We frequently receive requests for help developing welding procedures for welding on quenched and/or quenched and tempered steels. Sometimes the call for help is to determine why these steels cracked after welding and how to prevent it from happening in the future. Understanding the supplied condition of the steel you are going to be welding […]
Steel is an alloy of iron and carbon along with several other elements in small quantities, all of which have an impact on its properties. Steels can contain varying amounts of carbon and are typically categorized as low, medium or high carbon steels. Low carbon steels are those containing 0.30% carbon or less. Medium carbon […]
Have you heard of post weld heat treatment (PWHT)? Of course you have. If you are involved in welding you have definitely heard this term. But what is PHWT? When is PWHT required? What temperature should PWHT be done at? Heat treating of materials can be a very complicated subject, but when it comes to […]
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 […]

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 […]
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 […]
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 […]
