Dissimilar TIG Fillers are specialist welding consumables designed for joining different grades of steel, stainless steel and other difficult-to-weld materials. This category includes ER309L and ER312 TIG filler rods, providing excellent crack resistance, high strength and reliable weld quality for dissimilar metal joining, buffer layers, repair work and maintenance applications.
Ideal for fabrication, structural engineering, maintenance and repair industries, dissimilar TIG filler rods are commonly used for joining carbon steel to stainless steel, armour plate, tool steels and wear-resistant alloys. Their versatile metallurgical properties help minimise cracking while delivering strong, durable welds in demanding service conditions.
