Heat is a complicated subject in welding. If the heat is too low, you will face problems achieving the required penetration. On the other hand, with high heat, you will have issues like cracking, spattering, and undercutting. Undercut in welding (or welding undercut) is a commonly observed defect—especially when welding…
Steel tubing is used everywhere—from refineries to aerospace to pharmaceuticals. It safely and reliably transports process fluids from one point to another. When welding steel tubing, welders have to make sure that the mechanical properties of the metal are not compromised so it can fulfill the reason for use in…
Heat exchangers are exactly what they are called: devices that transfer heat from one medium to another and heat exchangers find wide use in power generation and other industries. Tubesheets are simply sheets of metal perforated with holes that metal tubes can pass through at either end of a heat…
The history of pipe and tube production dates back to the 1900s when a process like hot-rolling was used for large-scale manufacturing. Since then, technologies like welding and seamless manufacturing have allowed the production of a much larger scale of pipes and tubes. Welding accounts for over half of all…
Thin or thick sections, steel or aluminum, TIG welding can join it all. And the fusion ability is not just limited to the material with closely-related properties, but it also extends to dissimilar metals. Creating a reliable bond when the properties of two materials differ drastically is challenging, but much…
Welding in confined spaces is likely to be a familiar, if unpleasant, task for most welders. It can sometimes seem like most welding work needs to be done in an unairconditioned, unventilated broom closet and done to an object that can only be reached through a foot-by-foot hole in the…
The most popular arc welding processes are GMAW and GTAW. The GMAW process is faster; however, GTAW or TIG welding produces higher quality welds. For many industries; such as aerospace, the bar for quality welding requires the process be optimized. Meeting this demand begins with choosing the best materials. Therefore,…
