Quality and cost go hand in hand, or at least they should. Poor quality may be cheap during the fabricating process, but very costly when it comes to warranty repairs and potentially losing customers. Many of the companies we work with have seen substantial cost reductions when we help them address quality concerns. For the […]
Spatter is present in welding. It’s all over welding. But it doesn’t have to be. Spatter costs fabricators millions of dollars every year. Its removal constitutes rework that significantly and negatively impacts productivity. Many fabricators work under the assumption that spatter is a necessary evil, a part of welding. However, this couldn’t be further from […]
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 […]
One of the first steps in analyzing cracks to find their root cause and take corrective action is to categorize the cracks. We categorize cracks based on three elements. Location Direction Timing In today’s article we discuss the importance of crack location when trying to determine what caused it. What follows is an excerpt from […]
A repair procedure is necessary any time there is a defect in welding that must be corrected. The repair procedure is not just a welding procedure specification, but rather a set of instructions and rules on how to repair different types of defects. There is no standard format for a repair procedure, or a standard […]

Undercut is a surface discontinuity resulting from melting of the base metal at one or both toes of a weld which remains unfilled by the weld metal. It can also occur at the root of groove welds. Undercut presents two problems. First, it forms a mechanical notch which acts as a stress riser and is […]
Troubleshooting of welds and other welding problems increases costs in welding, causes delays and affects weld quality. Even a moderate understanding of welding problems, their symptoms, causes and potential solutions can help tremendously. The more informed you are the better. To successfully troubleshoot and fix welding discontinuities, welding defects and other welding problems we need […]
Maintenance-related problems are responsible for a large portion of bad welds in every day welding. However, these causes go unnoticed and unresolved because they happen slowly over time. A proper preventive maintenance program for welding machines, CNC cutting tables and other industrial equipment is absolutely necessary. Many of the problems related to maintenance that cause […]
Bigger is not always better, at least not in welding. Making welds bigger than they need to be is not only wasteful and costly, but can cause other problems such as distortion and premature failure. Below are 3 reasons why you may need to pay close attention to your weld sizes. 1. Bigger welds cost […]
