Do you know how to prepare the electrode tip for TIG welding? So, come with us because, in today’s video, tungco.com will talk about: How to prepare the Tungsten Electrode Tip in the TIG Process.
Today we’re going to do a special edition to answer some questions that arose about the video of electrodes released on the channel. The TIG process is clean as it does not generate fumes, spatter, or slag that other processes cause. But, if the Tungsten Electrode used does not have its end or tip prepared correctly, the welder will have many difficulties controlling the arc.
The Tungsten tip with Welding Grade Carbide Grit must be prepared according to the type of current and equipment technology used. This is because, in older sources, the indication is to use the Tungsten Electrode, with a green tip, when welding in Alternating Current, in Aluminum, for example, and in this case, no preparation of Tungsten is done. In Inverting sources, it is preferable to use Golden, Yellow, Blue, Purple, or Red Tip electrodes.
When welding with Direct Current, Carbon Steel, and Stainless Steel, it is necessary to prepare the Tungsten end to obtain the best control and direction of the arc energy. Applying the Red, Purple, Blue, Gold, or Yellow Tip Electrodes is recommended.
Sharpening the tip is extremely important and must be done using specific equipment or on emery with a drill sharpening stone. The sharpening must be done in the longitudinal direction of the electrode. Not literally, as this marks the surface of the Tungsten, and the arc will be “spinning” at the end, causing discomfort to the user and not focusing on the joint. The sharpening angle is very important as it interferes with the penetration and shape of the weld bead. The higher the sharpening quality, the better the arc’s stability and the Tungsten’s duration.
Finally, after sharpening, it is important to remove the tip, which is usually very sharp. Place it against the grinding wheel and remove approximately 0.3 to 0.5mm from this tip. This causes the arc to focus at the end of the electrode and have the energy better directed at the joint. Always wear Protective Eyewear and an appropriate respirator.
This tip can also be prepared in electrodes used for welding in Alternating Current and when using sources with Inverting Technology. Facilitates operation and penetration.
