How to Weld Titanium Pipe

Titanium pipe welding process is in the atmosphere using manual tungsten inert gas shielded welding (GTAW) welding method. Welding on the titanium pipe groove and its sides on both sides of the 25mm inside and outside the surface to remove oil, the application of austenitic stainless steel wire brush, reamer and other mechanical methods to remove its oxide film, burrs and surface defects. The cleaning tool should be dedicated and kept clean; the surface of the groove after mechanical cleaning and the filling of the welding wire should be degreased before welding with acetone or ethanol without sulfur. Welding process, the use of special protective measures, the titanium pipe welding area temperature may exceed 400 ℃ part of the local or all in the effective protection of argon, titanium pipe to achieve the purpose of welding.
