Abstract: Titanium has the widest application of all reactive metals. The basic properties of titanium are good corrosion resistance and an excellent strength-to-weight ratio. It is applied in: chemical industry, aviation, rocket technology, medicine, etc. With development of metallurgy of titanium production, its price became much more accessible, but it is still very high, the welding repair is therefore applied wherever possible. Welding is also significantly used for the production of machine parts. This paper presents a detailed procedure of reactor vessel production for obtaining chlorinedioxide (CiO2) in the chemical industry PULP-Viskoza. The reactor is made from a titanium-clad steel plate. Explosive cladding and the principle of clad welding (bonding of elements) are described. Prior to the onset of the reactor production, the tests of titanium/steel bonding by explosive cladding were made for defining the required parameters. The plates were cut from the trial cladding, and inspected by ultrasound and penetrant testing followed by trial welding, resulting in the final selection of welding parameters. Relaxation of cladding from the residual tension was made in the furnace without air removal in order to determine the condition in which the titanium will be after heat treatment.
