Abstract

The invention discloses a method for controlling the vertical lapping morphology of a single-pass cladding layer manufactured by arc additive manufacturing. First, the first cladding layer is formed on a forming substrate, and the width and height of the first cladding layer are measured to determine Parabolic fitting parameters, determine the optimal layer height according to the fitting parameters, and then carry out the forming of the second cladding layer under the premise of keeping the wettability of the cladding layer stable according to the fitting parameters, so as to realize the improvement of the first cladding layer The control of the overlapping morphology of the first layer to the second cladding layer; the second cladding layer is used as a new cladding layer, and then the overlapping morphology of the new cladding layer is controlled until the vertical overlapping is completed, realizing The control of the vertical lap morphology of the cladding layer is achieved. The present invention is a method for controlling the vertical lapped appearance of a single-pass cladding layer manufactured by arc additive manufacturing. Vertical lapping effect of cladding layer.

Description

technical field

[0001] The invention belongs to the technical field of additive manufacturing, and relates to a method for controlling the vertical lap joint morphology of a single cladding layer manufactured by arc additive manufacturing. Background technique

[0002] Wire Arc Additive Manufacture (WAAM) is a method of using the principle of layer-by-layer cladding, using the arc as the heat source, under the control of the digital program, through the feeding of the wire and the three-dimensional digital model by wire-surface- Advanced digital manufacturing technology that gradually forms metal parts. At present, arc additive technology still faces great challenges in improving the surface quality of formed parts and reducing roughness. Traditional research methods often improve the surface quality of formed parts by changing the forming process parameters (welding speed, wire feeding speed, welding current, welding voltage). The shape after solidification and the factor...
