CS240417B1 - Method of another metal layer building-up on aluminium - Google Patents

Abstract

The invention relates to welding technology and can be used in all national areas farms where structures are constructed made of aluminum alloys. The object of the invention is to increase the weldability by increasing wear resistance welded layers when welding aluminum on materials from the group of iron elements providing reduce your own costs. The goal is achieved by the fact that first, the layer is welded with a stream that is is 1.5 to 3 times larger than the current used for a given thickness, and at a speed that is higher with respect to the speeds for the given Thickness 3 to 10th, taking the first the layer is fed with the weld metal in an amount 20 to 90% of the welding bath and then remelting the weld metal at an increased volume of welding bath 1.2 to 5 times.

BACKGROUND OF THE INVENTION Method for Welding Another Metal to Aluminum with Welding Wire, characterized in that in order to improve the quality of the weld, the wear resistance of the welded layer is increased in the process of welding the iron group to the aluminum by first welding the layer with a jet. which is 1.5 to 3 times larger than the current used by the sold thickness and at a rate which is higher with respect to the speeds for the thickness 3 to 10, wherein the welded metal is fed to the first layer in an amount of 20 to 90% of the welded web and then re-melted. metal at 1.2 to 5 times the weld pool volume. Recognized by the invention on the basis of the results of expertise, conducted by the State Committee for Inventions and Discoveries of the USSR, Moscow, SU,
