Tungsten Electrodes For TIG Welding What’s the Big Offer With Sharpening?

Tungsten electrodes are offered in Thoriated, lanthanated, ceriated, and a handful of other kinds. When you are welding steel, they all have a single issue in widespread.

They need to be sharp. But is it truly that essential to sharpen them the way the welding textbooks illustrate?

I have been TIG welding for more than thirty many years and have sharpened tungsten electrodes all varieties of techniques. Even with a reducing torch. Thats appropriate I explained cutting torch. I dont recommend it, but it does perform. I have also used Chem-Sharp, belt sanders, tiny ninety die grinders, bench grinders, large electric grinders, and even the new large dollar tungsten electrode grinders.

The bottom line is this. Except if you are welding razor blades, a great deal of the anal retentive textbook strategies for sharpening tungsten electrodes just will not make much variation. I know I am going to get a great deal of loathe mail more than this but it is just basic genuine. Like most welders, I was taught in welding school that a bench grinder with a stone devoted solely for tungsten was the only way to sharpen tungsten. And that all the scratches from grinding had to run parallel with the electrode.

Then I received a career.

The true world has a way of separating the BS from the down and dirty things that actually operates and Its kind of difficult to sharpen a tungsten to textbook standards when you are up sixty feet in the air on a scaffold and want to tie in a weld prior to the up coming wave of steam leaks prior the safety valve. And If you have a small grinder in your instrument bucket you do the math pretty fast and give it a attempt. I learned speedily that as prolonged as I utilized a smooth enough grinding disc, spiraling grinding marks be damned, every little thing turned out good. A couple of hundred excellent x rays with out a tungsten grinder also have a tendency to make you believe you are not doing almost everything improper.

So is this whole tungsten electrode sharpening thing getting Large-Dealed?

Indeed and No. It undoubtedly sells tungsten sharpeners.

Critically, I can feel of a number of apps in which textbook tungsten sharpening is critical . Razor blade form thicknesses would be one particular, Yet another illustration is for automated processes like orbital TIG welding. In orbital TIG welding it is quite widespread to sign up for stainless or titanium tubing that is only &frac14 ” in diameter with wall thickness of less than .030″. Amperage for these form welds is very lower and even small changes in tungsten electrode preparation can really make a big difference. Given that the geometry of an electrode suggestion definitely does have an influence on the arc, you will want to use a special tungsten grinder to get every taper and tip steady so that when one thing goes mistaken, you can eradicate tungsten preparation as a variable.

But If you are TIG welding some thing like a 1/eight” thick bracket for a set of headers, Do not sweat it. Just use a clean sharp electrode sharpened nonetheless you select and weld the canine crap out of it.
