摘要:
提出一种激光焊接温度场的解析计算方法 .将激光作用下形成的小孔区域作为均匀吸收介质,导出介质热源的功率分布三维解析式,以及由该热源引起的无限大薄板的温度场分布解析式 .计算和实验验证该解析式的正确性,理论计算和实验结果符合较好 .当小孔深度为零时,介质热源即为表面热源,所得到的解析式与其它热传导焊理论解析式一致
Abstract:
An analytic method is proposed for calculating temperature field of laser welding.Taking orifice zone formed under laser action as evenly absorbing medium,the author derives a 3D analysis formula to power distribution of heat source in medium; and also an analysis formula to temperature field distribution over infinitely great sheet induced by this heat source. These solutions are verified by calculation and experiment to be correct. Theoretical calculation and experimental results are well coincided. In case the depth of orifice equals to zero,heat source in medium is just the heat source on surface,the analysis formulae so obtained are consistent with other theoretical ones of heat conducting welding.
