Research on Materials for Submerged Arc Welding of Titanium.

摘要

This report presents the results of a study of halides as candidate materials for submerged arc welding of titanium alloys. Criteria are defined for optimum performance and tests are performed to screen candidate fluxes. CaF2-base fused fluxes are determined to offer preferred welding characteristics. Four promising compositions are identified: CaF2, CaF2-(5%)BaCl2, CaF2-(5%) SrF2. SrCl2 and CaF2-(5%)BaCl2-(2%)LiF. Groove welds were made with CaF2 flux and Ti-6Al-2Cb-1Ta-1Mo wire.
