Tungsten Silver Alloy Welding Tips

The art of welding requires some key insights into the nature of energy and chemistry. For example, if you are trying to weld together two metals, you need to know at what temperature the metals may melt and merge together at. A common example of such a situation is welding together tungsten and silver to form an alloy.

Nature of Tungsten
Tungsten is a highly reactive element. It is used to help in the welding process by heating an electrode made of tungsten. The electrode is heated to temperatures up to 35,000 degrees Fahrenheit. It is noted that at such high temperatures tungsten tends to be slightly radioactive. It is recommended that the welder wears a respirator so he does not breath in radioactive gases.

Welding Process
Clean off and sand the tip of the tungsten electrode. This removes all moisture from the element and will help it rise to immense temperatures. The welding process that tungsten is used for is categorically called brazing. This is because the tungsten melts off and merges with the new element, in this case silver.

More alloys
Having a pure silver and tungsten alloy is possible, but welders might find it hard to process this alloy without more elements in the batch. It is suggested that elements such as manganese, cadmium or tin are added. Even though there is an elemental benefit to having more products in your alloy, each element has its drawbacks. Tin could create a relatively weaker alloy compared to cadmium, but cadmium is a hazardous element. Manganese is generally thought to be the best element to utilize in the brazing process, but it can often create a "gummy" metal before it hardens and cools.

Design and Support
If the alloy is being created for a design, such as a part for a device or an art project, it is recommended you support the metal through the welding process. The extreme heat may make it difficult for the metals to retain the desired design and shape you want. Therefore, welders should, in some way, have the silver anchored down or supported on the welding table. A work clamp connected to the table can act as a support for the metal. The clamp holds down the metal as you weld.
