【摘要】 针对低碳钢研制了由卤化物，ＳｉＯ２ 和 Ｃｒ２Ｏ３等组成的高效 ＴＩＧ 焊活性剂，分析了各单一活性剂对焊接熔深的影响规律，并利用正交试验法对多组元配方进行了研究，得出了各组元的质量分数变化对焊接溶深的影响规律．所得到的配方可使焊接溶深增加３倍，并可以将１２ ｍｍ厚的低碳钢钢板对接一次焊透。更多还原

【Abstract】 An efficient activating flux made of Sio2,TiO2,Cr2O3 , halogenide, etc for TIG welding of low carbon steel is developed. The influence pattern of each individual component of the activating flux on the weld penetration is analyzed first. Then, by using crosscutting method, multicomponent compounding is investigated. Thus the influence pattern of the mass fractions of idividual components on the welding pene- tration is obtained finally, so that the optimal compounding can made the penetration deepened by triple, abling to weld through low-carbon steel plate in thickness of 12 mm once and away更多还原
