STUDY AND DEVELOPMENT OF WELDING MATERIAL AND OF RESISTANCE WELDING PROCESS TO MAKI STEEL-LEAD COMPOSITIONS

There the formation mechanism of joint zone in the steel-lead clad metal made by the resistance welding, which was based on the formation of metallic bond between the components of welding material and the lead, on the wetting of steel with the lead melt, has been ascertained. The welding material of Mn-Ni-CuCl*002 system has been developed, the optimum modes of welding according to the given resistance of lead - steel zone of contact have been determined by means of heat simulator. The tinless welding material, the process of resistance welding of lead with steel have been introduced. The steel - lead sheet clad metal made by resistance welding has been applied in the construction of electric precipitators at the Joint-Stock Company of Closed Type "Khimprom", Volgograd. The application fields are the chemical machine-building, the radiation shielding, the special van buildingAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
