Definitions
- the present invention relates to an Al-Mg-Mn weld filler alloy which is used for welding AIMg alloy members or structures which are used to construct large structures such as storage containers and vessels for marine and land transportation. Further, the invention relates to a welded structure which is produced by welding AIMg alloy members together with the Al-Mg-Mn weld filler alloy, thereby producing constructions such as transportation vessels, tanks, silos, tanker lorries, pressure vessels, bridges or trucks. Furthermore, the invention relates to a method for constructing such a welded structure or construction.
- Al-Mg-Mn weld filler alloys are known for use in large welded constructions which consist preferably of plates or extrusion members selected from the group of aluminium alloys of the AA ⁇ xxx-series.
- One of the standard weld filler alloys is the AA5183 alloy having the nominal composition, in weight %: Mg 4.3 to 5.2, Mn 0.5 to 1.0, Zn 0.25 max., Cr 0.05 to 0.25, Ti 0.15 max., Fe 0.40 max., Si 0.40 max., Cu 0.10 max., the balance substantially aluminium and incidental elements and impurities.
- AA5183 weld filler wire provides a good balance of high strength, corrosion resistance, bendability and weldability.
- an increase in magnesium is usually accompanied by a decrease in corrosion resistance in this type of AIMg alloys.
- JP-A-05169290 or GB-A-2000806 disclose weld filler alloys containing up to 6.0 weight % Mg up to 6.0 weight % Zn and up to 2.5 weight % Mn. The latter is disclosed in connection with a copper content of 0.2 to 0.5 weight %.
- EP-1019217-B1 discloses an Al-Mg-Mn weld filler alloy comprising essentially the following composition (in weight %): Mg 5.0 to 6.5, Mn 0.4 to 1.2, Zn 0.4 to ⁇ 2.0, Zr 0.05 to 0.3, the balance essentially aluminium and incidental elements and impurities.
- the document discloses an improved strength compared with conventional AA5183 filler wire when welding a conventional AA5083 alloy plate under regular MIG welding conditions.
- the known weld filler alloy provides improved welded constructions with considerable improved corrosion resistance in the base material, the heat effected zone and the weld seam.
- the weld filler alloy according to the invention and wherein there is provided an Al-Mg-Mn weld filler alloy having a good corrosion resistance and improved strength levels, having the following composition (in weight %): Mg 6.0 to 9.5 Mn 0.9 to 2.0 Zn 0.2 to 0.9
- Si ⁇ 0.5 Ti ⁇ 0.3 the balance substantially aluminium and incidental elements and impurities, typically each ⁇ 0.05, total ⁇ 0.20.
- the invention has most successfully found that an increase in the magnesium content results in higher strength levels without a decreasing corrosion performance by selecting respective manganese levels and zinc levels.
- weld filler alloy according to the present invention welded aluminium joints have a higher strength than the standard AA5183 welds and welds as disclosed in EP-1019217-B1 , incorporated herein by reference in its entirety.
- Weld filler alloys in accordance with the present invention have been found to be very successful for welding aluminium structures of Al- Mg alloys to themselves or to other aluminium alloys. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
- the weld filler alloy is provided in a form selected from the group consisting of wire, rod, or stick, and in this form preferably having a diameter in the range of 0.5 to 6.0 mm.
- the present invention achieves its high strength levels by maintaining a good corrosion resistance throughout a good balance of an elevated magnesium content with adapted manganese and zinc contents.
- Magnesium is the primary strengthening element in the weld filler alloy. It has been found that it is possible to produce weld wires from the weld filler alloy having more than 6.0 wt.% and up to 9.5 wt.% wherein it is preferable to have an amount of Mg in a range of 7.0 to 9.5 wt.%, more preferably in the range of 7.5 to 8.5 wt.%. In another embodiment a Mg-content of 6.0 to 7.5 wt.% is preferred. By adjusting the manganese and zinc levels it was found that less cracking during casting and subsequent processing of the filler alloy could be achieved, while still providing a strength increase to the welded structures.
- Manganese is an essential additive element to the filler wire. Mn in combination with Mg provides the strength to the welded joins. Manganese is present in an amount of 0.9 to 2.0 wt.%, and preferably in a range of 0.9 to 1.8 wt.%. These elevated manganese levels correspond with elevated magnesium levels and lead to the improved strength levels of the weld filler alloy.
- Zn is an important additive for corrosion resistance of the weld seams, in particular when used for the welding of alloy products of the preferred composition defined above. It has been found that the amount of Zn is preferably in a range of 0.4-0.7 wt.%, preferably 0.45 to 0.7 wt.% when regular TIG-welding is applied, and a preferred range of 0.5 to 0.9 when regular MIG-welding is applied, in order to maintain a good weldability of the filler alloy and to provide a sufficient corrosion resistance.
- Zr is important to also achieve a strength improvement in the weld seams.
- Zr is important for resistance against cracking during welding and it has been found that a preferred range of Zr is in a range of 0.05 to 0.25 wt.% and more preferably 0.1 to 0.2 wt.%.
- Zr levels above 0.3 wt.% result in very coarse needle-shaped primary particles which cause unacceptable failures during wire drawing operation and therefore the Zr level should be kept below 0.3 wt.%.
- Scandium in the weld filler alloy can be present in an amount of up to 2.8 wt.% which has the advantage of grain refinement during casting or welding and an additional increase in strength from AI 3 Sc precipitates.
- the preferred range for the Sc in the filler wire is 0.25 to 2.8 wt.%.
- Ti is a known grain refiner element which may be present in a range of up to 0.3 wt.%, and a preferred range for Ti is 0.03 to 0.2 wt.%.
- Each of iron and silicon are regular elements in weld filler alloys, and their presence should not exceed 0.5 wt.%, and preferably each of their content is not more than 0.25%.
- the Cu content in the filler alloy should not exceed 0.5 wt.%, and preferably it should not exceed
- the more preferred Cu level is 0.10 wt.%, and most preferably the Cu is present at levels ⁇ 0.03 wt.%.
- each impurity should be present at 0.05 % maximum and the total of impurities is 0.20.
