摘要

铝合金电弧增材制造过程稳定性不足，精度较低，容易产生各种缺陷。为优化铝合金增材制造工艺，研究了丝材感应预热工艺对铝合金电弧增材制造的优化作用与效果，以TIG电焊机为热源，采用ER4043焊丝在纯铝基板上增材制造薄壁构件，探索感应预热焊丝工艺参数对成形件微观组织与硬度的影响。经过单道试验和增材制造薄壁试样，得出热丝工艺的堆积效率相较于冷丝工艺增加了11.1%，成形形貌更加均匀，气孔数量大幅减小，硬度增加了25%~35%。感应预热焊丝工艺对铝合金增材制造技术的优化效果显著。

Abstract

Aluminum alloy arc additive manufacturing technology is a kind of advanced manufacturing technology which has the characteristics of fast net proximity forming. Due to the lack of stability

low precision and easy to produce various defects in aluminum alloy arc additive manufacturing process

this technology needs to be optimized. To optimize the additive manufacturing process of aluminum alloy

the optimization effect of the wire induction preheating process is studied

using TIG welding machine as heat source

thin wall components were fabricated by adding ER4043 welding wire on pure aluminum substrate

the process parameters of induction preheating welding wire were explored

the microstructure analysis and test of the forming parts were conducted.Through single-pass test and additive manufacturing of thin-wall samples

it is concluded that the accumulation efficiency of hot wire process is greater than that of cold wire process

the shape morphology is better than that of cold wire process

the number of pores in the formed parts is greatly reduced

the hardness is significantly increased

and the optimization effect of induction preheating welding wire process on the additive manufacturing technology of aluminum alloy is remarkable.
