焊接熔渣的熔点对焊接冶金具有重要意义,它与焊缝金属熔点间的关系对焊缝成形影响较大。为了探究熔渣熔点对此种焊条焊缝成形的影响规律,以药皮辅料中主要的造渣剂-大理石、萤石、菱苦土、金红石加入量为试验因子,设计出四因素三水平的正交试验,测得各配方焊接熔渣的熔点,并观察相应焊缝成形的情况,分析熔渣熔点差异对焊缝成形的影响,得出四种辅料的最佳配比和最合适的熔渣熔点范围。 The melting point of the welding slag is of great significance to the welding metallurgy. The relationship between the melting point of the welding slag and the melting point of the welding metal has a great influence on the weld forming. In order to explore the influence of slag melting point on the formation of such welding electrodes, taking the main slagging agents - marble, fluorite, rhombic soil, and rutile in the coating materials as the test factors, four factors and three levels Orthogonal test, measured the melting point of each recipe of welding slag, and observed the formation of the corresponding weld, analysis of molten slag difference on the impact of the formation of the weld, obtained the best ratio of four kinds of materials and the most appropriate melting Slag melting point range.
