There are a lot of forms of welding as of today. To be more specific Mig is one and tig is another and so on. See mig and tig are very different even though they are spelled closely alike. You may think that welding is hot, because you see a lot of sparks flying everywhere. Well you are right if you thought that. So you probably heard the saying “if you can not stand the heat, stay out of the kitchen”.

Mig stands for metal inert gas. It is a welding process in which an electric arc is formed between a consumable wire electrode and the work piece metal. Many use mig because it is a fast process over all. I would say it is less time consuming and a lot cleaner compared to flux core welding. With mig, the wire is feed through the gun. Along with the wire electrode, a shielding gas is fed through the welding gun, which shields the process from contaminants in the air.

Tig stands for tungsten inert gas. It is welding process that uses a nonconsumable tungsten electrode to produce the weld. You would have to hold this electrode manually unlike tig which it is feed through the wire. It is a very clean process nothing like the rest. It is a little slow, but it is an ok process with me. Did I mention there are no sparks invovled! Wow! Welding with no sparks, now that is a plus. You would not have to worry about any sparks going down your back!

So which would you pick? Mig? Tig? They are not that much different because they both include heat. They both include a bright light. They both include gas. They both join metal together. Tig would be better for you if like a smooth welding process. Mig would be better if you prefer a faster process.

They have a lot in common, but they are so different. Tig is more complex and difficult to master. Mig is the most common industrial welding process because of its speed. Tig is significantly slower than most other welding techniques. With mig the primary cause of porosity is gas entrapment in the weld pool. This occurs when the metal solidifies before the gas escapes. With tig weld quality will be good by maintaining cleanliness so it would not lead to porosity.

With these two processes comes great responsibility. When welding you should wear protective clothing, including heavy leather gloves and protective long sleeve jackets, to avoid exposure to extreme heat and flames. You should always wear steel toe booths to protect your feet. You should wear safety glasses, always, to protect your vision.

So mig is the fastest process in welding. Tig is a very time consuming process, but very clean. Mig produce sparks, but tig does not produce sparks. There still has to be safety involved. No matter which you prefer you have to be safe doing what you do best.
