焊剂使用的注意事项

焊剂使用的注意事项Fluxusingthemattersneedingattention（1）焊剂应放在干燥的库房内。库房内应装有去湿机，控制室内湿度，防止焊剂受潮，影响焊接质量。(1)fluxshouldbekeptindryinsidestoreroom.WarehouseshouldbeequippedwithQuShiJi,controltheindoorhumidity,preventfluxbeaffectedwithdampbeaffectedwithdamp,affecttheweldingquality.（2）焊剂使用前应按说明书所规定的参数进行烘焙，通常在250至300摄氏度：烘焙2小时。(2)thefluxshouldbeaccordingtotheinstructionmanualbeforeusingtheparametersspecifiedinbaking,usuallyfrom250to250degreesCelsius,bakefor2hours.（3）为防止产生气孔，焊前接缝处及其附近20毫米的焊件表面应清除铁锈、油污、水分等杂质。(3)topreventblowholes,beforeweldingseamsonthesurfaceoftheweldanditsnear20mmshouldremoverust,oil,waterandotherimpurities.（4）回收的焊剂，应过筛清除渣壳、碎粉及其他杂物，与新焊剂按比例混合均匀后使用。(4)therecyclingflux,sievingshouldbeclear,crushedslagshellpowderandothergroceries,andthenewfluxproportionalmixingafteruse.（5）埋弧焊的焊剂必须与所焊钢种和焊丝相匹配，保证焊接质量和焊缝性能。电渣焊的焊剂应具有适当的导电率；适当的黏度；较髙的蒸发温度；良好的脱渣性、抗裂性和抗气孔的能力。(5)ofthesubmergedarcweldingfluxmustmatchtheweldingsteelandweldingwire,ensurethequalityofweldingandweldingperformance.Electroslagweldingfluxshouldhaveappropriateconductivity;Theproperviscosity;Ahighevaporationtemperature.Goodtotakeofftheslagresistance,crackresistanceandstomatalresistanceability.
