关于焊接Lifting rings标准,科索比为用户所提供的的焊接Lifting rings的标准是: 80级焊接D-ring采用高强度高韧性合金钢锻造而成,经过调质热处理。按照工作拉力的2.5倍进行静载验证测试,抽检以载额的1.5倍进行20000次疲劳验证测试,每一批产品进行严格的抽样破断测试以及磁粉探伤。因此在质量上用河以放心使用。
对于焊接Lifting rings标准,焊接底座内置定位弹簧,此作用是为了方便控制D-ring的多个角度,科索比专业生产焊接D-ring,本公司推荐使用焊条为低碳钢焊条,额定载荷20T、30T、 50T的都有。在焊接前,接触表面需保持清洁无铁屑、油污、油漆、炉渣或其它污染物。表面如已腐蚀,焊接表面需将铁屑去除,若有油漆也需去除。焊接母材含碳量 要低于0.40%。,室温低于10°C时,焊接之前表面需要做预热处理。焊接点须具备足以载重之荷重需求。焊接之前,用户需要清理焊道避免夹渣。
焊接作业一旦开始请勿中断,避免元件冷却,还有温度影响,焊接结构可以进行退火处理,温度<600*C,进行应力释放,并且不会降低工作质量,请勿快速冷却焊接点。请对焊接 点进行全面检查,不得出现有裂缝、凹陷或刻痕。如果要修补的话,那就将瑕疵研磨干净,再次进行合格焊接操作。
