Continuous learning is something that is very important for both personal and professional development. This applies to all industries and to all positions. The welding industry, as many of its counterparts, is challenged with a workforce that is lacking the skills necessary to do the job. This is driven by the increased demand for welders, […]
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!
Welding in cold temperatures poses two critical challenges. First, the brutal conditions welders must endure and second, the performance of steel structures in cold temperatures. Many times we forget about the former by focusing too much on the latter. If you ever get a chance to talk to welders that have welded in both extreme […]
Who determines what size a weld should be? This is a question we ask many of our customers. And we never seem to get a straight answer. In a perfect world, the design engineer should specify all weld sizes and clearly communicate this through welding symbols on the print. But that is hardly ever the […]
In today’s article we’ll be discussing a critical aspect of welding which is crucial in ensuring the safety and long useful life of structures. When engineers conduct a fitness for service analysis of structures they are looking for flaws. These flaws may be cracks, loose bolts, deformations, rust damage (thinning of structural members) and other […]
There are four types of loading experienced by welds and welded structures. These types of loading are a function of the strain rate (the rate at which deformation occurs in a material due to an applied load) and the number of loading cycles experienced by the welded member. The 4 types of loading are: Static […]
Weld failures happen all the time. Some are more serious than others in terms of cost and potential for property damage and bodily harm. If a weld failure is considered serious it typically gets a lot of attention. Forensics labs and industry experts get called to determine the root cause of the failure. It may […]
Distortion caused by the heating and cooling cycles of welding is extremely problematic. It can place structures out of dimensional tolerance creating costly rework. In some cases parts need to be scrapped. Understanding the causes of distortion and the properties of the metal being welded are an absolute necessity for those managing welding operations. There […]
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 […]
If you own, run or work at a welding facility you have undoubtfully had to troubleshoot bad welds. Troubleshooting is necessary in order to solve problems, but if you do not have a clear methodology or process for troubleshooting it can be a huge source of downtime. To properly troubleshoot bad welds, we must have […]
