MIG Spot Welding is a variation of Metal Inert Gas (MIG) welding where the process is used to create spot welds, typically on thin sheet metals. It replaces traditional resistance spot welding by using a short weld cycle and shielding gas to prevent contamination. MIG spot welding is fast, efficient, and suitable for high-volume production environments such as automotive manufacturing. It requires less pressure and offers good aesthetic results on visible joints.
TIG Welding (Tungsten Inert Gas) uses a non-consumable tungsten electrode and an inert gas (usually argon) to produce high-quality, precise welds. It’s ideal for thin materials and critical joints in stainless steel, aluminum, and exotic metals. TIG welding allows better control over heat and weld puddle, making it perfect for detailed or aesthetic work. While TIG is slower than MIG, it provides superior finish and strength, especially important in aerospace, automotive, and pipe welding applications.
Continuous Wire Feed : A spool of wire acts as both the electrode and filler metal.
Shielding Gas Protection : Inert or semi-inert gas (like CO₂ or Argon) shields the weld from contaminants.
High-Speed Welding : Suitable for long, continuous welds on thick or thin materials.
Automatable : Easily adapted for robotic or mechanized welding.
Pressure + Electric Current : Electrodes clamp two metal sheets together and pass high current to create a weld.
No Filler Metal Required : Uses only base materials to form the weld joint.
Fast Cycle Time : Commonly used in high-speed mass production (e.g., automotive bodies).
Works Best with Thin Sheets : Especially low-carbon steel.
