Welcome to part 5 of our welding series. Today we are going to be taking a quick look at TIG welding what is and how it works. TIG actually stands for Tungsten Inert Gas. It is very capable of producing quality precision welding jobs.
TIG welding works by producing an ARC between the metal you are welding and the Tungsten electrode. It is important to note that Tungsten electrodes are non-consumable. Gas is used around the molten pool to shield it from impurities and is fed through a torch to the area in question. Sometimes filler wire is added to the weld pool and in these cases it is added separately.
If you are thinking of using a TIG welder then are a few things that you should consider. They are quite expensive when welding thicker sections and require a great deal of skill compared with some of the other methods of welding. An AC/DC TIG unit is required for welding aluminium as opposed to the DC TIG used for other metals. In saying that though TIG welding will produce a superior quality weld. You will find that they have very good heat control and are generally free of splatter and distortion.
You will generally be able to find three types of starter systems when it comes to TIG welders; Scratch Start (the basic), Lift ARC and High Frequency (HF). One great thing is that the majority of TIG welding sytems will also come with an ARC welding capability also.
If you are looking for quality, precision welds on stainless steel, aluminium or copper alloys and you have the skill and the budget, you may consider a TIG welder. We hope you enjoyed learning about TIG welding and would also like to remind you to check out the other parts of our welding series if you havent already.
