Learn to write prequalified welding procedures in conformance with AWS D1.1 Structural Welding Code. Follow this step-by-step guide to writing your first prequalified welding procedure today!
Developing welding procedures requires an understanding of all the different essential variables as well as the process of qualifying or prequalifying such procedures.
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 […]

Have you ever been in a situation in which you need a qualified welding procedure immediately? Maybe you just failed an audit and have to halt production until a valid welding procedure is provided. Or maybe you’re just in a hurry to get started with a new job. Regardless of the reason you need the […]
Have you ever seen a welding procedure specification with established amperage ranging from 200 to 550 amps? Or voltage ranging from 21 to 29 volts? Or some other variable with a huge window? This is all too common, but extremely dangerous. Why? Because changes to essential variables beyond that which is reasonable will affect the […]
One of the advantages of using prequalified welding procedures is that you can save a lot of time and money because they are exempt from testing. This means you don’t need to perform any destructive or nondestructive testing. You simply follow the requirements of AWS D1.1 and you can write a prequalified welding procedure and […]
