Plasma Arc Welding or PAW is an arc gas welding process similar to Gas Tungsten Arc Welding (GTAW). More candidly, PAW is a gas-shielded process using a constricted arc between the metal piece and the non-consumable tungsten electrode. The difference between GTAW and PAW is in the way of setting electrodes in the nose of …
DCEN and DCEP in welding are two important current polarities. Both play a crucial role in all types of welding activities. The polarity means the direction of the current that flows through a circuit. In the DCEN circuit, the current moves from the electrode to the workpiece. And in the DCEP circuit, the flow of …
Welding Positions are basically the different angles of joining metals. Normally, there are four types of welding positions namely horizontal, flat, vertical, and overhead. And the most common types of welds are groove and fillet welds. Welders can perform these two welds in all four positions. Besides this, there are special letters to designate fillet …
Welding is a fabrication process of joining materials like metals or thermoplastics by a fusion technique. In the welding industry, there are many types of welding machines depending on the type of welding process. Some of the popular welding machine manufactures are Lincoln, Miller, and Hobart, etc. They produce welding machines of all sizes and …
Welding is one of the strongest things human beings ever discovered since their existence. The application of welding is limitless in various forms on earth, in space, and in water. Welding can join different metals together with different angles. Normally, the welding industry employs five types of welding joints in day-to-day activities. Post Highlights: What …
