Tig welding Titanium is not easy

Tig welding Titanium is sometimes easy but can prove difficult as well. Efforts required in this technique are more and it demands lots of it.

It requires looking after number of things and taken care of to soothe the process as compared to Tig welding stainless steel. While the weld is in process, there is a higher possibility of the rod getting sticky and it tends to stick on the edges of the weld. To avoid this, the rod can be fed exactly in the centre of the hottest area of the weld puddle.

To carry out this welding technique efficiently the most important thing that should be taken into consideration is “clean” factor. Whenever you are about weld Titanium, make sure it is clean from dirt like several coatings, grease, oil and oxides deposited on Titanium before begin with welding. If the surface of Titanium is left oily or greasy, it will become porous and becomes visible in X-ray negative of the weld. The porosity can give rise to problems.

Issues coming with Titanium welding and Pollution

If you are using any other rod made of nickel alloy and stainless steel while welding Titanium, you might hear the sound of breaking the glass. It actually happened when such rods are used in combination with Titanium. You can literally break the weld by just tapping it gently with some pointed substance and you’ll see the brittle nature of the weld.

Protecting the weld becomes very important as the material gets very thin when treated with extreme heat conditions so either sides of the weld should be covered with Argon to prevent it from becoming brittle. The exterior part of the Titanium weld is delicate due the welding process and thus should be protected with Argon. In the absence of shielding gas the weld becomes brittle.

The nozzle has to be used of diameter#7 will help in protecting the hot part of the weld in some amount.

Titanium tends to draw in different components such as nitrogen and air at certain temperature. However, 800 degrees F is the limit where it is maintained safe only when protected with Argon.

If you are thinking of discoloring the Titanium, it is not an issue. However, it might create some problems which come in sequence of: hay, brownish, violet, blue, salmon pink, grayish along with oxide flakes. The colors mentioned should follow the sequence exactly as these are stages occur while staining eth weld.

Also, it might happen that due to change in welding requirements the hay color is not displayed. However, bluish color is also seen in some shades during staining. It is fine if the weld is giving silverfish shade. The welding side should show the brownish or hay color during staining process. The staining process is carried out to prevent the pollution occurring due to air. The cleaning process is important to obtain good Titanium weld.

Don’t even think of preparing Titanium cover box for welding instead go for blast cupboard and make it your specification, it would be preferable.

Don’t even consider assembling the things on your own as you might spend hefty bucks in buying the metal required, bend it, get it welded, buying the safety gloves and make them fit in plexi-glass. So avoid doing it on your own.

Later you will require is a device for inspection and certain other stuff like shielding gas extractor or diffuser and grounding tab and now you are ready for keeping tig welding and then go through the webpage. To carry out the welding stuff safely make sure you are checking out the protection is all good and then only make use of new nozzles or homemade ones as per your convenience. Titanium discs are very important and helpful in welding inside the chamber using oversized cups and outside as well.

This way is extremely functional to ensure that the protecting gas that is expelled out is of fine quality irrespective of the type of steel that is welded. There will be a problem for short period but you can keep the flash still after stopping the arc. You can get a color other than light hay then probably the argon used for shielding is not sufficient required for Titanium weld or some other.
