Shielded Metal Arc Welding (SMAW) is a welding process that uses an electric arc to join metals. It ensures a stable amperage supply with constant current welding. Preparation involves selecting the right electrode. Safety protocols include wearing protective gear and following safety tips to prevent injuries during the welding process. Safety is paramount in SMAW. … Read more

MIG welding uses a consumable wire electrode fed automatically into the weld joint, with an external gas source creating a shield for clean welds. In contrast, arc welding uses a stick electrode and relies on flux coating for protection without extra gas. Both welding techniques have unique applications and benefits. The key differences lie in … Read more

The minimum protective shade lens allowed in carbon-arc welding is 14. This shade level protects against intense light and harmful rays generated during the welding process. Always use the correct shade lens to ensure safety and follow safety guidelines and welding standards for various welding applications. Selecting the right shade is essential, as the intensity … Read more

A welding arc is extinguished by lifting the electrode too high above the workpiece, changing the work angle, or reducing the direct current. Each of these actions disrupts the stability of the welding arc and decreases its energy, causing it to extinguish. Shielding gas creates a protective atmosphere around the weld area. Common gases include … Read more
