Under the actuality of our country and according to the development and application of flux-cored wire, we have some personal opinions about the research, that is, we use pure CO2 as shielded gas and basic slag system as direction for metallurgical products to do the research on flux-cored wire.
针对药芯焊丝的发展及应用概况,结合我国现状提出了以100%CO2为保护气体,以碱性渣系为配方的药芯焊丝的看法。
were applied to observe the droplet transfer and arc properties of the gas shielded flux cored wire of basic slag system, and the paper studied the shaping mechanism and influencing factors of the vertical-up welding.
采用平板对接立向上焊接、焊接电弧物理观察等试验方法 ,观察了碱性渣系气体保护药芯焊丝熔滴过渡和电弧特性 ,研究了立向上焊焊缝成形机理及影响因素。
