TIG Welding Tips for Beginners

TIG Welding Tips

TIG requires plenty of practice to become adept in compared to ARC and MIG welding and you can control the puddle, the arc and the result of the weld better in the case of TIG welding. In this article, we will be discussing a few things that you must keep in mind for proper TIG welding.

Cleaning the Work Surface

For TIG welding, to produce a proper arc and a clean weld, the surface must be very clean. You must ensure that before you start the welding process, the work surface should be cleaned properly. It is a good idea to use a specific stainless-steel brush for the different type of metals you’re welding on and the same brush should not be used to clean the scales and rust of the chassis. The more you clean the work surface area, the better the final welding results will be.

Choosing the Right Tungsten

You may require changing the tungsten depending on the surface you’re working on. Usually, red tungsten is used for steel, while green is used for aluminium. However, you can also make use of purple band E3 tungsten universally for all metals. Also, you must be careful about the size of the tungsten depending on the thickness of the material you are welding. If the tungsten is very large, the heat required in order to strike the arc will be quite high, which could cause the workpiece to warp or burn through. And, if the size of the tungsten is too small, then it can get damaged if overheated.

Touching the Tip, Regrinding

This is the most difficult part of TIG welding. If the tungsten tip is touched in the puddle, it will get contaminated and the tungsten will need regrinding. If the tungsten tip gets contaminated, then the arc begins to wander and it can get difficult to focus the arc on the metal.

Maintaining the Productivity

Here are a few steps you can follow to keep welding without any interruptions. You can keep a few extra tungstens ground and ready to use in case one gets contaminated. Also, keep the workpieces you want to weld cleaned well and within reach. Also, keep several filler rods ready for use when required.

Grinding the Tungstens Properly

A common error that occurs in TIG welding is that the tungstens are not ground properly. Ensure that the tungstens are ground length-wise and evenly. If you grind the tungsten in the opposite way, this will cause the arc to become erratic and start wandering on the workpiece. Make use of a bench grinder that is dedicated only to grind the tungstens on. Using an all-purpose grinder can cause the tungstens to get contaminated.

By following these tips, you can ensure that you get great results when you’re doing your TIG welding, especially if you are a beginner.
