We must have heard about stuffs working with plasma but, what is this plasma exactly? Plasma is the 4th state of matter. It is produced by passing inert gas around an electrical discharge. The gas is blown out at high speeds through the electrical arc and this gas is superheated to the plasma state.

When you are setting up a welding setup, you should make sure that you have safety equipment also ready. The most major accidents happen in welding because of the lack of safety equipment.  The process of welding is relatively simple but the risks that are associated with welding in terms of safety is high. There are always molten metal pieces flying around that could cause injuries.

It is a very well known fact that MIG welding aluminum is a much difficult process than MIG welding steel. Even a minute difference, be it just a negligible variation in the flow of argon or may be just a tweak in the wire could cause a huge mess up during this process. Hence there are certain things that have to be kept in mind while MIG welding aluminum.

There are many protective gears to safeguard the welders while they are at work but it happens that a lot of us don't care much about using the protective gears properly or sometimes get exposed to the harmful Fumes and gases let out during the process. Here are a few points to know about these fumes and gases…

Just like any other works, welding also has its own probability where accidents happen. Most often accidents happen because of the improper precautionary steps taken by the welders or when it happened due to the instrument fault.

1. The evolution of the welding industry started in the early stages, as early that it is mentioned in the Bible; Tubal Cain “forged all types of tools from bronze and iron." This is the first welding ever done in the history.

2. Benardos explained the process of carbon electrode welding in the year 1881 when an extra rod was added to the needed metal.

3. The oxyacetylene welding process was soon developed after the accidental discovery of acetylene in the year 1892 by Morehead and Wilson.

The welding gun is single most important component when it comes to welding. Without which welding becomes absolutely impossible irrespective of what kind of welding technique you pursue. Hence much care should be directed towards the welding gun when it comes to maintenance. The wire feeds through to reach the contact tip or nozzle which allows the welding arc to weld the pieces together.

It is important to have the best of quality equipments and immense knowledge in welding along with at most concentration when we are working with welding applications. Selecting proper engine driven welding generators, plasma cutters and other repair tools helps you to prevent downtime by fixing repair works right at the first time.

Out of all welding methods, Stick Welding or the shield Metal Arc Welding is the most adaptable one which is also versatile. A beginner can also easily handle a stick welder if practiced properly within a short period of time. Just like any other welding techniques, the shield metal Arc Welding also has its own troubles. Here is a list of the most common ones and they are actually easy to handle and identify.

Spot welding, or the practice of creating small, evenly spaced welds on the surface of a combined prior to creating the main weld. Helps to hold jointly two sheets of metal when they are welded. By holding jointly metal pieces, spot welding has the added advantage of reducing any warping or burn-through that may or else have occurred throughout welding. Spot welding methods are not hard.
