Heat source model of lap laser welding of stainless steel vehicle

  Resistance spot welding (RSW) is being taken place by partial lap laser welding for the poor surface quality and bad airtight due to the pressure of electrodes.The shape of partial lap laser welding is similar to the vase.When the penetration of the joint is in a certain range,there is no welding trace on the outer surface.Laser welding temperature field numerical analysis based on Abaqus finite element analysis software is committed to obtain a suitable range of process parameters to improve production efficiency and automation by determining the joint penetration.To master the laser lap welding of stainless steel weld penetration state,the combination of three-dimensional positive cone + three-dimensional inverted cone + half-ellipsoid heat source model was established simulating stainless steel lap laser weld pool shape and forecasting the range of process parameters.
