What should be done when the surface of the roller is strengthened and the sj301 flux is affected with moisture?
Sometimes because of storage problems, sj301 flux will be affected with moisture. When this happens, in order to avoid being at a loss, Xiaobian brings the following methods for you!
1、 Take out several welding rods from different directions, and use the thumb and index finger of both hands to support the welding rod quietly. If the welding rod is monotonous, it will produce a hard and brittle metal sound. If the welding rod is damp, it will be dull. In the use of electrode often do a variety of tests, monotonous and wet electrode between the movement is not the same, so as to prevent electrode moisture.
2、 If cracks and air holes are found when welding with some type of wetted electrode, it is necessary to consider whether the electrode is dry or not, and then consider other reasons.
3、 If the moisture content of the domestic wetted electrode is very high in sj301 flux factory, even water vapor can be seen on the surface of the electrode. Maybe when more than half of the wear-resistant electrode is welded, cracks appear at the end of the electrode.
