Rapid electric arc fused deposition and laser shock forging combined part forming method and device

Abstract

The invention discloses a rapid electric arc fused deposition and laser shock forging combined part forming method. The rapid electric arc fused deposition and laser shock forging combined part forming method comprises the steps that firstly, a pre-formed part model is divided into one or several simple forming units through a simulation system, and the forming sequence of the forming units is determined; secondly, numerical control equipment controls an electric arc welding gun to carry out fused deposition forming layer by layer on a machined material on a machining base plate of a moving platform, and a cladding layer is formed; and thirdly, a computer controls the moving platform to move, a fusion region keeps a horizontal state all the time, and meanwhile a computer controls pulse laser beams to carry out synchronous shock forging on the electric arc fused deposition metal region at the plastic deformation temperature. The invention further provides a rapid electric arc fused deposition and laser shock forging combined part forming device. The rapid electric arc fused deposition and laser shock forging combined part forming method and device have the beneficial effects that a formed structure is good in structure stability, the yield is high and safety and reliability are achieved.
