An orthogonal experiment was performed for laser welding of 5 mm ZL114A and 6061 aluminum alloys, and the influences of welding parameters on the microstructure and mechanical properties of welded joint were investigated. It is shown that the influences of three parameters of laser welding power, defocus and welding speed are in a descending order. With laser welding power of 3 kW, welding speed of 16 mm/s and the defocus of -3 mm, the welded joint has an average tensile strength of 208.03 MPa and the elongation of 5.16%. Compared to ZL114A and 6061 aluminum alloy, the tensile strength is reduced to 64.14% and 65.60%, respectively, while the elongation is reduced to 41.38% and 33.70%, respectively. The welded joint presents a mixed mode of brittle and ductile fracture when failing under tensile.

针对厚5 mm的ZL114A铝合金和6061铝合金进行了激光焊接正交试验,研究了激光焊接参数对接头显微组织和力学性能的影响。结果显示,激光焊接参数对焊接接头强度影响程度大小顺序为:激光焊接功率>离焦量>焊接速度;当激光焊接功率3 kW、焊接速度16 mm/s、离焦量-3 mm时可获得较好焊接接头性能,接头平均抗拉强度为208.03 MPa,分别为ZL114A和6061铝合金抗拉强度的64.14%和65.60%;接头延伸率为5.16%,分别为ZL114A和6061铝合金延伸率的41.38%和33.70%;焊接接头拉伸断裂形式为脆-韧混合型断裂。

针对厚5 mm的ZL114A铝合金和6061铝合金进行了激光焊接正交试验,研究了激光焊接参数对接头显微组织和力学性能的影响。结果显示,激光焊接参数对焊接接头强度影响程度大小顺序为:激光焊接功率>离焦量>焊接速度;当激光焊接功率3 kW、焊接速度16 mm/s、离焦量-3 mm时可获得较好焊接接头性能,接头平均抗拉强度为208.03 MPa,分别为ZL114A和6061铝合金抗拉强度的64.14%和65.60%;接头延伸率为5.16%,分别为ZL114A和6061铝合金延伸率的41.38%和33.70%;焊接接头拉伸断裂形式为脆-韧混合型断裂。

An orthogonal experiment was performed for laser welding of 5 mm ZL114A and 6061 aluminum alloys, and the influences of welding parameters on the microstructure and mechanical properties of welded joint were investigated. It is shown that the influences of three parameters of laser welding power, defocus and welding speed are in a descending order. With laser welding power of 3 kW, welding speed of 16 mm/s and the defocus of -3 mm, the welded joint has an average tensile strength of 208.03 MPa and the elongation of 5.16%. Compared to ZL114A and 6061 aluminum alloy, the tensile strength is reduced to 64.14% and 65.60%, respectively, while the elongation is reduced to 41.38% and 33.70%, respectively. The welded joint presents a mixed mode of brittle and ductile fracture when failing under tensile.
