A procedure was developed that allows an experimental determination of a correlation between an increased oxygen concentration in the argon of welding torch, intensity of radiation of atomic oxygen lines OI in the arc and the corresponding change in the properties of welds in a real-time welding of titanium. It was found that an increase in oxygen content in argon to 0.34 vol. % during violation of the weld protection leads to an increase in the tensile strength of the weld metal by 30% and at the same time reduction in the ductility by 65%. The proposed procedure can be used to create a database in the development of systems for predicting operational reliability of welded structures of titanium alloys by quantitative indices of changes in the characteristics of the weld metal during welding.
