ARC Welding

Arc welding is effective for many tasks, including steel erection, heavy equipment repair, and pipeline welding. It plays a crucial role in construction projects, manufacturing, automotive work, and metal fabrication. Its versatility and cost-effectiveness make it a valuable technique across various industries. The benefits of arc welding are significant. First, it provides strong welds that … Read more

Arc welding operates by using a power supply to create an electric arc between the electrode and base material. This arc produces intense heat that melts the base metal, the core of the electrode, and the flux coating. The flux coating shields the weld from contamination during the welding process, ensuring a strong bond. Arc … Read more

Arc welding was practically invented by Russian inventor Nikolay Benardos in 1881. He introduced carbon arc welding, a method that significantly advanced welding techniques. Earlier, Egyptians practiced welding on iron around 3000 B.C., showcasing their early craftsmanship in this important field. In 1901, American engineer Elihu Thomson improved arc welding machines by introducing a more … Read more

Leather gloves are best for arc welding because of their durability and heat resistance. For stick welding, use thick gloves like Tillman or Revco Black Stallion 850 for protection. For TIG welding, thin goatskin gloves offer better dexterity. Always select gloves that match your welding technique for safety and comfort. Fit is another crucial factor. … Read more

When arc welding, wear fire-resistant clothing like wool and a heavy coat. Use cotton gloves for hand protection. Protect your eyes with tinted glasses, ensuring the lens shade is at least 10. A welding helmet and safety glasses with side shields are essential for full eye protection. Follow OSHA regulations for safety guidelines. It is … Read more

Arc welding started in 1881 when Nikolai Benardos showcased the method with a carbon electrode at the International Exposition of Electricity in Paris. He patented this technique in 1887, with Stanisław Olszewski, marking a key development in the history of welding technology. The timeline of arc welding’s evolution showcases significant milestones. In the 1920s, the … Read more

Arc welding uses a consumable electrode that melts with electricity and does not need an external gas source. It has a flux coating to protect the weld from atmospheric gases. In contrast, MIG welding also uses a consumable electrode but requires an external gas for shielding. This gas improves the quality of the weld. The … Read more

For arc welding, wear lens shades between 10 to 14 for the best protection level. Use shades 10 to 13 for MIG welding and shades 8 or higher for TIG welding. When gas cutting, a shade 5 lens filters light without blocking visibility. Always check OSHA guidelines for specific amperage requirements. Shade 10 offers protection … Read more

For Shielded Metal Arc Welding (SMAW), choose your lens shade based on amperage. OSHA guidelines recommend a shade #7 lens for welding below 60 amps. Use shade #8 for 60-100 amps, shade #9 for 100-200 amps, shade #10 for 200-300 amps, and shade #11 for 300+ amps. Always prioritize welding safety. For most arc welding … Read more

The ANSI recommends shade numbers for arc welding based on the arc current. For Gas Metal Arc Welding (GMAW) and Flux Cored Arc Welding (FCAW), use shade 11 for 60-160 amps, shade 12 for 160-250 amps, and shade 14 for 250-500 amps. For Gas Tungsten Arc Welding (GTAW), use shade 10 for under 50 amps. … Read more
