ARC Welding

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

Arc welding noise levels in metalworking vary. For Welding/MMA, levels are 85 to 95 dBA. MIG welding ranges from 95 to 102 dBA. Arc air gouging produces 104 to 125 dBA. These sounds may cause hearing damage, so use hearing protection to follow OSHA regulations. In addition to health risks, excessive noise can affect communication … Read more

फ्लक्स शील्डेड मैटल आर्क वैल्डिंग (FMAW) एक प्रमुख प्रक्रिया है। इसमें वेल्डिंग से पहले जॉब को 205 °C तक प्री-हीट और 730 से 790 °C तक पोस्ट-हीट करना जरूरी है। मुख्य प्रकारों में SMAW और TIG वेल्डिंग शामिल हैं। सही वेल्डिंग उपकरण और तकनीक से उच्च गुणवत्ता प्राप्त होती है। Additionally, the guide explains various … Read more

Arc welding is a process for joining metals. It uses an electric arc to create high temperatures, exceeding 5500°C. A power supply provides energy, and electrodes—either consumable or non-consumable—melt the metals. This method includes various welding techniques, ensuring strong and precise welds for many industries. The SlideShare emphasizes the importance of safety practices, equipment handling, … Read more
