Abstract
The results of analysis of ribbed panels used in airframe structures and production experience in the fabrication of airframes by welding ribbed panels to plating by continuous penetration of the plating are used to select the design of experimental ribbed panels of 1561 aluminium alloys for developing production technology. Assembling–welding equipment is constructed and a special tool is used for friction stir welding of T-joints of the ribs with the plating of the panel by continuous penetration of the welding tool into the panel. The welding conditions are determined and experimental full-size ribbed panels are welded.

1. In the industry normative and technical documentations, there is a provision according to which the category of the welded joint takes into account the degree of its liability, determines the type and scope of control of the welded joint and the standard of permissible defects (category III – not involving a product failure).
