Welding titanium tubing requires extreme cleannessthe base metal filler metal and welding environment must be immaculate. Contamination by natural body oils oils from the forming and drawing process shop dust paint dirt cutting fluids and lubricants all can lead to embrittlement and weld.

Well-designed and -maintained purges on both sides of the part to distribute the argon evenly. Grind slowly to minimize heat input. After pickling rinse the parts in hot water.

Be Sure to Properly Shield Gas. I recommend carrying one. However TIG welding can be very challenging if done manually and the challenge is only heightened for tubing applications.

Like aluminum titanium features oxides that must be removed prior to welding. Titanium can ONLY be welded to Titanium or Titanium Alloys. The white-glove treatment after thorough cleaning.

Our lead fabricator Vihn takes you through the entire process from prep to perfect when it comes to welding Titanium. Use a small hot-air blower to ensure that theres no moisture left on the surface. The Best Orbital Processes for TIG Welding Titanium Tubes TIG welding is the preferred technique when the highest quality welds like those required for titanium tubes are necessary.

The most preferred welding method for titanium is TIG welding but you can also use MIG welding for fairly thicker plates. You can TIG weld titanium. However make sure that you dont use it on any flammable.

Grind or file both the inner and outside surface of the pipe 1-inch back from the joint as well as the actual edge that will butt against the other piece. According to some sources it can be soldered too but it is not simple.

For example in the case of a 3 tube diameter and a 114D bend radius it would give us a CLR of 342. If you get any discoloration other than slight straw you may not have good enough argon shielding to weld titanium or anything else. Its best to use chemicals specifically designed for titanium.

German PUK 5 precision TIG welder and US made Orion precise TIG welder are two brands. Starting off by describing and. Tight and Loose Radius Difference -We calculate CLR Center Line Radius of a bend by taking the diameter of the tube and multiplying it by the radius of the bend.

Titanium tube weld defects are due to the titanium tube welding argon arc welding gun formed by the formation of argon gas maintenance layer can only maintain the weld pool from the harmful effects of air and has been solidified in the vicinity of the high temperature weld and There is no protective effect in the vicinity but the titanium pipe weld and its vicinity in this state still have strong. You just puddle a small area for a few seconds and then terminate the arc and hold the torch still. Clean welded titanium pipes with light oxide scaling by acid pickling.

To remove the contaminants you can use a steam cleaner or a diluted solution of sodium hydroxide.
