1, learn more, summarize more, practice more, improve welding technology level and improve hot metal control ability;
2. Reasonable selection of welding current and covered electrode.
3. Control the welding position reasonably, because flat welding is the easiest way to get beautiful weld.
4. Here is a brief talk about the flat welding technique, and pay attention to the study of the angle and amplitude of the bar; The narrow weld of thin plate can block the groove on both sides, and the swing is small. Keep the arc down and drag covered electrode away. When covered electrode falls off, the coating will fall off by itself when replacing covered electrode. Don't move it, so as not to pollute the joint when reigniting the arc. The covered electrode of the welded intermediate plate is S-shaped, which can produce fish scales. The covering electrode is 8-shaped, which can produce a double fish scale pattern. In a word, arc suppression is very important. The scales of Pisces welded by our colleagues are as beautiful as the flowers scraped by the fitter's scraper. In addition, when welding pipes, the molding inside is basically the same as that outside.
