Before getting into today’s topic we wanted to make you aware of a new resource we are creating and which will be available soon. Prequalified Welding Procedures for Steel Fabricators will provide a list of prequalified procedures written in conformance with AWS D1.1 Structural Welding Code which can be used in the fabrication of carbon […]
Increasing welding and welder efficiency begins by providing the welder the right environment and tools to fully take advantage of their skill. Here are 8 ways to increase welder efficiency.
Rework is extremely costly, especially in welding. If you consider what happens when a weld is rejected it is essentially triples the amount of work. You weld, you remove the weld, you reweld. On top of this it may require additional inspection. So, reducing rework can save considerable amounts of time and money.
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 […]

It is not a secret that increasing our deposition rates, measured in pounds per hour (kg per hour in metric units), can result in increased productivity. Deposition rate is the rate at which we are depositing weld metal. It is different from the melt-off rate. Melt-off rate is the rate at which we consume our […]
Have you ever wondered if there is one type of welding discontinuity or defect that is the absolute worst one to have? Have you heard that cracks are by the far the worst? Or do you think others like lack of fusion, undercut or overlap can be worse? The reality is that there isn’t a […]
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 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.
