The recommended minimum plate thickness for arc welding depends on the stud base diameter. For steel and aluminum: ½ inch (0.120”) needs 13 ga, 5/8 inch (0.148”) needs 11 ga, and 7/8 inch (0.250”) is best for thicker materials. Consult industry standards for precise values. Limitations arise when considering material type and welding method. Certain … Read more

Always disconnect the battery and power down electrical systems before arc welding near electronic equipment. The welder’s current can damage or short-circuit components. Take necessary safety precautions to prevent equipment failure. Ensure a safe working environment to enhance safety during the welding process. To protect electronic equipment, workers should implement several strategies. First, cover all … Read more

Arc welding noise assessment measures acoustic pressure levels, focusing on ultrasound frequencies. It uses A-weighting-filtered sound pressure across 1/3 octave frequency bands. The results identify sound pressure changes before and during welding. This process supports quality control and background noise evaluation. By analyzing ultrasonic waves, we can identify the sources and characteristics of welding noise … Read more

An arc welding non-consumable electrode is mainly made of tungsten. It is used in gas tungsten arc welding (GTAW), often called TIG welding. During this process, an inert gas protects the welding area. A separate filler material may also be used to connect the two metals being welded together. The primary role of the tungsten … Read more

Plasma Arc Welding (PAW) is a modern arc welding method. It uses a tungsten electrode to create a high-temperature electric arc. This arc melts metals and enables coalescence. PAW requires an inert shielding gas for protection. Its precise control makes it ideal for manufacturing and fabrication across various sectors. There are two primary types of … Read more

The prefix “E” identifies an arc welding electrode. The first two digits of a 4-digit number and the first three of a 5-digit number show the electrode’s minimum tensile strength in psi. For instance, E6010 means a tensile strength of 60,000 psi, while E10018 indicates 100,000 psi. Knowing these classifications helps welders select the right … Read more

Arc welding joins aluminium and its alloys, including the 1xxx, 3xxx, 5xxx, 6xxx, and 7xxx series. The 5xxx series has excellent weldability. This process enables fusion welding, creating strong and durable connections for various applications. Arc welding is essential for effective metal joining in numerous industries. TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas) … Read more

Arc welding joins ferrous and non-ferrous metals with an electric arc that forms between a carbon electrode and the metal. It may use filler metal for better results. This welding process offers precision but has slower speeds. Due to inefficiencies, it is less commonly used in modern industrial applications. In contrast, non-ferrous metals, including aluminum … Read more

Martensitic stainless steel contains up to 18% chromium and has good weldability. Use low-hydrogen electrodes for Shielded Metal Arc Welding (SMAW) and preheat the steel to 400-450°C. Post-weld heat treatment may be required. Suitable welding methods include SMAW, Gas Metal Arc Welding (GMAW), and others. Control the heat input during welding. High temperatures can lead … Read more
