How To Weld Titanium Pipe

Using a filler rod other than titanium like stainless steel or nickel alloy rod. This will help prevent contamination of the weld pool via the filler rod.

Pros of Welding With Titanium.

How to weld titanium pipe. 7 rows Specification Seamless Pipe Specification Welded Pipe Specification CondensersHeat. And the technique of holding the torch in place until the metal has cooled below 500 degrees F should produce a clean silver-colored titanium weld every time. For welding titanium you should use a 2 Ceriated Tungsten electrode.

Titanium Butt Weld Pipe Fittings. 40 lighter than steel high tensile strength. Clean work areas free of combustible grinding debris.

Titanium Flow always stocks titanium pipe product fittings such as ASTM B-363 WPT2W to compliment the pipe inventory. 116 inch or smaller for welding at less than 125 amps 116 to 332 inch for 125 to 200 amps For greater than 200 amps you should use an electrode of around 332 to 18 inch in diameter. When heated titanium becomes highly reactive and readily combines with oxygen nitrogen hydrogen and carbon to form oxides.

Although titanium has a reputation for being difficult to weld it doesnt have to be problematic. Because of the reactive nature of titanium these particles will combust spontaneously upon exposure to atmospheric oxygen once outside the protective weld. I have uploaded this video twice however the other video has certain songs that unfortunately will not allow the video to play on certain devices so.

Tink tink tink you can actually break the weld by tapping it lightly with a ball peen and man is it brittle. Clean the outside of the titanium tubing by using a stainless-steel brush and when welding it is recommended to use the dab technique to help bolster the mass of the pipe. Make use of a large gas lens with a diameter of a minimum of 075 to 1 inch.

Titanium is as strong as steel nearly half its weight and highly resistant to corrosion which makes it a highly desirable cost-effective choice for industry especially defense and aerospace. Well-designed and -maintained purges on both sides of the part to distribute the argon evenly. The most preferred welding method for titanium is TIG welding but you can also use MIG welding for fairly thicker plates.

We typically dont recommend adding filler metal until thicknesses exceed 5 millimeters although AWS D106 recommends a v-groove on thicknesses exceeding 24 millimeters and a u-groove on thicknesses exceeding 95. Ad High Performance Wide Range Structural Adhesives Bonding Plastic and Metal. The S schedules for stainless steel apply to the wall thickness for all butt weld pipe fittings.

30 or better strength to weight ratio over aluminum or steel. Paying close attention to filler metal selection cleanness and use of the shielding gas are three steps to successful GTAW on titanium tube and pipe. For welding titanium you must make use of a 2 Ceriated Tungsten electrode 116 inch or smaller sized for welding at less than 125 amps 116 to 332 inch for 125 to 200 amps.

GMAW produces a titanium vapor in the weld arc that deposits onto the cooler weld surface as finely divided titanium particles. When beginning to weld clip off the end of the filler rod before every use. Remember to always use 99999 pure argon as this is the best way to avoiding contamination and ensure that your titanium welds turn out as desired.

Clean the outside how to weld titanium exhaust the titanium tubing by using a stainless-steel brush and when welding it is recommended to use the dab technique to help bolster the mass of the pipe. As a general rule of thumb we recommend that titanium tube or pipe thinner than 5 millimeters should be welded autogenously square butt joint no filler metal added. For higher than 200 amps you ought to use an electrode of around 332 to 18 inch in size.

If you weld titanium with anything other than titanium you will hear the sound of the weld cracking like glass. The white-glove treatment after thorough cleaning.
