What Are the Most Common Welding Methods for Joining Two Pieces of Metal?

The most common welding methods for joining two pieces of metal together include the following:

• MIG Welding (Metal Inert Gas): This method uses a continuously fed wire electrode and an inert gas to shield the weld from contamination. MIG welding is known for its speed and versatility, making it ideal for thin materials and projects requiring a strong, clean finish.
• TIG Welding (Tungsten Inert Gas): TIG welding employs a non-consumable tungsten electrode to produce the weld and requires a separate filler material if needed. This method offers precision and control, making it suitable for thin metals and complex welds, although it may be slower than other techniques.
• Stick Welding (Shielded Metal Arc Welding – SMAW): In stick welding, a consumable electrode coated in flux is used to create the weld. This method is particularly effective for outdoor projects and in windy conditions, as the flux coating provides a protective barrier against contamination.
• Flux-Cored Arc Welding (FCAW): Similar to MIG welding, FCAW uses a tubular wire filled with flux, which generates shielding gases when heated. This method is often employed in construction and heavy equipment repairs due to its ability to weld thicker materials and its portability.
• Submerged Arc Welding (SAW): This technique involves the formation of an arc between the workpiece and a continuously fed electrode, with the weld pool submerged under a blanket of granular flux. SAW is highly efficient for thick materials and large production runs but is typically used in industrial settings due to the need for specialized equipment.
