Copper Nickel Welding Electrodes

Why Copper Nickel Welding Electrodes is coated with flux?

Copper Nickel welding electrodes are coated to protect them from reacting with the atmosphere. This is critical as the welding takes place at high temperatures that can cause it to react with oxygen and air. The coating allows the welder to control the voltage of the current. This helps them to strike and maintain a stable arc. It invariably leads to a decrease in work thickness that prevents overheating and ensures optimal weld quality. Apart from this, the coating is done to suit different welding processes.

What factors should be considered when selecting an 90/10 Copper Nickel Welding Rod ?

The 90/10 copper nickel welding rod is a versatile consumable used in welding different materials. Ideally, the welding rod is the same as the material that is welded. The thickness of the rod will be directly inclined to the thickness of the base metal. So select a rod having a thickness that can handle such pressures. The rods can be provided with additional strength by adding certain chemicals to enhance their strength.

Which ErCUNI Filler Wire is used in arc welding?

The ErCUNI NA67 is generally used for gas metal or gas tungsten arc welding methods. This filler wire can also be used as oxy-fuel in welding of 70/30, 80/20, and 90/10 copper nickel alloys. Here a layer of nickel alloy 610 is necessary prior to overlaying the steel using the GMAW weld process.

Which type of DIN 2.0838 Tig/ Mig Rod produces short arc length?

A heavy coated electrode is primarily designed to produce a short arc length in the system.
