Abstract
A method comprises fusion welding a filler metal to a first aluminum component; wherein the first aluminum component comprises a 7xxx series aluminum alloy; and wherein the filler metal comprises an aluminum alloy, in weight percent: up to 0.15 Fe; up to 0.15 Si; from 2.3 to 2.7 Mg; from 1.4 to 1.8 Cu; from 6.0 to 9.0 Zn; and from 0.06 to 0.14 Zr. In some embodiments, the 7xxx series aluminum alloy comprises 0.5-2.6 wt. % Cu. In some embodiments, the filler metal comprises, in weight percent, up to 0.45 Sc.
Claims21
A method comprising:
- a. fusion welding a filler metal to a first aluminum component;
- i. wherein the first aluminum component comprises a 7xxx series aluminum alloy;
- ii. wherein the filler metal comprises an aluminum alloy, in weight percent:
- 1. up to 0.15 Fe;
- 2. up to 0.15 Si;
- 3. from 2.3 to 2.7 Mg;
- 4. from 1.4 to 1.8 Cu;
- 5. from 6.0 to 9.0 Zn;
- and
- 6. from 0.06 to 0.14 Zr.
A method comprising:
- a. abutting a first aluminum component against a second aluminum component, wherein an abutment is formed, and
- b. fusion welding a filler metal to the first aluminum component and to the second aluminum component so that a welded joint is formed at the abutment;
- i. wherein the first aluminum component comprises a 7xxx series alloy;
- ii. wherein the filler metal is an aluminum alloy comprising, in weight percent:
- 1. up to 0.15 Fe;
- 2. up to 0.15 Si;
- 3. from 2.3 to 2.7 Mg;
- 4. from 1.4 to 1.8 Cu;
- 5. from 6.0 to 9.0 Zn;
- and
- 6. from 0.06 to 0.14 Zr.
A method comprising:
- a. locating a surface defect of a mold block;
- i. wherein the surface defect has a first volume;
- ii. wherein the surface defect is at least partially surrounded by an original volume;
- iii. wherein the mold block includes the original volume;
- iv. wherein the mold block is made of an aluminum alloy;
- and
- b. wherein the aluminum alloy is a lox series aluminum alloy;
- c. repairing the surface defect, wherein the repairing comprises fusion welding a filler metal to at least a portion of the original volume to produce a repaired volume;
- i. wherein the repaired volume includes the first volume of the surface defect and at least a portion of the original volume;
- and
- ii. wherein the filler metal is an aluminum alloy comprising, in weight percent:
- 1. up to 0.15 Fe;
- 2. up to 0.15 Si;
- 3. from 2.3 to 2.7 Mg;
- 4. from 1.4 to 1.8 Cu;
- 5. from 6.0 to 9.0 Zn;
- and
- 6. from 0.06 to 0.14 Zr.
