Copper is a great all around metal for a variety of construction and manufacturing purposes. Copper corrosion resistance, thermal conductivity and high electrical, easy to make and holds up well under pressure and fatigue. If you want to join copper, welding is a great method. While soldering and brazing are also ways in which you can create copper bonding, welding creates powerful connections and is recommended in most cases.
Type Copper Alloys
There are eight major categories of copper alloy. It is as follows: Pure copper (copper content at least 99.3 per cent), high copper alloys (no more than 5 percent of any material other than pure copper), copper-zinc alloys (brass), copper-tin alloy (phosphor bronze), copper aluminum alloys (aluminum bronze), copper silicon alloys (silicon bronze), copper nickel alloys, nickel and copper-zinc alloys (nickel silver). Copper alloys are rarely require heating before welding. Pure copper, on the other hand, does not require preheating.

Copper Welding Preparation
Before starting welding make sure you wear proper safety attire. A welding mask, also called a welding helmet, should be worn to protect the eyes and face. Welding causes heat, sparks and flashes of light. All of this can be dangerous for your health. You also have to wear welding gloves to protect your hands, and make sure your clothes fit and do not have loose threads that can be burned during the welding process. Make sure that the copper net of any debris, grease, dirt, paint or other foreign material. Wearing a welding apron will provide extra protection. The best way to ensure this is to clean the copper with a wire brush and degreasing agent.
Copper Welding
Arc welding is the most common form used and recommended when it comes to welding of copper and copper alloys. These include gas tungsten arc welding, plasma arc welding, gas metal arc welding, and submerged arc welding. As mentioned above, only pure copper needs to be heated, but high heat should be used no matter what kind of copper or copper alloy welding you. Therefore, you will want to turn up the amperage on your welding machine to weld successfully. Once you have finished welding, cleaning copper with a wire brush.
