Abstract

A method of depositing a layer of a metal other than aluminium onto an aluminium-base alloy with the use of surfacing material based on alloying element, wherein the deposition process is conducted at a heat output of the heat source of from 10.sup.3 to 10.sup.5 W per sq cm and the surfacing material being added to the welding pool in an amount of from 20 to 98% by weight, whereafter the metal thus deposited is remelted, with the weld pool volume being increased 1.2-10.0 times each time when the deposited metal is remelted.

Dependent claims

A method of depositing a layer of a metal other than aluminum onto an aluminum-based alloy, comprising:

(a) introducing into a weld pool about 20 to 98% by weight of a surfacing material based on alloying elements;
(b) depositing said surfacing material onto said aluminum-based alloy from said weld pool using a heat source having a heat output from 10.sup.3 to 10.sup.5 W/cm.sup.2 ;
and
(c) remelting the deposited surfacing material while increasing the volume of the weld pool 1.2 to 10 times each time the deposited surfacing material is remelted.
