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…
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…
When welding a joint from one end to the other, welders use two common ways— butt weld and fillet weld. Butt weld is when the edges of two workpieces are joined end-to-end. But when the weld is made at an angle, the fillet weld is the technique to go for….
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…
