Non-consumable electrodes are welding tools that don’t melt during the process. They are mainly used in Gas Tungsten Arc Welding (TIG welding). Made from tungsten, these electrodes create an electric arc and do not become part of the weld. This ensures accuracy and high-quality results in various welding applications. The main difference lies in their … Read more

Plasma arc welding has key advantages, such as fast metal cutting, automation capabilities, better control over weld quality, and stable arcs. On the downside, it comes with high equipment costs, requires skilled training for operators, and produces noticeable noise during operation. However, plasma arc welding has its disadvantages. The process requires skilled operators, as it … Read more

Manual electrode holders are specifically designed for arc welding and cutting. They are effective if they can safely handle the maximum rated current of the electrodes. Meeting these criteria ensures safe and efficient operation during welding and cutting tasks. Employers should ensure that all welding equipment meets OSHA guidelines. This includes regular inspections, proper training … Read more

MMA welding, or manual metal arc welding, is a type of arc welding. It uses a stick electrode that creates heat through arc ignition when it touches the workpiece. This process needs frequent electrode replacement. MMA welding is popular for its versatility and portability, making it suitable for various applications. In contrast, Arc Welding encompasses … Read more

Arc welding has benefits like low costs and easy portability. It needs less equipment and is user-friendly. However, it is less efficient, creating more waste and consuming more electrodes. Drawbacks include risks of cracking, poor fusion, and residual stresses in welds, which can affect durability and safety. However, SMAW has its drawbacks. The process generates … Read more

To use a proper arc welding technique, hold the electrode holder at a 90-degree angle to the metal surface. Quickly strike the electrode against the metal, then pull it back about 1/8 inch to establish an arc. Maintain this position for precision, ensuring safety and effectiveness throughout the welding process. Additionally, selecting the right amperage … Read more

The principle of electric arc welding involves creating an electric arc between an electrode and a workpiece. This arc generates a high-temperature flame that melts the metal at the welding joint. When cooled, the molten metal fuses and solidifies, forming a strong bond that effectively joins two materials together. There are several types of electric … Read more

To prevent and control distortion in arc welding, use effective techniques: avoid overwelding, utilize intermittent welding, limit the number of weld passes, position welds close to the neutral axis, balance welds around this axis, apply backstep welding, manage shrinkage forces, and plan a careful welding sequence. Another effective method involves controlling the welding speed. A … Read more
