TTU948 - R45 Oxy-Acetylene Mild Steel Welding Rod 2.5mm 1lb

High-Quality R45 Mild Steel Gas Welding Rods

The RG4525-1 is a premium quality, general-purpose mild steel welding rod designed specifically for oxy-fuel gas welding applications. Manufactured to meet AWS A5.2 Class R45 standards, this filler metal is an essential consumable for fabricators, maintenance teams, and metalworkers who rely on the precision and control of oxy-acetylene welding. The rod features a nominal diameter of 2.5mm, making it an excellent middle-ground choice for bridging gaps in medium-gauge sheet metal or performing root passes on pipe welds.

One of the defining characteristics of this R45 rod is its copper coating. This thin layer serves a dual purpose: it significantly extends the shelf life of the product by preventing oxidation and rust on the steel surface, and it ensures smooth handling during the welding process. The core wire is a low-carbon steel formulation that produces welds with high ductility. This property is crucial for applications where the welded joint may need to undergo subsequent machining, bending, or forming without cracking. The weld deposit exhibits a minimum tensile strength of 45,000 psi, providing structural integrity for non-critical applications.

When using this rod for mild steel, no flux is required, which simplifies the welding process and allows the operator to maintain a clear view of the weld puddle. The molten pool is fluid yet controllable, wetting out smoothly to the base metal toes. This makes it particularly effective for welding wrought iron, low-carbon steel pipes, and steel plates. Whether you are repairing vintage automotive parts, fixing steel furniture, or engaging in artistic metal sculpture, the R45 2.5mm rod delivers consistent, porosity-free results.

Packaged in a convenient 1lb tube, this product is ideal for small-to-medium jobs where bulk quantities are unnecessary. The 36-inch cut lengths are standard for the industry, providing enough reach to keep the welder's hand away from the heat zone while minimizing waste. Trust in the reliability of this general-purpose gas rod for all your oxy-fuel welding needs.
