TIG welding offers exceptional precision, producing high-quality welds with excellent aesthetic appeal. It is commonly used for thin materials, critical joints, or projects that require utmost accuracy.
-
Arc Welding: Arc welding, also known as Shielded Metal Arc Welding (SMAW), employs an electric arc between a consumable electrode and the base metal. The electrode’s flux coating creates a protective shield, preventing impurities from contaminating the weld. Arc welding is versatile, making it suitable for various applications, including heavy-duty construction, maintenance, and repair work.
In the following sections, we’ll delve deeper into each welding technique, exploring their advantages, disadvantages, and widespread applications. Join me as we uncover the secrets behind the art of welding with MIG, TIG, and Arc methods.
