ARC Welding

Cooled tungsten refers to tungsten electrodes, like 2% lanthanated tungsten, used in blue arc welding. They are essential in gas tungsten arc welding (GTAW). The post flow of argon gas cools the tungsten and minimizes oxidation. A post flow time of at least 5 seconds is important for effective cooling during the welding process. To … Read more

The ANSI Z87.1 standard outlines the requirements for eye and face protection, like welding helmets and goggles. It ensures safety against hazards such as impacts and optical radiation. Following this standard guarantees reliable eye protection, essential for welders to work safely in their environments. Arc welding produces ultraviolet (UV) and infrared (IR) radiation. This radiation … Read more

Arc blow is the deflection of a welding arc away from the weld point. This deflection can occur forward or backward from the welding direction. It is a critical issue because it affects weld quality and can lead to defects. Recognizing and mitigating arc blow can improve welding performance and results. The effects of arc … Read more

Arc blow is the deflection of a welding arc away from the weld point in metal arc welding. This can happen in a forward or backward direction. Arc blow affects weld quality. Its causes include magnetic fields and the shape of the workpiece. Understanding these key aspects helps improve welding performance. The causes of arc … Read more

Arc welding is a metal joining process. It uses an electric arc to generate heat. This heat melts the metals at the joint, fusing them together. Two main types are Shielded Metal Arc Welding (SMAW) and Flux-Cored Arc Welding (FCAW). These methods are versatile and commonly used in constructing steel structures. The benefits of arc … Read more

Arc energy in welding is the heat created in the electric arc per unit length of the weld. It is measured in kilojoules per millimeter (kJ/mm). Arc energy shows how efficiently energy transfers from the arc to the workpiece. This impacts weld quality and reduces distortion in the heat-affected zone, ensuring better results. Arc energy … Read more

Arc force is a feature of the Amico welding machine. It boosts the amperage at lower voltage. This results in deeper penetration, making it perfect for tasks like the root pass. Users can adjust the arc force to create a smoother puddle or to enhance digging, based on specific welding needs. When welding in challenging … Read more

Air carbon arc gouging is a thermal cutting process. It uses intense heat from a carbon arc to remove metal from a workpiece. This process requires a carbon/graphite electrode, a power source, and compressed air. The heat melts the metal, allowing for effective shaping or severing. Understanding arc gouging welding techniques is essential for success. … Read more

Arc hunting in welding happens when the welding machine struggles to keep a stable electric arc. This issue often arises from problems with the contact tip or conduit liner. It can result in weak welds. To prevent arc hunting, maintain proper wire feed speed and ensure correct tungsten preparation. The benefits of controlling arc hunting … Read more
