We all know welding fumes are bad for your health. Companies that do a lot of welding are paying special attention to this matter and trying to create better working environments not just for welders but for everyone in the shop. Has your company taken any steps to reduce or control fume generation? In this […]
Selecting the filler metal should not be a trivial matter. The easy way out is to select a filler metal that has matching strength, meaning that the minimum specified tensile strength of the filler metal matches that of the base metal. However, this is not always the best option. In some cases it may be beneficial to use undermatching filler metals. There are many factors to consider when selecting the right filler metal. Understanding requirements in the areas of strength, ductility, wear resistance, corrosion resistance, in-service demands, cost and productivity is essential.
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, […]
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 […]
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 […]
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 […]
The ability to write and/or interpret welding symbols is essential for many welding industry professionals including welders, supervisors, CWIs, welding engineers, estimators, QC personnel and more. Yet, less than 5% of the customers we consult with have at least a basic understanding of welding symbols. Welding symbols communicate vital information to the welder. It allows […]
The ability to develop welding procedures for aluminum and aluminum alloys coupled with the ability to weld these alloys is becoming even more important for fabricators. Whether it is a job shop producing different products every day or a firm that specializes in a single product, the ability to fabricate out of aluminum is necessary. […]
The design of pressure vessels is quite interesting. At first it may appear extremely complicated. Then, you learn the basics of pressure vessel design and realize it is not that big of a deal. But, then you get into all variations of vessel heads and shells, the different kinds of loading conditions (it’s not just […]
The following is an exerpt from: TROUBLESHOOTING FOR NON-WELDING ENGINEERS There is nothing wrong with concave welds so long as they attain the desired throat dimension. AWS D1.1/D1.1M:2020 Structural Welding Code (Steel) states that “there is no restriction on concavity as long as minimum weld size (considering both leg and throat) is achieved.” Concave welds […]
