Welding materials and welding of piping nonrotatable joints with narrow grooves for nuclear and thermal power plants

With the aim to enhance labour productivity, reduce electrode and power consumption, ways of reducing sections associated with the manual arc welding of fixed pipe joints are investigated. Parameters are presented for such sections with metal thickness of 17-60 mm and recommendations are provided on the removal of slag. Basic-coating electrodes have been developed for welding equipment from heat-resistant steels
