ARC Welding

The open arc welding method uses an electric arc to create a weld in open air, without a gas shield. This process deliberately adds nitrogen from the atmosphere to the weld metal. This addition improves the properties of the weld, resulting in strong and durable joints. The benefits of Open Arc Method Welding include high … Read more

Submerged arc welding (SAW) is a welding process that produces an arc between a continuously fed electrode and the workpiece. A layer of powdered flux creates a protective gas shield and slag, which protect the weld pool. SAW offers high efficiency and accuracy, making it ideal for various industrial applications. The benefits of Submerged Arc … Read more

Nitinol percussive arc welding uses micro arc TIG welding and a mechanical percussive movement to join superelastic nitinol wires. This technique overcomes welding challenges like heat sensitivity. Optimal welding parameters include a power range of 54 W to 72 W. This method is effective for various manufacturing applications and ensures good weld quality. The impact … Read more

A non-arcing aluminum welding lead ensures a stable arc during aluminum welding. Troubleshoot issues by checking for oxidation and proper gas flow. Use high-quality leads with copper guides. Address wire feeding problems and ensure clean surfaces. Proper grounding clamps also improve arc stability and enhance overall welding performance. Additionally, these leads are lighter and more … Read more

Non-arcing welding lead material includes copper wire strands with rubber insulation. This structure stops electrical arcs during welding.

Numerical problems in arc welding require calculations involving voltage, current, and heat transfer efficiency. For example, you might calculate using 25 V voltage and 300 A current on low-carbon steel. These problems help determine welding speed and current requirements based on steel plate thickness, often seen in SMAW scenarios and GATE exams. For instance, a … Read more

The NYSDOT Field Welder Certification Manual for Shielded Metal Arc Welding (SMAW) details the certification process for welders. It covers groove and fillet welds in positions like 3G and 4G. Welders need to meet proficiency requirements and follow electrode specifications based on AWS standards for field welding approval. Welders who achieve certification benefit from job … Read more

The minimum thickness for arc welding is usually 1.5 mm to 2 mm. Choose a welding rod size that is one size smaller than the material thickness. Set the amperage between 20 to 50 amps for each millimeter of thickness. Use the correct welding method and equipment, such as Gas Tungsten Arc Welding or Plasma … Read more
