Abstract
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 3 to 10 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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
94 words
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 3 to 10 5 W/cm 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.
Claim 2
Independent Claim
94 words
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 3 to 10 5 W/cm 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.
Claim 3
Dependent Claim
17 words
The method of claim 1 in which the alloy element has a higher melting point than aluminum.
Claim 4
Dependent Claim
17 words
The method of claim 1 in which the alloy element is iron, nickel, cobalt, manganese or chromium.
Claim 5
Dependent Claim
25 words
The method of claim 1 in which the remelting of the deposited surfacing material is accomplished without addition of surfacing material to the weld pool.
Claim 6
Dependent Claim
25 words
The method of claim 1 in which the volume of the weld pool is increased by decreasing the speed of deposition of the surfacing material.
