Common TIG Welding Problems With Their Solutions

TIG welding is used in many high standard welding projects where you have to meet a strict aesthetic standard. However, learning TIG welding is not the easiest things. In fact, it is rated as the most difficult welding method to learn. This is all because the method is really complex.

Here are some of the common TIG welding mistakes, and how you can prevent/ correct them easily.

Problems With Aluminum Rods

Your aluminum bead should appear in a certain way no matter what manufacturer you have bought it from. However, the filler metal problems can cause the aluminum to look grainy. Aluminum today from one manufacturer might have completely different properties from the other manufacturer. That is why you should choose one filler brand for your project. There can also be other problems with the welding equipment.

That is why before welding, you must choose the right type of filler material and clean the surface before starting. This is the easiest way to prevent contamination.

Craters

Craters are one of the most common problems that welders face while doing their work. These craters usually develop towards the end of your welding work. This might happen if you decrease the welding power too quickly  as it allows the materials to cool down quickly. Removing the filler rod too  quickly can also cause the same issue.

You can easily prevent this by keeping the filler rod in place while slowly decreasing the welding power at the end of a welding session. Sole TIG welders now already come with crater control settings. They automatically slow down the welding process towards the end. This makes the bead look good.
