Specific embodiment
A kind of arc-welding increasing material manufacturing Al alloy powder core filaments of the invention, the section of structure is as shown in Figure 1, include that aluminium closes
Golden metal sheath 1 and powder core 2 contain one or more of the second major element barium, strontium or calcium in the powder core 2.
Arc-welding increasing material manufacturing Al alloy powder core filaments of the invention, Al-alloy metal crust can be used and conventional metals
Core wire manufactures similar line manufacturing equipment and condition to manufacture, for example, aluminium strip is made up of forming roller.Aluminium strip can be by
Aluminum or aluminum alloy is made.Such as 4000 and 5000 series alloys, two kinds of alloys for being particularly suitable for forming band are 5052 and 5056 aluminium
Alloy.Aluminium strip can use different sizes as needed, in the present invention it is preferable to use aluminium strip it is wide having a size of 8mm to 16mm,
0.2mm to 1mm is thick.
