful welding requires careful selection of high-strength, low-hydrogen electrodes, precise adherence to preheat and interpass temperature guidelines, and diligent control of hydrogen sources. Unlike many steels, AWS D1.1 requires qualification by testing for A514, emphasizing the need for rigorous procedures to achieve sound and reliable welds.

This post provides answers to frequently asked questions regarding the "280 Prequalified Welding Procedures for Stainless Steel" product. It addresses common inquiries from customers about the digital format, permissible uses for CWIs, distinctions between qualified and prequalified procedures, and the rationale behind the product's affordability. Additionally, it clarifies compliance with AWS D1.6, modification flexibility, and how included guides facilitate proper use and customization of these welding procedures.

Weld failures in the field often expose deeper systemic issues within a company's welding operations, leading to severe consequences like litigation and financial distress. Many companies mistakenly rely on past success as justification for lacking proper quality control, including welding procedure and welder performance qualifications, and robust inspection processes. When failures occur, the absence of crucial documentation complicates failure analysis and almost guarantees liability. This post emphasizes the critical need for proactive measures like developing welding quality standards, qualifying procedures and welders, and implementing stringent inspection processes to prevent catastrophic failures and ensure long-term structural integrity.

Rework in welding is a massive productivity killer—tripling labor, wasting material, and slowing down production. While there are many causes, three simple fixes can drastically reduce rework: stop overwelding, use properly qualified welding procedures, and maintain your equipment. In this post, we dive into how these small changes yield big results—lowering costs, improving quality, and increasing efficiency across the shop. If you're tired of grinding out the same welds twice, this is the post for you.

Want to boost welding productivity? Increasing your deposition rate is one of the most effective ways—but only if done right. This post explains the difference between melt-off and deposition rate, how higher deposition leads to faster travel speeds (and real time savings), and the common mistakes that sabotage these gains. Learn how to avoid costly errors, why simply turning up the amps isn’t enough, and how training and proper welding procedures can unlock major efficiency improvements in your shop.

This blog post concludes a series on developing welding procedures by discussing the crucial topic of qualification. Qualification involves performing both destructive and non-destructive tests to ensure a procedure can produce sound welds, typically following the requirements of specific codes like AWS D1.1. An alternative to this rigorous testing is prequalification, which allows the user to forgo testing if all the requirements of the applicable code's prequalification clause are met. Regardless of the method, the document emphasizes the importance of verifying and documenting the suitability of all developed welding procedures for future reference and quality assurance.

Amperage, voltage, travel speed, and other key variables are crucial for creating a robust welding procedure that ensures sound and high-quality welds.Blog Post Summary This blog post explains the importance of key welding parameters when developing a welding procedure specification. It details how amperage (current) directly influences weld penetration and productivity, while voltage primarily affects bead shape and width. The post also highlights that travel speed is critical, as it impacts weld size, heat input, penetration, and overall weld quality. Additionally, it covers the significance of travel and transverse angles, noting their effects on weld shape and potential for defects. Finally, the post emphasizes the often overlooked but critical role of Contact Tip to Work Distance (CTTWD), explaining how it can drastically alter amperage and potentially lead to a non-compliant or defective weld if not properly controlled.
