Welding wire SPG1A CU rods 3.25mm /10kg/ 1161011327

Copper-coated welding wire – reliability in the workshop and on the construction site

This welding wire, with a diameter of 3.25 mm, is a proven choice for both professional welders and those performing occasional welding work. Designed for oxy-acetylene welding of low and low-alloy steels, it provides solid and durable connections. Supplied in rods of 1000 mm length, it is ready to use immediately after unpacking.

Universal application and compliance with standards

The SPG1A CU wire meets the requirements of PN-EN 12536: O1 and AWS A5.2: R 45 standards, guaranteeing its quality and safety. CE approval confirms compliance with European standards. It is suitable for welding structural steels used in various industries – from construction to the production of machines and equipment. It can be used for butt and fillet welding.

Chemical composition and mechanical properties – the key to strength

The precise chemical composition of the wire (C=0.1%, Si<0.15%, Mn=0.5%) affects its welding properties and the mechanical properties of the weld. Yield strength (330 MPa), tensile strength (450 MPa) and elongation (20%) values ensure the solidity and resistance of connections to loads. Low sulfur content (Si: 0.03%) minimizes the risk of cracks and weld defects. The use of a copper-coated coating provides a stable welding arc and facilitates the welding process.
