Benelux Laser Event - 26/04/05-27/04/05 Benelux Laser Event - 26/04/05-27/04/05 Hybrid laser welding of 5xxx series aluminium alloys (2) * Overview Project ALUWELD Aluminium alloys (5xxx series) Experimental results Further research projects Conclusions * Project ALUWELD Innovative welding of high strength aluminium alloys with the Friction Stir Welding (FSW) en Hybrid Laser Welding (HLW) techniques 50% of fundings by IWT-Vlaanderen (IWT 30909) Duration: 2004-2005 Both welding processes have in common: low loss in strength low deformation fully automatic Aims: Building up base knowledge about both FSW and HLW Demonstrating the capabilities of FSW and HLW on relevant aluminium alloys for the industrial project members FSW: 2024-T3, 5754-O, 5182-H111, 5083-H111, 6056-T4, 6061-T6, 7475, AC-46000 HLW: 5083-H111, 5754-O, 5182-H111, 6056-T4, 6061-T6, 6082-T6, AC-46000 Modelling Comparison with ??traditional?? welding processes * Aluminium alloys: subdivision 1xxx: Al with different degrees of purity ( 99%) 2xxx: Al-Cu(Mg) 3xxx: Al-Mn 4xxx: Al-Si 5xxx: Al-Mg 6xxx: Al-MgSi 7xxx: Al-ZnMg(Cu) 8xxx: ??specialty alloys?? (e.g. Al-Sn) Aluminium wrought alloys (rolled products/extrusions): ??series?? based on chemical composition Depending on the chemical composition: * Al 5xxx series: properties Al-Mg alloys Non-precipitation hardenable Strength increase by cold deformation only Important influence of Mg on strength Very good corrosion resistance (but ICC/SCC possible) Good weldable Typical applications of 5xxx series: Welded structures, storage tanks, structural sheet… 5xxx Al-alloys within the project: 5083, 5754 and 5182 5754 5182 5083 * 5xxx Al-legeringen within the project Supplied by industrial project members: 5083-H111 sheets Al Mg4,5Mn0,7 (5-8 mm) Cryogenic applications, structural applications, piping and tubing… 5754-O sheets Al Mg3 (4 mm) Nuclear, chemical and food industry, load floors, pressure vessels… 5182-H111 sheets Al Mg4,5Mn0,4 (1,5
