Default |清大圣科坚决反骗子.|焊条在各种环境下的保管

焊条的保管:
各类焊条必须分类、分牌号存放,避免混乱,同时应存放在干燥、通风良好的仓库内,并要放置在离地面及墙壁不 少于300mm处,以防受潮变质。××清大圣科×清大圣科电焊条&t imes;清大圣科电焊条设备×清大金桥×清大金桥电焊条设备×清大 圣科气化炉×www.qhsk.cn×清大圣科科技有限公司×&ti mes;
由于药皮容易受潮,受潮后的焊条工艺性能变坏,而且水分中的氢容易使焊缝产生气孔和裂纹,故焊条使用前必须 烘干,以降低焊条的含氢量,一般采用350~450o,保温1~2小时,烘干。×&times ;清大圣科×清大圣科电焊条×清大圣科电焊条设备×清大金桥&tim es;清大金桥电焊条设备×清大圣科气化炉×www.qhsk.cn&times ;清大圣科科技有限公司××
