We frequently receive questions regarding the preheating, welding, and post-weld heat treatment of ASTM A514 and other quenched and tempered steels. If you’re working with these materials, the following guidelines will be extremely helpful for welding this steel and avoid cracking or other problems. Metallurgy, Uses, and Welding Challenges of ASTM A514 ASTM A514, often […]

No. The welding procedures are provided as digital files (PDF) and are available for immediate download. The user has the option to print the files as many […]
We are excited to officially release our latest collection: 280 Prequalified Welding Procedure Specifications for Stainless Steel As we mentioned during our preview last week, these welding procedures have been developed and prequalified in conformance with AWS D1.6/D1.6M Structural Welding Code – Stainless Steel. ORDER HERE! ORDER HERE! These welding procedures were put together for: […]
AWS D1.6 is the Structural Welding Code for Stainless Steel. Its primary concern is with the structural integrity of weldments and not with resistance to corrosion, creep or sensitization. As a matter of fact, the word “corrosion” appears only eight times in the 9 clauses of AWS D1.6. Requirements for these concerns are the responsibility […]
When a weld fails in the field, the consequences can be catastrophic. Our experience as welding engineering consultants has shown us that such failures often expose deeper issues within a company’s welding operations. These situations can lead to fears of additional failures in other products or structures, potential harm or fatalities, litigation, and even bankruptcy. […]

When writing a welding procedure one of the most critical steps is selecting our welding parameters. This means determining the appropriate amperage and voltage as well as other critical aspects that the welder must adhere to such as travel speed and travel and work (transverse) angles. What follows is an explanation as to the importance […]
Selecting the best welding process is a critical step in developing a welding procedure that attains the desired quality and optimizes productivity. Many times we look for the welding process that can give us the highest deposition rate to optimize productivity. However, every welding process has limitations. For example, submerged arc welding (SAW) has extremely […]
One of the most common questions we get around the topic of welding procedure qualification is regarding the differences between qualified and prequalified welding procedures. The main question is typically: is one better than the other? Before we answer this question, let’s first discuss the need for qualified, or prequalified, welding procedures. If you have […]
If you work with AWS D1.1 you are probably familiar with the use of prequalified welding procedures. The use of prequalified WPSs provides many benefits to the fabricator, one of which is costs savings due being exempt from having to perform costly testing to qualify the welding procedure. However, if you are looking to save […]
