voestalpine Böhler Welding

实芯焊丝

Wire Volume Systems for Cost-Efficient MIG/MAG Welding. Welding wires from Böhler Welding can be supplied in special volume packaging in the form of round and octagonal drums with filling contents from 250 up to 500 kg, depending on wire type and diameter. They provide efficient MIG/MAG welding, especially in mechanized and robotic operations where the elimination of time consuming wire spool exchanges yields drastically increased duty cycles and production output.

气体保护金属电弧焊接 (惰性气体保护焊/活性气体保护焊流程)

惰性气体保护焊/活性气体保护焊流程是气体保护机械焊接工艺,在气体保护下,以焊丝为电极,而电弧在有电流的焊丝及工件之间燃烧着。焊丝由卷盘机械输送,并在各自的电弧熔化。 

惰性气体保护焊接流程中,以氩、氦或这些气体的混合体为保护气体。活性气体保护焊流程中的保护气体一般由氩加氧气、氦加氧气、二氧化碳或这些气体的混合体组成。保护气体确保稳定电弧的形成,而且减少焊接熔池的表面张力并避免其与空气接触。 由此形成更为光滑的焊缝及焊缝边缘的良好过渡。此外,金属向电弧的转移也更加顺畅。

焊丝电极合金成分的烧除可通过过度的合金化进行弥补。焊接区域无通风是至关重要的。若焊接速度及摆动比较快,须注意保护气体的合适数量,此外,须选择合适的喷嘴的形状,以确保熔化焊接池的有效屏蔽。

一般以电极为正极,因此,只能将直流变换器或整流器用为电源。虽然用负极焊接可提升金属沉积效率,但熔滴过渡量更高,而且电弧的稳定性更低。根据电弧电压的强度,将焊接流程称作“喷射电弧”或“短弧”
