Arc welding is a process that uses an electric arc to produce heat. The heat melts metal pieces and joins them together. The heat source comes from the metal electrode and the work surface. It’s important to follow the National Electric Code for safety. Common techniques include Manual Metal Arc Welding and Gas Metal Arc … Read more

Plasma arc welding (PAW) is a precise welding process. It creates an electric arc between a tungsten electrode and the workpiece. The process uses plasma gas to generate high temperatures, melting the metal. PAW produces a clear keyhole and a stable weld pool. It is ideal for thin materials and various applications. There are two … Read more

A deviating arc path in welding happens when the electric arc moves away from the shortest path between the electrode and the workpiece. This can lead to weld seam defects and impact the mechanical properties of the joint. Using proper techniques in MIG arc welding and robotic cells, like the IRB2400L arm, helps minimize deviations … Read more

Electric arc welding is a method that uses an electric arc to create high temperatures. These temperatures melt metals and fuse them together. This technique is widely used in industries for its versatility and reliability. It forms strong bonds between different metal parts, making it effective for a variety of applications. The process begins with … Read more

DC arc welding is a process that uses direct current (DC), flowing in one direction. This method generates stable arcs by maintaining a steady magnetic field. Its advantages include improved penetration and control during welding. It is commonly used in metal fabrication and repair work. In contrast, AC welding utilizes alternating current, which can create … Read more

Submerged arc welding (SAW) is a welding process that creates an electric arc between a consumable wire electrode and a workpiece. The arc is covered by powdered flux, which shields the weld from impurities. SAW is effective for welding thick steel plates and large structures, producing strong and durable joints. This method has a long … Read more

Arc welding is a fusion welding process that uses an electric arc to join metals. The arc produces intense heat that melts the base metal, creating a strong bond. A power source generates the arc between a consumable or non-consumable electrode and the metal, ensuring an effective metal joining technique. Key techniques in arc welding … Read more

Carbon arc welding (CAW) is an arc welding process that joins metals. It generates heat from an electric arc between a non-consumable carbon electrode and the workpiece. CAW effectively welds materials, such as copper, using low voltage and high current. This technique produces efficient and strong coalescence of metals. Beginners should recognize the importance of … Read more

Plasma arc welding (PAW) is a precise arc welding process. It uses a non-consumable tungsten electrode to produce an electric plasma arc. This arc melts metals, like gas tungsten arc welding (GTAW). PAW stands out by using separate plasma and shielding gases, which improves control and creates high-quality welds on ferrous and non-ferrous metals. The … Read more
