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…
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…
Tungsten has been an important part of the welding industry with a specialized welding process named after it–TIG or Tungsten Inert Gas Welding. Since the 1940s, tungsten electrodes have proven to be a reliable component for welding a wide variety of metals including–aluminum, carbon steel, titanium, and many more. Tungsten…
Fillet welding a pipe can add complexity to the joint, but comes with its own demands. The most obvious one is the challenge to achieve complete fusion while maintaining the perpendicular angle. To ensure that the fillet welds around a pipe will result in a high-quality and strong joint, we…
Multiple processes use an electric arc to generate heat and create a fusion between two metals– GMAW (gas metal arc welding) and GTAW (gas tungsten arc welding) are the two most prominent. Industries can create an arc manually or mechanically. Mechanical processes, such as orbital welding, are preferred when quality…
December 13, 2022, marks a significant breakthrough for nuclear fusion – a topic of immense interest for decades. Nuclear scientists and enthusiasts worldwide rejoiced at the success of the nuclear fusion experiment that achieved ‘ignition’ – more output energy was yielded than what was consumed to initiate the reaction. The…
Can you weld aluminum with direct current? Although alternating current is the preferred way and direct current has its own limitations when working with sensitive metals, it is possible to use direct current in welding aluminum. But before you make the selection between AC or DC, the critical part is…
