Trans. Nonferrous Met. Soc. China 25(2015) 2516-2523 Porosity sensitivity of A356 Al alloy during fiber laser welding Kai LI1,2, Feng-gui LU1,2, Song-tao GUO1, Hai-chao CUI1,2, Xin-hua TANG1,2 1... power is 5 kW and defocusing value is 0. Key words: A356 Al alloy; fiber laser welding; porosity; keyhole; plume 1 Introduction As one of the most advanced technologies, laser welding has gotten a huge......
. As for the A356 alloy, the critical fracture stress is about 0.1 MPa. The hot tearing surface morphology shows that the remaining intergranular bridge and liquid films are thick enough to allow the formation of dendrite-tip bumps on the fracture surface. Key words: hot tearing; tensile force; A356 alloy; aluminum alloy; liquid film; solid fraction 1 Introduction The cast Al-Si alloys are widely used......
