It consists of heating fields A,B,C, translating to one another, while boundaries of these fields are matched with boundaries of fragments 8 of both buses 3. One contact wire 4 is held in field A on free end of fragment 8 of one bus 3 matched with it, and another one - in field E at given distance from free end 9 of same fragment 8 of another bus 3. This provides for similar and constant heating temperature in fields A,B and in field C up to position where wire 4 is held, and from aforementioned position to the end of field C - alternating (descending), thus confirming possibility of production of both one needed temperature and a range of temperatures in local zone of heating surface of element 1. Flexible electric heater 11 (dwg.2) contains, encased in polymer casing 12, laminated cloth resistive element 1, current-conductive screen 13 and a layer of cloth material 14. Electric heater may contain two or more cloth resistive elements in case of their serial, parallel or serial-parallel connection and may support given heating mode with constant and alternating temperatures across its whole area.

EFFECT: expanded operational capabilities, simplified construction of electric heater.

FIELD: chemistry.

SUBSTANCE: method involves applying coating material onto a metal substrate using a knife coater, by dipping, spray-lacquering, using rolls, by soaking or pouring. The coating material contains an easily oxidisable organic or organo-inorganic binder, with easily oxidisable organic components, and electroconductive metallic or non-metal filler. In order to ensure capacity for bonding, the binder also contains compounds which, when heated in reducing conditions at 840°C, form an electroconductive phase. The coating material can contain electroconductive compounds which are resistant to oxidative processes at high temperature, as well as lubricants, pigments, grease and metals. The metal substrate used is steel, a steel alloy or steel with a metal coating. After applying the coating material onto the substrate, the composite coating material/substrate is heated to temperature 600-1300°C. The applied coating layer changes its structure and serves as an adhesive underlayer for other coating materials.

EFFECT: obtained layer structure has sufficient electroconductivity, needed for application in common types welding, particularly dot welding.
