What are the main points of titanium tube welding?
The inner and outer surfaces of the groove and its sides are cleaned up within 50mm, and the cleaning procedure is as follows: Grinding machine Grinding machine → Sanding paper polishing → Acetone cleaning. After cleaning can not be directly welding operations, to be the end of the groove to dry after the operation. If the time is more than 2 hours, it must be re-cleaned or protected by self-adhesive tape and plastic cloth
Welding wire: ERTi-2; welding method: GTAW (manual TIG welding), protective gas: with 99.995% purity, water content should not be greater than 50Mg% m3 of argon, welding pool and welding joints inside and outside the surface temperature Areas above 400 ° C are protected by argon
The wire is also wiped with a sponge with acetone and stored in a dedicated wire box. The operator must wear clean gloves in the welding
Groove processing, titanium tube cutting, the use of alumina grinding machine grinding out the groove, as shown below, processing groove does not allow the parent material to produce overheating discoloration.
