When you think of welding, the first thing that pops into your mind is joining to metals together. We’ll you’re right, welding in general is all about soldering, and with so many different types of metals, a first timer will have a difficult time in sorting them out.
There are so many different grades that metals are made of and they don’t have the same type of technique.
Steel for example, has 1 percent carbon and are considered difficult to weld because of the property it has as it actually cause cracking problems. Cast iron has 2 percent carbon and can reach up to 4 percent. If that much carbon is present in iron, it easily hardens the material. That is the sole purpose of carbon, it turns into graphite which is praised by many mechanics as it is used as a lubricant on cylinder walls found in a combustion engine.
In welding, carbon and graphite are the toughest to crack. Carbon in high percentages can cause the hardening of the weld metal surrounding the area making matters worse than good.
Another technique to overcome this type of burden is doing Tig Welding. TIG is also known as GTAW short for Gas Tungsten Inert Gas. Just by looking at the name, you can actually see that using this technique involves Tungsten gas to get the job done. So how to TIG Weld? The answer is simple, as it is the same as ordinary welding the only different is that you are using another tool.
There are many materials that can be welded using TIG and one of the most common of which is Stainless and Carbon steel just to name a few. But it is also possible to join other metals like copper and magnesium. TIG is also considered to be one of the highest quality weld that you can achieve.
