An Oil-water Model for Slag Entrainment in Melting Bath of Vacuum Refining Unit with Single-snorkel 单嘴精炼装置真空室内卷渣水模型研究
One is raising wire molten rates, which means melting more wire per unit time, the most common method of which is to increase welding current. 其一,提高焊丝熔化速度,即单位时间内熔化更多的焊丝,增大焊接电流是最为普遍的做法;其二,提高熔敷效率。
In MPS multi-electrode system, two or more welding arcs burning in one molten pool, the heat input is several times of single power supply. It greatly incases the welding productive because the amount of melting metal in a unit time is increased. 多电源多丝焊接工艺中几个焊丝在一个熔池内燃烧,总的热量输入是单丝焊接热量输入的若干倍,使单位时间内金属的熔化量大大提高,从而可以明显提高焊接生产率。
