ARC Welding

Arc welding splices in an electrode cable are allowed if the cable is repair-free for at least 10 feet from the electrode holder. Cables must have standard insulated connectors. Splices with insulation quality equal to the cable’s are also acceptable. This ensures safety standards and proper functionality during use. First, use high-quality materials to prevent … Read more

The safe distance for welding is 35 feet (10 meters) from the welding area. If movable fire hazards are present, OSHA recommends moving them away from the site. Adhering to these fire safety and welding safety guidelines is essential for maintaining a safe working environment during welding activities. Welders should adhere to specific guidelines for … Read more

To perform a 90-degree weld, hold the welding gun at a 90-degree angle for butt joints and 45 degrees for other types. Use figure eight welding patterns for corner joints. Apply weave patterns for even heat. Maintain the correct electrode position and arc length. Follow safety tips for the best results. Next, implement an appropriate … Read more

A welding arc is an electric discharge between the electrode (cathode) and the base metal (anode). It generates high-temperature plasma and thermal energy through current flow. Factors like cathode temperature and ionized gas impact electron emission, which is crucial for arc stability and effective welding in various processes. Understanding the principles behind the welding arc … Read more

The Arc Pig is an inline device that uses a Tesla coil to boost weld voltage. It helps start an arc without touching the electrode. It runs on welding current and functions as a high-frequency (HF) start device. It can work with AC rigs but only provides HF for arc ignition, not for continuous welding. … Read more

Arc pressure welding is a process that uses an electromagnetic field to boost the arc atmosphere. This creates pressure in the plasma flow. This pressure affects the total arc pressure and welding current density. These factors are crucial for weld quality and stability. The benefits of arc pressure welding are significant. First, it offers high-quality … Read more
