TIG welding

RKD Machine Shop Services are the specialist in MIG and TIG welding, as well as precision machining techniques. They have worked on a wide range of projects in the past, so whatever prototype, bespoke component or machined part you need, they can help you by providing the design and machining expertise you need. They pride themselves in using high quality, precision techniques, the best materials, and always working to deadlines. This means that you can be confident that you will receive what you need, when you need it.
What is TIG welding?
The ‘TIG’ in TIG welding stands for tungsten inert gas welding. It works by creating an arc from a welding torch with a tungsten electrode to the metal surface that is being joined. This arc, which is essentially a short circuit, creates heat. The heat is used to melt a filler metal wire which is fed continuously into the joint. As it melts, the filler wire fills the joint. Once the heat is removed, the filler metal solidifies, creating a strong joint.
Whilst this is happening, an inert gas like argon is sprayed over the joint. This prevents the oxygen in the air from reacting with the molten filler and oxidising. This means that the finished joint is stronger than if air was in contact during the process.
What is the difference between MIG and TIG welding?
In basics, MIG and TIG welding are similar. Both use a type of welding gun and rely on an electrical arc to generate the heat. In each method, inert gas is used to shelter the joint from oxidisation until it has cooled. The main difference is that with MIG welding, the electrode is itself consumed to make the joint, whereas with TIG welding the tungsten electrode is not melted, but rather a filler rod is continuously fed into the joint.
Does your project need MIG or TIG welding?
MIG welding and TIG welding have different features which make one or other better in different projects. In general, MIG welding is faster than TIG welding. This means that if the main priority is speed, TIG welding may not be the best option. Having said that, TIG welding is not a lot slower, so this is not the only factor to consider. TIG welding offers greater control, precision and neatness. This means that if the appearance of the finished joint is your main priority, TIG welding may be the best option. As with speed, this is not an absolute rule, as MIG welding can be used to do tidy welding. Another factor is the strength. In general, TIG welding produces a stronger joint than MIG welding.
Fortunately, you do not need to be able to choose between MIG and TIG welding. RDK Machine Shop Services are the leading expert for both MIG and TIG welding. This means that they can do whichever method is best for your needs.
