Welding needs to be calm

welders nowadays will receive corresponding training before taking up their posts, but the freshness and impetus of young welders when they pick up the welding gun can cause accidents if they are not careful. Therefore, in the enlightenment stage, the most important thing is to be patient and calm, and put safety and regulations first.

The obsession stage, to put it bluntly, is addiction. A person who is passionate about work should have an obsession with his or her professional field. Love to think, love to learn, and love to ask are the most obvious characteristics of my stage. At this stage, I bought some professional books, hoping to understand the mysteries of welding operations in the books. Unfortunately, the society was in the afterglow of the Cultural Revolution at that time, and there were few professional books on welding, unlike now when there are so many professional books for everyone to choose from. In addition to reading books, I also learn more from experienced welders around me.

For example, the accident I mentioned just now was mainly because I failed to distinguish between molten iron and slag at that time. Later, I finally figured out through learning that slag and molten iron are different in various positions and under different circumstances. Generally, single-layer flat welding has no groove. When the temperature of the molten pool is high and the molten pool area is large, the slag will float on the edge of the molten pool, appearing dark brown and bubbling; the molten iron is shiny and looks like water. Multi-layer flat welding is different. The situation of the first and second layers of welding has changed. At this time, the slag and molten iron are hugged into a ball, and the slag appears in the center of the molten pool. How to separate the slag and molten iron? In fact, it is not difficult. When the temperature of the molten pool rises, the slag can be separated from it, but how to adjust the appropriate temperature? Some readers should think the same as I did at the beginning, try it first! Haha, in fact, there is a lot of knowledge here. It can be said that the adjustment of current is obviously different between observing others' adjustment and operating it yourself.
