Problems of welding titanium and titanium alloys, without the usage of special vacuum or inert atmosphere chambers, is expressed in welding repairs where parts may be different sizes and shapes. It would be too expensive to construct a protective atmosphere chamber for each individual case. Chambers usually are awkward for welders and also limit the process control. The purpose of this work is to find out the possibilities for performing quality repairs without the use of the special chamber. The practical part of our work deals with repair welding of clincker furnace camera case in a cement factory. The extreme working conditions lead to intensive wear of the camera case. Depending on the location in the clinker furance it needs to be changed or repaired after 6-12 months of exploitation. Repair is done by TIG welding process using dual secondary weld protection (face and root) with argon. The microstructure of the samples was analysed, and also hardness tests were done on the base material, heat affected zone and the weld. The study showed no significant changes in the microstructure of welds in relation to the base material, and the results of hardness tests were fairly uniform. After acceptable testing results the repair of camera case was done. The repaired camera case had the same expaltation life as the new case. This indicates that the repairs were carried out successfully.
