Titanium piping ​has become more popular as more of its favorable attributes are being discovered

Titanium piping has become more popular as more of its favorable attributes are being discovered. Titanium is stronger than aluminum and steel. It is also lighter than steel. It is extremely resistant to corrosion, has a long-use life and low maintenance and operation costs.

If you’ve made the investment of purchasing titanium for you piping project, there are some things to know before you begin to work on it. After all, you don’t want to ruin the titanium that you just spent money on buying. You also want strong pipes that will last many years. Why compromise the effectiveness, strength and durability of your titanium pipes by incorrect welding techniques?

When heated, titanium becomes highly reactive and readily combines with oxygen, nitrogen, hydrogen and carbon to form oxides. Oxidized wields can result in a useless part that needs to be scrapped. To reduce the risk of oxidation, the heated area of the piping needs to be shielded from air until the temperature drops below 800 degrees.

Also, check the purity of the gas. Argon gas is the most commonly used gas with titanium should be no less than 99.995 percent pure and with no more than 5 to 20 parts per millimeter free oxygen. It also must have a dew point greater than -50 to -75 degrees.

A post-flow shielding gas timer is also great to have. Its output should be at least 250 amps.
