E309L-16

The world's most popular solid MIG/TIG welding wire for carbon steel. High manganese (1.40-1.85%) and silicon (0.80-1.15%) content provides superior deoxidizing power — welds cleanly even on slightly rusty or oily steel. Copper-coated for smooth wire feeding. Produces X-ray quality porosity-free welds with excellent bead appearance. Used with CO2 or Ar/CO2 shielding gas. Minimum 480 MPa tensile strength. Used for general fabrication, structural steel, shipbuilding, pressure vessels, automotive, and construction. The go-to wire for every MIG welder.

The world's most widely used low-hydrogen SMAW (stick) welding electrode. Iron powder + calcium fluoride coating produces smooth, easy-to-control arc with minimal spatter and easy slag removal. Low hydrogen designation prevents hydrogen-induced cracking in structural joints. All-position welding (1 = flat, horizontal, vertical, overhead). AC or DCEP. Minimum 480 MPa tensile strength. Must be stored in heated ovens (250-300°F) to prevent moisture pickup. Used for structural steel, bridges, buildings, pressure vessels, and all code-compliant fabrication per AWS D1.1.

Low-carbon austenitic stainless steel welding wire — the standard filler for joining 304 and 304L stainless steels. The L (low carbon ≤0.03%) prevents sensitization and intergranular corrosion in the heat-affected zone. Used for TIG (GTAW) and MIG (GMAW) with pure argon or Ar/CO2 shielding. Produces fully austenitic-ferritic weld metal with 5-15 FN (Ferrite Number) for crack resistance. Used for food processing equipment, chemical tanks, pharmaceutical vessels, and architectural stainless fabrication.
