Not every welding process is suitable for every job. Selecting the right process depends on the material, thickness, productivity, weld quality, and application.
Know the 6 Major Welding Processes:
√ SMAW (Shielded Metal Arc Welding)
♦ Portable and economical
♦ Best for maintenance, construction, and field welding
√ GMAW / MIG (Gas Metal Arc Welding)
♦ Fast deposition rate
♦ Ideal for fabrication, automotive, and production work
√ GTAW / TIG (Gas Tungsten Arc Welding)
♦ Highest weld quality and precision
♦ Preferred for stainless steel, aluminum, and critical applications
√ SAW (Submerged Arc Welding)
♦ Deep penetration and high productivity
♦ Used in pressure vessels, pipelines, shipbuilding, and heavy fabrication
√ FCAW (Flux Cored Arc Welding)
♦ Excellent for thick materials and outdoor welding
♦ Common in structural steel and offshore fabrication
√ PAW (Plasma Arc Welding)
♦ Narrow, high-energy arc with excellent precision
♦ Used in aerospace, nuclear, medical, and high-precision manufacturing
√ Before selecting a welding process, consider:
• Base material
• Material thickness
• Welding position
• Required weld quality
• Production speed
• Cost and equipment availability
Which welding process do you use the most in your workshop—SMAW, MIG, TIG, FCAW, SAW, or PAW?
