Cracking is a big problem in welding. Many of our customers experience cracking problems on an ongoing basis. Unfortunately, these cracks are not always detected in the shop. Many times cracking occurs once the product is in service. In these cases, cracking can lead to failure and at the very least an upset customer. In […]
Most types of stainless steels have good weldability and can be welded with all arc welding processes (GMAW, FCAW, GTAW, SMAW and SAW). Stainless is used in many different applications for its strength, abrasion resistance and corrosion resistance. Unfortunately, many assume it can be welded just like carbon steel. In fact, this is the first […]
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 […]
Competition amongst manufacturers of welding machines is a wonderful thing. Companies like Miller, Fronius, OTC, Lincoln Electric, and many others are continuously improving their equipment, making it more user-friendly and at a lower cost. We as users benefit from this. However, this has brought about a big problem. And that is the belief that we […]
Prequalified welding procedures must adhere to the strict requiremnts of the welding codes which permit their use. AWS D1.1 Structural Welding Code (Steel) is one that allows their use. Prequalified WPSs are exempt from testing becasue there is reasonable assurance that as long as all the requirements are met the deposited weld will be sound […]
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 […]
Shielded metal arc welding (SMAW), or what is commonly referred to as “stick welding,” is one of the oldest welding processes. Despite being one of the first welding processes developed, it remains one of the most used welding process worldwide. If you have been working in a fabrication shop for years using advanced GMAW (mig) […]
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 […]
