Fusion interface stress and its potential effect on microcrack in 10-kW level laser welding
Source abstract
Abstract
Fusion interface stress is sharply produced by heating–cooling cycle in 10-kW level laser welding of stainless steel 316L with 10 mm thick, and it has a direct contribution to microcrack formation. This topics is investigated through proposing a macro–microcoupling model that consists of four submodels: ① hybrid double ellipsoidal and peak linearly-increased Gaussian cylinder heat source are combined to simulate thermal cycle and distribution; ② 3-D Voronoi tessellation is applied to establish the weld grain (average size 60 μm) structure; ③ solidification procedure is developed based on temperature-related solid-phase fraction to obtain shrinkage displacements of weld pool and fusion interface; ④ elastic–plastic mechanical analysis constitutive submodel is used to analyze transient stress on fusion surface and its potential effect on microcrack. Experimental microstructure is obtained to investigate solidification cracking. Relative error of weld size is 2.9% between experiment and simulation results. The shrinkage displacement is 5.5 μm along the parallel direction of weld section when tensile stress reaches 291.7 MPa, and microcrack occurs in the solidification weld. The solidification cracking of 316L 10 kW-level laser welding can be predicted based on the obtained peak value of tensile stress on fusion surface.
