| 摘 要： | 从焊接效率与节能、微观组织、力学性能、断口形貌等方面对钛钙型双电极焊条(TE4303)单弧焊进行了研究.结果表明,与传统单芯焊条(E4303)电弧焊相比,当采用相同的焊接电流时,TE4303单弧焊熔化系数和熔敷系数可提高1倍,熔化单位重量焊条金属节省电能约20%～30%;TE4303单弧焊对母材热输入小,接头熔合比小,...

| Abstract: | Single arc welding with twin electrode(TE4303) was studied from the welding efficiency and energy saving,microstructure,mechanical properties,and fracture morphology.The results show that melting coefficient and deposition coefficient of TE4303 single arc welding are as two times higher as that of the traditional single electrode(E4303) arc welding.Compared with E4303 arc welding,TE4303 single arc welding can save electrical energy about 20%~30% to melt per unit weight of electrode metal.Meanwhile,its welding heat input is low to get the small fusion ratio.The columnar grains in weld are much slimmer at the same welding current.It is also found that both the compositions and mechanical properties of the deposited metal meet the requirements of standards.The analysis on fracture appearance shows that it is ductile fracture with dimple mode,and the inclusions are oxides which are analyzed by electron probe microscope. |
