| 摘 要： | 本文介绍了采用普通４．０Ｈ０８Ａ焊芯，通过调整焊条药皮、造渣涂料、合金系统及其元素的含量，尤其是通过加入微量的焊缝金属韧化元素，在保证焊缝金属强度的条件下来改善和提高焊缝金属的韧性，试验结果证明：当焊条药皮渣系为大理石－萤石－石英－钛白粉，其百分比含量为４．８：３．４：１：１时，焊条的工艺性能最好；当ＮＱ６０－ＨＱ１００异种低合金钢焊条的合金系统为Ｍｎ－Ｍｏ－Ｎｉ和Ｍｎ－Ｍｏ－Ｃｒ时，焊缝金属的机械性能均能满足母材的要求．从而为ＨＱ６０－ＨＱ１００低合金高强度调质钢的焊接提供了新的高韧性焊接材料。

| Abstract: | This article outlines that the toughness of weld is improved by using common core wire of H08A,4.0mm in diameter and adjusting coating of an elecetode,slag forming coatings,allo-ying systems and the content of alloying elements while its strength is not changed. The testproves that when CaCO_3:CaF_2:SiO_2:TiO_2 in coating is 4.8:3.4:1:1 the technology of this electrodeis the beast. When the alloying systems of HQ6O -HQ100 low alloy steel electrod areMn-Mo-Ni and Mn-Mo-Cr mechanical properties of weld metal entirely are satisfactoryto requirment of parenet metal.There fore this piovides welding of HQ60-HQ100 low alloysteel with new high toughness welding material. |
