ARC Welding

To select a tungsten electrode: Choose Lanthanated (Blue) for DC, Thoriated (Red) for AC, Zirconiated (Brown) for DC or AC/DC, and Ceriated (Orange) for versatile use. Match the electrode type to your welding mode—TIG—and power source type. This ensures the best performance and results. The Arc Welding Electrode Color Chart is a vital tool for … Read more

Arc welding does not include Tungsten Inert Gas (TIG) welding. Arc welding uses an electric arc to generate heat and join metals. In contrast, TIG welding uses a non-consumable tungsten electrode. Knowing these differences helps in understanding various welding types and processes. Common misconceptions about arc welding safety often lead to reckless behavior. Some welders … Read more

To calculate arc welding current, follow the rule of 1 amp per 0.001 inches of material thickness. For example, for a thickness of 0.060 inches, you need 60 amps of weld current. This calculation helps achieve proper weld penetration and ensures effective welding based on established welding process rules. Voltage plays a significant role in … Read more

Arc welding is a welding method that joins metals using an electric arc. This arc creates thermal energy that melts the metal surfaces, allowing them to fuse. In Telugu, it is called “మెటల్ ఆర్క్ వెల్డింగ్.” The process requires an electrode and filler metal for creating strong, reliable joints between metal parts. ఆర్క్ వెల్డింగ్ అనేది మేటి … Read more

Arc welding is a welding method that uses an electric arc to create heat. This heat melts and joins metals together. A power supply starts the arc between a consumable or non-consumable electrode and the metal. It can use direct current (DC) or alternating current (AC) for efficient joining in mechanical engineering. The benefits of … Read more

To select welding current in arc welding, consider plate thickness and electrode size. Use lower amperage for thin plates and higher amperage for thick ones. Choose direct current (DC) or alternating current (AC) based on the electrode type. Adjust voltage carefully to manage arc length and thermal energy for the best weld quality. Voltage settings … Read more

Recommended amperages for stick welding electrodes vary by type and diameter. Use these ranges: – 1/8 inch: 75-150A – 5/32 inch: 110-200A – 3/16 inch: 140-255A – 7/32 inch: 170-320A These ranges ensure optimal weld quality according to the electrode size. This amperage chart lists recommended settings based on the diameter of electrodes and the … Read more

The arc welding data logger is a portable device that monitors and records welding parameters like voltage, current, wire feed speed, travel speed, and gas flow. It logs data for up to 4,000 welds, ensuring comprehensive analysis. With real-time monitoring and user-friendly data export capabilities, it meets industry standards. Key monitoring benefits include increased consistency … Read more

DC positive polarity in arc welding offers deeper penetration in steel and is best for thick materials. In contrast, DC negative polarity has lower penetration but allows for a higher deposition rate. This makes it suitable for welding thin sheet metal. Choose the polarity based on your material thickness and desired weld characteristics. On the … Read more

DC stick welding usually has an open circuit voltage of about 80 volts and a load voltage around 30 volts. This direct current provides a stable arc, which is important for effective welding. To initiate the arc, the voltage is higher than during operation, typically between 20 to 30 volts. In contrast, Alternating Current (AC) … Read more
