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,…
In all industries with high-purity requirements, you will observe one thing in common — stainless steel pipes and tubings. The smooth finish and corrosion-resistant features have been ideal for avoiding contamination due to rusting, bacterial growth, or chemical mix-up. The metal is also heat and impact resistant, providing the required…
Automation has been the driving force behind the modern-day industrial revolution, and its continuous evolution has shaped a new future for productivity and quality. The welding industry has been no exception– modern welding equipment and machines are indispensable tools for welders today. By eliminating most issues of manual technique, welding…
How do you determine the quality and integrity of the weld? Is it based on the size and appearance of the weld or the number of defects? These are critical questions the welders should ask when performing a weld. And the first approach to getting them answered is through visual…
Whenever there is a heat input on the metal, there is an inevitable expansion and contraction. The extent to which this happens is dependent on the intensity of heat, but this basic thermodynamic concept is sure to change the metallic properties during the heating and cooling cycle. In pipes, distortion…
What happens when two workpieces are not leveled well when welding? This is one of the biggest headaches for welders when working with plates, pipes, or tubes. Due to the irregular fit-up, the resulting weld joint from such misaligned workpieces is mostly of low quality with weak strength. In oil…
Purity and quality are two crucial indicators of success in orbital welding, and they are highly dependent on each other. Impurities that rise from improper preparation and control techniques are responsible for creating defects when welding metallic workpieces. Purging is one of the most effective contamination control processes. The need…
