Welders are responsible for repairing structures all over the world and from space to deep in the oceans. Welding is seemingly a simple process of joining two metals together but it requires a variety of techniques to be successful. Arc welding is one of the most common classes of welding and is the most basic form of welding. This is where you should start if you are a beginner. This includes a number of welding methods like stick welding, tungsten inert gas welding, and metal inert gas welding. These are methods used frequently in the industry.
Stick Welding-This can also be called shielded metal arc welding. It is widely used and one of the oldest techniques because it is so simple. It is not affected by the wind like TIG or MIG welding because of their gas cylinders and that makes it a very popular choice when working outdoors. You can perform this type of weld by creating an electric arc between a metal electrode and your workpiece. The current that travels through the electrode melts it so you are left with a weld pool on your workpiece. The electrode also has a flux coating that melts down, safeguarding your weld from corrosion. Similarly, shielding gas protects your welds in TIG and MIG welding. A protective layer is created when the flux melts and forms a slag layer over your weld bead. This should be removed once your weld has cooled.
MIG Welding-This is also known as gas metal arc welding. MIG stands for metal inert gas. This type of welding is also popular because of its ease for beginners, being suited well for work on auto parts and home repair jobs. MIG welding is typically used to joining low-alloy steels. An arc is created between a wire electrode and your workpiece and melts the wire electrode slowly, which creates the weld joint. You can accurately feed the wire electrode with an electrode gun. This is linked to the welding machine. This gun also can release controlled amounts of shielding gas, safeguarding your weld pool from contamination. Some of the benefits of MIG welding are its ease of use and high productivity.
TIG Welding-TIG stands for tungsten inert gas. You use an electrode to create an arc that heats metal to the melting point. Shielding gas gets directed at the weld pool keeping it safe from the atmosphere. TIG welding is known for high-quality welds. It is one of the more difficult processes as it requires you to hold the TIG torch in one hand and feed filler material with the other. It requires high manual dexterity and you must be able to use both hands together at once. TIG welding provides extremely precise welds and can be used for a wide range of metals like nickel alloys, aluminum, copper, bronze, and brass. It doesn’t rely on flux material so there is no danger of corrosion and no slag is created eliminating post-weld clean up. No sparks are created in the process, either.
If you are looking to get into welding, there are the places you must start. Determine what types of projects you want to work on and do some additional research to decide what style of welding you should start learning. And remember, if you are cutting materials to weld, nothing cuts like a KAMA. Eliminating the need for grinding and sanding your edges saves you loads of time on your projects!
