Abstract : The article describes in detail the process of pulse-arc welding of aluminum alloys in the presence of argon as a shielding gas. Parameters of the process are specified. Equipment for a typical welding station is described. It is suggested that regular automatic and semi-automatic machines can be used with only minor modifications, mainly to achieve better feed of the consumable electrode. Sections of the article are devoted to the practice and technique of forming welded seams in various attitudes. Types of electrode wire and care in its storage and use are outlined. The control of parameters of welding is emphasized. Particular attention is devoted to use of the process in the building of ship superstructures. Advantages of the pulse-arc method over customary methods are listed together with a cost comparison of various types of welding. (Author)
