美刊《焊接设计与制作》1984年第2期报导,根据IIW第ⅡA分委会的计划,瑞士的焊接工作者研究了焊接材料的烘干温度与焊缝中氢含量的关系。 他们发现:将手工涂药焊条在450℃(840°F)下烘焙1小时,水份可大为降低;同时发现,某些粘结剂的组成可减少焊条在保管过程中吸收水份。由 According to the IIW Subcommittee IIA’s plan, welding workers in Switzerland studied the relationship between the drying temperature of the welding material and the hydrogen content in the weld. They found that the hand-coated electrodes were baked at 450 ° C (840 ° F) for 1 hour and their moisture content was greatly reduced. At the same time, it was found that the composition of some binders reduced the moisture absorption of electrodes during storage. by
