MIG = Metal Inert Gas This technique covers the welding with a special gaseous byproduct. TIG: Tungsten Inert Gas welding. Unlike with spray transfer, gas is also used to shield the weld but it uses a different process. Each method has its own benefits and is utilized with varying types of projects.
MIG welding would involve the feed in of thin wire used within a welding gun. When these wires are heated they melt and adhere to a metal you are working on. Meanwhile, an inert gas exits the gun to protect the weld puddle. The purpose of this gas is to keep the weld neat and free from contamination. One of the best things about MIG welding is that for beginners, it has a reputation as one of the fastest and easiest forms to learn. It is a great option for welding thick pieces of metal such as sections of 8 steel.
TIG is a more complicated welding tool compared to MIG that offers better precision and control. TIG welding requires loads of hours of practice and skill. A tungsten electrode makes contact with the metal that you are welding and this is how the helium arc welder works. The metal is melted by this hot electrode. A filler rod is needed to actually connect the pieces. The TIG welding process is famous for producing very high strength, superior quality welds it also better suited to thin metal sections and aluminium.
If you are planning to begin welding, knowing the fundamentals of both MIG and TIG is important. This is a list of some necessary tools, like welding gun, ground clamp to connect the circuit and shielding gas for weld protection. Safety first, safety always- gloves, eye and face protection (welding helmet).
The MIG welding is a popular method in the field of fine arts because it requires only two weeks to master this technique. And you can get started in a couple hours. Then you'll have to select the proper wire size for your project and probably a few settings on your welding equipment. What helps to get better welding results is proper position of the gun and distance from metal.
TIG welding, on the other hand will take a lot more practice and skill to get perfect at it. Just like MIG welding, you will need to select the right tungsten electrode for your job and make sure all of your settings are correct. Keep your welding gun at the correct angle and distance from the metal when welding.
The decision to MIG weld or TIG weld comes down to what you want out of your particular project. Because MIG welds faster and is typically easier to use, it works well for bigger pieces of metal and projects where time is more critical. TIG requires more skill, but it makes better welds — in particular for thin metals that need fine precision because they are less likely to burn through.
