Profit & Savings
Precision grinding of electrodes is a smart investment that pays off in both savings and efficiency. By ensuring a correct tip geometry through precise grinding, you optimize welding performance and stability. This not only reduces the need for frequent regrinds but also extends the lifespan of the Tungsten electrode.
Precise grinding
A well-maintained electrode with a smooth surface minimizes material waste, as it enhances the electrode’s longevity and performance. In the long run, the upfront effort of precision grinding translates into cost savings,
less frequent replacements of electrodes, and a more sustainable welding process.
Precise angle of the electrode
When grinding, not only make sure that you have very fine grinding grooves, but also prevent discoloration during grinding of the Tungsten electrode. This discoloration indicates the Tungsten electrode has been too hot and oxide has formed on the surface which will cause poor ignition of the arc. Grind Tungsten electrodes preferably on dedicated diamond discs. This gives a very fine surface to the tip and arc stability.
Consistency
Working with an open belt or bench grinder lacks precision. The welder will need more attempts to get the correct geometry required for the weld. With every regrind comes a loss of app. 1mm-2mm. Using an angle adjustment and clamping system centres the electrode, so that the grinding is carried out in the desired angle and correct longitudinal direction of the electrode.
A precise angle is not only important for the quality of the welding seam; the number of reignitions between regrinding is also increased. The key word here is CONSISTENCY. It is a fact that conventional and manual grinding cannot provide uniform and consistent grinding of Tungsten electrode. For that you will need proper grinding equipment.
Calculate your savings
A Tungsten electrode is a lead actor in the TIG welding process. Before every weld, comes the necessity to grind the Tungsten electrode. Proper geometry is essential to obtain a stable arc and get optimal welding performances
A TIG welder might use one electrode every week, and there might be more than one welder on your team. The cost for a pack of 10 Tungsten electrodes varies between 10 and 100 euros, according to the type and manufacturing of course.
Most of that money spent on Tungsten electrodes is wasted during the grinding process, for multiple reasons:
1. Tungsten electrodes get thrown out when they get an average of 50 mm
2. The grinding lacks precision and therefore requires multiple attempts
3. The tip of the electrode is cut before it is being ground again.
