The welding process of titanium pipes is a manual tungsten inert gas shielded welding (GTAW) welding method in the atmosphere. Before welding, the titanium tube groove and the inner and outer surfaces of each side within 25mm are cleaned of oil stains, and then austenitic stainless steel wire brush, reamer and other mechanical methods are used to remove its oxide film, burrs and surface defects. The cleaning tool should be dedicated and kept clean; after the mechanical cleaning, the surface of the groove and the filler wire should be degreased using sulfur-free acetone or ethanol before welding. During the welding process, special protective measures are adopted so that the part or all of the temperature of the welding zone of the titanium tube may exceed 400 ° C. Part or all of it is under the effective protection of argon gas to achieve the purpose of welding the titanium tube.
