Copper Welding Rods specifications

This article covers the specifications and properties of copper welding rods, as well as their applications and advantages. Understanding these key aspects can help ensure the selection of right copper welding rods and their applications for intended purpose.

Copper Welding Rods are used to join copper, brass, and bronze metals together. Copper welding rods are a popular choice among welders due to their exceptional electrical conductivity, corrosion resistance and high thermal conductivity.

Copper Welding Rods specifications

The most common specifications for copper welding rods include AWS A5.7, EN 24373, and BS2901.

  • AWS A5.6 is the American Welding Society specification for copper and copper-alloy electrodes for shielded metal arc welding (SMAW).
  • AWS A5.7 is the American Welding Society specification for copper and copper-alloy electrodes for Gas welding, TIG Welding & MIG welding.
  • EN 24373 is the European standard specification for solid wires and rods for fusion welding of copper and its alloys.
  • BS2901-3 is a British standard specification for copper welding filler wire rods for TIG and MIG Welding.

Best Copper Welding Rods

When it comes to welding, the quality of the rods you use will determine how strong and durable your welds are. These rods are perfect for joining copper and copper alloys, as well as brass and bronze.
