Claims
- 1. A method for constructing welded construction, comprising the steps of:(a) providing separate component parts of the construction; and (b) welding the separate parts together with an aluminium-base weld filler alloy in the form of a weld wire, wherein each of the separate component parts welded together with the aluminium-base weld filler alloy and the weld wire respectively have the following composition in weight percent: Mg5.0-6.0Mn0.7-1.2Zn0.4-0.9Zr0.05-0.3Cr0.15 max.Ti0.2 max.Fe0.5 max.Si0.5 max.Cu0.25 max.balance aluminium and inevitable impurities.
- 2. A method according to claim 1 wherein the component parts of the construction are provided in the form of an extrusion, plate, sheet or a combination thereof.
- 3. A method according to claim, wherein the alloy has an Mg/Zn-ratio larger than 5.
- 4. A method according to claim 1, wherein the Ti content is 0.05-0.1%.
- 5. A method according to claim 1, wherein the Fe content is 0.10-0.30%.
- 6. A method according to claim 1, wherein the Si content is 0.10-0.30%.
- 7. A method according to claim 1, wherein the Cu content is 0.05% max.
- 8. A method according to claim 7, wherein each impurity is present at 0.05% maximum and the total of impurities is 0.15% maximum.
- 9. A method according to claim 8, wherein each of the separate component parts welded together with the aluminium-base weld filler alloy and the weld wire respectively has a beryllium content of at most about 0.00008%.
- 10. A method according to claim 1, wherein the Zn content is 0.5 to 0.9 wt. %.
- 11. A method according to claim 10, wherein the Zr content is 0.12 to 0.3 wt. %.
- 12. A method for constructing welded construction, comprising the steps of:(a) providing separate component parts of the construction; and (b) welding the separate parts together with an aluminium-base weld filler alloy in the form of a weld wire, wherein each of the separate component parts welded together with the aluminium-base weld filler alloy and the weld wire respectively consist of, in weight percent: Mg5.0-6.0Mn0.7-1.2Zn0.4-0.9Zr0.05-0.3Cr0.15 max.Ti0.2 max.Fe0.5 max.Si0.5 max.Cu0.25 max.balance aluminium and inevitable impurities.
- 13. A welded structure comprisingcomponents welded together with an aluminium-base weld filler alloy from a weld filler wire, wherein the components and the weld filler wire comprise, in weight percent: Mg5.0-6.0Mn0.7-1.2Zn0.4-0.9Zr0.05-0.3Cr0.15 max.Ti0.2 max.Fe0.5 max.Si0.5 max.Cu0.25 max.balance aluminium and inevitable impurities.
