新型低能量焊接工艺参数对熔敷速度的影响
摘要
新型低能量焊接技术(New Low Energy Welding Technology,简称NLE)是一种新型焊接方法,采用推拉送丝方式完成熔滴过渡,焊接过程无飞溅并能有效降低焊接热输入。NLE焊接系统通过电流输出和焊丝运动相互匹配,两者协同工作实现稳定焊接。通过焊接工艺试验深入研究燃弧峰值电流I,1,、保持时间T,1,、送丝速度v,1,、焊丝送进延时时间T,4,、焊丝回抽速度v,2,及焊丝回抽延时时间T,5,等控制参数对焊丝熔敷速度的影响规律。结果表明:随着I,1,、T,1,、v,1,、v,2,和T,5,的增大,焊丝熔敷速度增大,并且I,1,和T,1,对焊丝熔敷速度的影响较显著,而v2和T,5,对焊丝熔敷速度的影响不明显,随着T,4,的增大,焊丝熔敷速度逐渐减小,适当调节焊接控制参数可以有效控制焊丝熔敷速度。
Abstract
The new low energy welding technology is a new welding method and completes metal transfer by push-pull wire feed,there is no spatter during the welding process,and the heat input is reduced effectively. The current output and the wire movement match each other to achieve a stable welding. Through the welding procedure test,the influence of control parameters(such as arc peak current I,1,hold time T,1,wire feed rate v,1,the delay time of wire feed T,4,wire withdrawal rate v,2, and the delay time of wire withdrawal T,5,etc.)on the deposition rate of wire is studied. The results show that as the I,1,T,1,v,1,v,2, and T,5,increase the deposition rate of wire improves,and the effect of I,1, and T,1,on the deposition rate is outstanding,but the effect of v,2, and T,5, is not obvious,and with the increase of T,4,the deposition rate decreases,so that the deposition rate of wire can be controlled effectively by adjusting the welding parameters appropriately.
