Seamless aluminum tube is widely used in daily life, welding, cutting and other processing techniques are often used. Today, we summarize some welding matters of seamless aluminum tube:
1. The liner must be placed wet towel, protection in place, because the welding space is very small, so be sure to pay attention to the protection of the refrigerator.
2. The welding rod cannot be heated with the welding gun before dipping into the welding powder, because the melting point of the electrode is too low.
3. The one-time successful welding effect is better. Because the melting cutting tool point of aluminum tube is too low, the aluminum tube is easy to deform when it is reheated for the second time.
4. After welding, the cement storage can be contacted after the special slurry of nylon wire is cooled for two or three minutes, otherwise the solder joint is easy to leak.
5.The torch flame can not be too long, and must be heated with small fire, otherwise the dispersant aluminum tube is easy to melt.
6. The welding time can not be too long, because the melting point is too low and the time is too long, it is easy to melt or thin the aluminum tube wall, and it is easy to leak under pressure.
7. The welding rod of seamless aluminum tube cannot be heated with the welding gun before dipping in welding powder, because the melting point of the electrode is too low.
8. The electrode must be evenly coated with flux to ensure the quality of the solder joint.
