RG45116 - R45 Copper Coated Mild Steel Gas Welding Rod 1/16" (10lb Tube)

Premium R45 Mild Steel Gas Welding Rods

The R45 Copper Coated Gas Welding Rod is a high-quality filler metal designed specifically for the oxy-fuel welding of low carbon steels. Conforming to AWS A5.2 R45 specifications, this general-purpose rod is engineered to produce sound, porosity-free welds with a minimum tensile strength of 45,000 psi. The 1.6mm (1/16 inch) diameter is particularly well-suited for welding thin-gauge sheet metal, small diameter pipe, and wrought iron, offering the operator precise control over the heat input and weld puddle.

Manufactured with a uniform copper coating, these rods are protected against oxidation and corrosion during storage, ensuring that the filler metal remains clean and ready for use. This coating also facilitates smoother feeding and flow characteristics during the welding process. The low carbon chemistry of the R45 grade ensures that the resulting weld deposit is highly ductile and possesses excellent machinability, making it an ideal choice for applications where post-weld grinding or machining is required. Unlike brazing alloys, this rod is designed for fusion welding where the base metal is melted; however, it requires no flux when applied to clean, rust-free steel, simplifying the workflow for operators.

Packaged in a durable 10lb tube, this product is optimized for maintenance, repair, and operations (MRO) environments as well as automotive restoration shops. It performs exceptionally well in all welding positions, provided the oxy-acetylene flame is neutral. Whether used for repairing steel plates, joining pipe sections, or fabricating ornamental ironwork, the R45 rod delivers consistent mechanical properties and a visually appealing bead profile. It is the industry standard for non-critical structural repairs where ease of use and reliable fusion are paramount.
