MIG Welding Wire

MIG Welding Wire

AIMS Industrial sells MIG welding wire from Bossweld, Safra, Gemini, BT and Inefil — covering mild steel solid wire, stainless steel solid wire, gasless flux-core wire and hardfacing wire in a range of diameters and spool sizes. Whether you’re production welding mild steel or restoring worn components with hardfacing, AIMS has the wire grade for the job.

MIG Wire Types

• Mild Steel ER70S-6 (Gas-Shielded): The most common MIG wire grade. ER70S-6 is a copper-coated solid wire for welding mild and low-alloy steel with CO₂ or Argon/CO₂ mixed gas shielding. Excellent arc stability and weld pool fluidity. Available from Bossweld, Safra, Gemini and Inefil.
• Stainless Steel MIG Wire: ER316LSi grade for welding 316 and 316L stainless steel components. Used in food processing, marine, chemical and architectural applications where corrosion resistance is paramount. Available from Bossweld.
• Gasless Flux-Core Wire: Self-shielded flux-core wire requires no external shielding gas — the flux within the wire core generates its own shielding. Ideal for site work, outdoor welding and portable MIG applications. Available from Bossweld.
• Hardfacing Wire: Specialised alloy wire for depositing a hard, wear-resistant weld overlay on components subject to abrasion, impact or metal-to-metal wear. Used in mining, quarrying, agriculture and plant maintenance. Available from Bossweld.

Key Products

• Bossweld 70S-6 Mild Steel MIG Welding Wire — ER70S-6 copper-coated mild steel MIG wire in various diameters and spool sizes.
• Bossweld 316LSi Stainless Steel MIG Wire — for welding 316 and 316L stainless steel with Argon-based shielding gas.
• Bossweld GLX Hardfacing Gasless MIG Wire — self-shielded hardfacing wire for wear surface overlay applications in mining and heavy industry.
• Bossweld Gasless GS MIG Wire — general-purpose self-shielded flux-core wire for outdoor and site welding without a gas bottle.

Selecting the Right Wire Diameter

• 0.8 mm: Suitable for thin sheet metal (1–3 mm). Common in automotive, HVAC and light fabrication.
• 0.9 mm: General-purpose diameter for structural steel and medium plate (3–8 mm). The most widely used MIG wire diameter.
• 1.2 mm: Heavier plate and structural welding. Higher deposition rates for production environments.

Typical Applications

• Structural steel fabrication and general metalworking
• Automotive body repair and restoration
• Stainless steel fabrication for food, marine and chemical industries
• Maintenance and repair welding on mining and agricultural equipment
• Hardfacing for buckets, blades, wear plates and crusher components
