What are the four main processes of welding?

The four main processes of welding identified in the correct answer encompass techniques that are widely used in the welding industry, which are crucial for various applications. Shielded Metal Arc Welding (SMAW), also known as stick welding, uses an electrode coated in flux to create a shield of gas and slag around the weld, thus protecting it from contamination. This technique is known for its versatility and is often used in fieldwork and repair jobs.

Gas Metal Arc Welding (GMAW), or MIG welding, employs a continuous solid wire electrode and an inert gas mixture to protect the weld pool. Its fast operation makes it a popular choice in manufacturing and fabrication due to the ability to weld a range of materials and thicknesses efficiently.

Gas Tungsten Arc Welding (GTAW), or TIG welding, uses a non-consumable tungsten electrode and is known for producing high-quality welds on thin materials. Its precision is essential in industries where the aesthetic quality of the weld is critical, as well as in applications involving exotic materials.

Flux-Cored Arc Welding (FCAW) operates similarly to GMAW but uses a tubular wire filled with flux. This method provides good penetration and is particularly effective for welding thicker materials and outdoors where wind might affect shielding gases
