众所周知,用于电弧焊的焊条对大气中的潮气十分敏感。焊条受潮将对其操作性能和焊接性能有严重的影响。因此各焊条制造厂家对焊条的包装都着实下了功夫,力图避免在运输途中被撞伤或受潮,确保无论在何时何地施焊都能获得优良的焊接质量。然而用户购入即使是用可靠防潮包装的焊条在保管期间或焊接现场仍难免会吸潮。如果焊条严重受潮,其工艺性能和焊接质量均将明显下降。而如果把已受潮的焊条再烘干,又可能在药皮处产生干燥裂纹。所以最好还是把焊条保存在干燥的地方,以尽量避免受潮为好。但是,实际上焊条在保存中多少都会吸潮。所以不管怎样仍有必要再烘干,但是若 It is well-known that electrodes for arc welding are very sensitive to the moisture in the atmosphere. Moisture of the electrode will have a serious impact on its operating performance and welding performance. As a result, each electrode manufacturer has taken a real-time look at electrode packaging in an attempt to avoid being bruised or damp during transit, ensuring excellent welding quality no matter when and where it is applied. However, even if the user purchased the electrode with reliable moisture-proof packaging is still inevitable moisture absorption during storage or welding site. If the electrode is seriously damp, its process performance and welding quality will be significantly reduced. And if the electrode has damp and then drying, but also may produce dry crack in the skin. So it is best to keep the electrode in a dry place to avoid damp as well. However, in fact, how much the electrode will absorb moisture in the preservation. So it is still necessary to dry again anyway, but if
