High-Roller Tig Welders - The amelioration through The Years

When it comes to the commerce of welding, Tig welders are possibly the high-rollers. For one, the techniques they employ are some of the most difficult in the field. High level of hand operate and accuracy is necessary. And not to mention, the formula is also far more complicated, especially when compared to the simplistic and more direct arrival of Smaw (stick welding).

And although not as widely used in the commerce compared to Smaw, Tig Welders enjoy a high examine in the industry. This is partly due to the fewer whole of welders that can do the formula and deliver convincing quality. If you want to have higher chances of nailing consistent job offers in this field, it is good to learn Tig as an increasing to your repertoire of skills.

Another speculate why it is the high roller of the field is its allembracing application in aerospace. So if you know how to do Tig welding, you can be proud of yourself knowing that something very similar is used by engineers in construction and developing very involved space vehicles.

Given the complexity and the high skill requirement of the technique, it did not just sprout out of nowhere. It was pretty much a work in progress. Through the years, several techniques kept changing until it achieved its mature form today.

The needed weld non-ferrous metals

The first idea of using inert gases in welding hatched about 90 years since the discovery of electric arc. This took place colse to the year 1890. However, the formula still posed many ability problems when it comes to dealing with non-iron based metals like copper and magnesium.

Later in the year 1930s, the integration of bottled inert gas into the technique improved things exponentially. It improved supplementary when the application of direct current was added into the method. Later, welding metals like magnesium became more productive.

Application of alternating current

The use of inert gases came with the utilization of tungsten rod. It was ideal because tungsten has a very high melting point and can withstand high levels of heat. However, this still did not preclude tungsten particles from getting mixed into the weld, which is undesirable.

To correct this, Tig Welders back then plan of changing the current to negative. It did prevented tungsten particles from collapsing but it made the whole procedure unsuited for non-ferrous metals. Later, the application of alternating current solved the problem for Tig welders.

Use of plasma

The improvement of the technique did not stop with tungsten and alternating current. Later, a more advanced formula made use of plasma. This afforded Tig Welders great close and great ability with the work pieces.

Another increasing to it is the use of a nozzle which provided Tig Welders great control. However, this technique which is often called plasma arc welding is primarily an self-acting method. For hand-operated operations, the acceptable techniques are still employed. Both methods however have their own advantages and disadvantages too and would work well on dissimilar situations.
