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

Arc length in MIG welding is the distance between the welding electrode tip and the workpiece surface. This distance is dynamic and changes as the welder manipulates the welding torch or electrode holder. Maintaining the proper arc length is essential for ensuring weld quality and arc stability during the welding process. To control arc length … Read more

Arc shielding in welding uses a protective gas or flux in the welding process. In manual metal arc welding (SMAW), a consumable electrode coated with flux creates an electric arc. This arc generates heat and melts the electrode and base metal. The shielding protects the weld pool from contamination, ensuring a strong metal joining. SMAW … Read more

Weaving in metal arc welding is the side-to-side motion of the electrode wire. This motion improves the fusion of the weld metal. To achieve the best results, this movement should be uniform and can progress both horizontally and vertically. Effective weaving enhances weld quality and ensures a smooth, consistent appearance. The primary advantages of weaving … Read more

Arc welding generates intense bright visible light. This light stresses the iris, which cannot react fast enough to shield the retina. This exposure can result in temporary blindness and eye fatigue. To avoid harm, always use safety goggles made specifically for welding. Protective measures are essential for eye safety during the welding process. In addition … Read more

A welding arc is brighter than the sun because it releases intense light near your eyes. This brightness can lead to serious eye damage. Always use a welding mask with a dark shade and UV protection to shield your vision. Safety precautions are essential when working with welding equipment to prevent vision harm. Safety is … Read more

A welding arc is an electrical current that generates heat to join two metals. It forms between the welding electrode and the base material. This heat melts both materials, creating a strong bond. For example, in MIG welding, a wire feeds into the arc, adding filler metal to enhance the connection and improve the weld … Read more

Arc welding gives off ultraviolet (UV) light because it reaches welding temperatures above 3,000 degrees Celsius. This high heat causes strong UV light emission, which is hazardous. Oxyacetylene and oxyhydrogen flames also generate dangerous UV light. Therefore, safety precautions are essential to protect against UV exposure during welding. The hazards of UV light exposure are … Read more

Oxygen does not work for arc welding because it causes oxidation, weakening the weld. Arc welding needs shielding gas to protect the weld pool from atmospheric gases. Processes like GMAW (MIG welding) and GTAW (TIG welding) use inert gases to ensure strong and clean welds. Furthermore, oxygen can produce excessive heat, which may distort the … Read more

Arc welding uses electricity to complete a circuit. You don’t get electrocuted because your body conducts electricity poorly compared to metal. The voltage is usually low enough to avoid harm. However, welders must follow safety precautions, as there are risks of electrical shock, burns, and UV radiation from the arc. The equipment typically uses a … Read more
