Welding Methods: A Complete Guide to 5 Common Types Overview of widely used welding processes
MIG Welding MIG Welding (Metal Inert Gas Welding) • Also known as GMAW • Uses a continuously fed wire electrode & shielding gas • Applications: Automotive, light fabrication, sheet metals • Benefits: Easy to learn, clean welds, minimal spatter
SMAW (Stick Welding) SMAW Welding (Shielded Metal Arc Welding) • Uses flux-coated stick electrodes • No external shielding gas required • Applications: Construction, shipbuilding, repairs • Benefits: Inexpensive, portable, robust for outdoor conditions
TIG Welding TIG Welding (Tungsten Inert Gas Welding) • Uses a non-consumable tungsten electrode • Filler material may be added manually • Applications: Aerospace, automotive parts, ornamental welding • Benefits: High quality, no spatter, precise control
Plasma Arc & Laser Beam Plasma Arc Welding (PAW) • Uses ionized gas for a concentrated arc • Benefits: Deep penetration, precise heat control • Applications: Aerospace parts, high-strength metals Laser Beam Welding (LBW) • Uses focused laser for joining metals • Benefits: High speed, minimal heat effect • Applications: Automotive, medical devices, precision industries
Summary / Key Takeaways Key Points: • 5 core welding methods: MIG, SMAW, TIG, PAW, LBW • Each method has unique strengths for different materials & applications • Right choice improves efficiency, quality, and durability
