What is Low Hydrogen Open Root Welding? Low hydrogen open root welding is a technique that combines the use of low hydrogen electrodes with an open root joint configuration. This approach is crucial in preventing hydrogen embrittlement, a metal failure caused by trapped hydrogen leading to brittleness and fractures. Low hydrogen electrodes are designed to…
When you’re aiming for clean and successful welds, the way you initiate the arc plays an important role. In TIG welding (Gas tungsten arc welding –GTAW), getting off to the right start isn’t just about skill; it’s about choosing the right technique for the job. Today, we will compare tig welding ignition methods: scratch vs lift…
Quick connect fittings used in compressed air systems must comply with specific regulations and standards to ensure both safety and operational efficiency. These rules require that both fittings and hoses are appropriately matched to the air system’s demands, minimizing the risk of leaks and guaranteeing optimal performance. Compliance with these standards protects the system’s integrity…

Not all metals are easy to weld together. Some metals have different physical and chemical properties that make them incompatible for welding. One of the most challenging combinations of metals to weld is steel and aluminum. Steel and aluminum are very different metals with respect to their melting points, thermal conductivities, expansion coefficients, and solubilities….
When it comes to welding, one of the most critical aspects to understand is the different types of joints in welding that are utilized to create strong and durable welded structures. The joint is where two pieces of metal are fused together through the welding process. Selecting and properly preparing the right type of joint…
AC and DC welding are two different types of welding currents that affect how the arc is created and maintained between the electrode and the workpiece. AC stands for alternating current, which changes its direction periodically. DC stands for direct current, which flows in one direction only. The choice of welding current can have a…
