目前国内外关于单一活性剂在试验前设计的研究报道缺乏,为避免研究出现随机性和盲目性弊端,文中详细阐述了AZ31B单一活性剂的设计过程,研究了A-TIG电弧形态、焊缝熔深和焊缝表面成形质量。研究表明:通过对比分析文献信息,选定活性剂的基本元素和主要元素并对它们进行选配,最终确定欲研究的活性剂。这一设计思路是可行的。活性剂通过影响电弧形态收缩可致焊缝熔深增加,焊缝表面成形质量随活性剂与丙酮量的配比不同发生变化,9种活性剂在最大焊缝熔深时的丙酮量不同。综合分析认为,单质Zn为AZ31B镁合金A-TIG的首选活性剂。
At present, at home and abroad, there is a lack of reports on the design of single active agent before the experiment. In order to avoid the randomness and blindness of the study, the design process of AZ31B single active agent is described in detail. The effects of A-TIG arc morphology, Deep and weld surface forming quality. The research shows that by comparing the literature information, selecting the basic elements and the main elements of the active agent and selecting them, the final determination of the active agent to be studied. This design idea is feasible. The active agent can increase the penetration depth of the weld by affecting the shrinkage of the arc shape. The quality of the weld surface changes with the ratio of the active agent to the acetone content. The amount of acetone of the nine active agents at the maximum weld penetration is different. Comprehensive analysis shows that Zn is the preferred active agent for AZ31B magnesium alloy A-TIG.
