摘要

介绍和分析了单电源双丝系统(DeepenTwin)构成、焊接应用价值、焊接工艺试验以及实际焊接应用。单电源双丝焊接系统由焊接电源、双丝送丝机以及双丝焊枪组成

系统简单

便于操作

既可用于手工焊也可用于专机和机器人的自动焊接。单电源双丝焊接系统能够实现单双丝的自由切换

既能进行单丝的打底焊接也能进行双丝大电流高熔覆率的焊接

最高熔覆效率较单丝焊接可提升50%。由于两根焊丝形成了较宽的单一电弧

电弧热量分布更均匀

焊缝不易咬边

并且不存在电弧干扰的问题

焊接飞溅低成形好

可获得比单丝焊接质量更高的焊缝

是一种新型的高速高效焊接解决方案。

Abstract

The composition

welding application value

welding process test and practical welding application of a single power source twin-wire system（Deepen Twin） are introduced and analyzed. Deepen Twin is composed of welding power source

twin-wire feeder and twin-wire welding gun

which is simple and easy to be operated. Deepen Twin can be used for manual welding and automatic welding of the special machine and robot. And it can realize the free switch between single wire and twin wires

and can be used for backing welding with single wire and welding with twin wires

high current and high cladding rate

and the maximum cladding efficiency can be increased by 50%. The twin wires form a single wide arc

thus the arc heat distribution is more uniform

undercut is not easy to occur in weld

and there are low spatter

good weld forming and no arc interference

the quality of weld obtained by twin-wire welding is higher than that by single wire welding

which is a new high-speed and efficient welding solution.
