TTU947 - RG45 Mild Steel Oxy-Fuel Welding Rod 1.6mm (1/16") - 1lb Tube

High-Quality RG45 Mild Steel Gas Welding Rod

The RG45 Gas Welding Rod is a premium general-purpose filler metal designed specifically for oxy-fuel welding applications. With a diameter of 1.6mm (approximately 1/16 inch) and a standard length of 36 inches, this rod is engineered to provide superior control and weld quality on low-carbon steels. Manufactured to meet AWS A5.2 Class R45 specifications, it delivers a minimum tensile strength of 45,000 psi, ensuring structural integrity for general fabrication and repair tasks.

This copper-coated mild steel rod is formulated to flow smoothly under a neutral oxy-acetylene flame, creating a clean, porosity-free weld puddle. The copper coating not only extends shelf life by preventing oxidation but also aids in electrical conductivity if used in alternative applications, though its primary design is for gas welding. It is an excellent choice for welding wrought iron, steel plate, and pipe where the slow heating and cooling cycle of gas welding is beneficial.

Technical Performance and Application

One of the key benefits of the RG45 rod is its ability to produce ductile, machinable welds. Unlike higher-strength rods that may create brittle heat-affected zones in certain conditions, the R45 grade maintains a balance of strength and flexibility. This makes it particularly suitable for applications where post-weld machining or forming is required. No flux is needed when welding on clean mild steel, simplifying the process and reducing cleanup time.

Packaged in a convenient 1lb tube, this product is ideal for maintenance, repair, and operations (MRO) environments, as well as educational settings and small fabrication shops. Whether repairing vintage automotive bodywork, fixing steel furniture, or joining thin-wall tubing, the RG45 rod provides the consistency and ease of use required for high-quality manual gas welding.
