增材制造技术是一项革命性的制造技术,它颠覆了传统的减材制造方式,尤其金属增材制造,作为一项革命性、先进性制造技术,广泛应用于航空航天、生物医疗、工业模具和动力能源等相关领域。目前金属增材技术主要分为激光增材和电弧增材,其中,激光增材具有成型效果好,精度高等优点,但其制造的工件尺寸较小,成型速度较慢,所以目前只用来制造比较精密的工件;电弧增材制造技术是通过电弧熔化丝材,并根据产品三维模型将熔融金属按线-面-体逐层堆积、凝固成形出金属部件的工艺。电弧增材制造技术可实现大尺寸的工件制造,并且其制造速度远超过激光增材,然而应用于电弧增材工艺的制造设备精度较低,制件表面粗糙度较大,制造过程热输入大,产品加工应力较大,易产生裂纹等。

需要说明的是,许多产品都需要焊枪进行往返运动以满足其所需的高度,因此整个工件150位于第三超声换能器生成的超声场内,但对于有多个第三超声波换能器132的情况,可以仅开启当前工件150熔化处所对应的第三超声波换能器132。
需要说明的是,底部超声装置130通过底部超声波发生器131驱动第三超声波换能器132工作,使得第三超声波换能器132发射超声波以对工件150进行超声冲击,超声的冲击作用会对熔池起搅拌作用,从而排除熔池中的气泡,同时会破碎熔池凝固过程中颗粒较大的晶粒,不断细化焊缝晶粒,使焊缝力学性能得到提高,增强工件150的质量。相对单一的旁路超声装置120,底部超声装置130对熔池的搅拌作用增强,更加易于排除熔池中的气泡、破碎熔池凝固过程中颗粒较大的晶粒,进一步增强了工件150的质量。
