The precision aluminum tube has better performance. The manufacturer will weld the aluminum tube. When welding, we need to pay attention to some matters:
1. The successful one-time welding effect is better. Because the aluminum tube melting and cutting tool point is too low, the aluminum tube is very simple to deform when the second time is reheated.
2. It is necessary to evenly apply flux to the electrode to ensure the quality of the solder joint.
3, the torch flame can not be too long, and it is necessary to use a micro-fire to heat, otherwise the dispersant aluminum tube is very simple to melt.
4, the end of the welding, to wait for the special nylon nylon slurry for two or three minutes after the tube is cooled, the cement storage can touch, otherwise the solder joints are easy to leak.
5, the welding time can not be too long, because the melting point is too low, too long, the aluminum tube wall is ablated or thinned, the pressure is very simple to leak.
6, the liner is necessary to put wet towels, maintenance in place, because the welding space is very small, so must pay attention to the maintenance of the refrigerator
7. The welding rod cannot be heated by the welding torch and then the welding powder is taken. The melting point of the electrode is too low.
