Physical-chemical principles of a new process for plasma-arc welding of large-size electrodes to metals with no shielding of the welding zone from air, as well as designs of welded joints developed for electric contacts, are described. It is shown by an example of aluminium electrolytic cells and thermal-electric furnaces for graphitisation and synthesis of silicon carbide how the new welding process can help save electric power in production of primary aluminium, magnesium and graphitised electrodes, replace copper bus systems of furnaces by the aluminium ones, and develop new upgraded designs of electric assemblies. The book is intended for engineers and technicians involved in the problem of energy saving, as well as welding and electrical engineers. Also, it can be helpful for university and college students studying the corresponding specialities..
