The process of welding became very popular in the 19th century when it started being utilised by the military. Today, welding is a very popular technique that is utilised by several industries. The two most common methods of welding are TIG and MIG welding.
In the process of TIG welding, a tungsten electrode is used to produce the electric arc for the process of welding. TIG welding does not require the addition of metal for the weld, which can be added by making use of a separate filler rod. In TIG welding, an electric current passes via the electrode’s metal tip. It is possible to do TIG welding both manually, as well as automatically.
Metal Inert Gas welding is also called GMAW or gas metal arc welding. This process was invented during the WWII and was used to produce equipment and weaponry very quickly. The process of MIG welding makes use of an electric arc which produces a short circuit between the cathode and anode. When this occurs, it generates heat and a gas that is non-reactive, which causes the metal to melt and fuse together. When the source of heat is taken away, the metal solidifies after cooling and a new metal is formed. The process of MIG welding can either be an automatic process or it can also be done semi-automatically, where it needs an operator to operate the welding gun.
TIG vs MIG Welding
Although the TIG welding process is used quite commonly, both the processes of welding, MIG and TIG have their pluses. MIG welding lets you weld various types of metals and you can also weld thin to thick metals using this process. The MIG welding process is also easier, as the electrodes are added to the weld.
On the other hand, TIG welding produces a neater and more accurate weld compared to MIG welding and is a more popular process compared to other welding processes. Also, TIG welding does not generate any splatter and sparks. In addition, the argon that is utilised for TIG welding shields the puddle and there no need to use a slag, which can cause the view to be obstructed.
The processes of MIG and TIG welding cannot be interchanged and each is used for different applications. While TIG welding is suitable for smaller jobs such as welding a lawn mower, bicycle frame, gunsmithing, etc. and the process works better in the case of metals like gold, brass, nickel and copper alloys, MIG welding is a better option for larger jobs such as vehicle bodywork.
So, the job at hand and the requirement of the job really determines if you must make use of TIG welding or MIG welding for the particular task.
