ã€China Aluminum Industry Network】1. The welding success is better at one time. Because the melting point of the aluminum tube is too low, the aluminum tube is easily deformed when it is reheated for the second time.

2. The electrode must be evenly coated with flux to ensure the quality of the solder joint.
3, welding torch flame can not be too long, and must be heated with a micro-fire, or dispersant aluminum tube is easy to melt.
4, welding is completed, to wait for the special nylon filament slurry two or three minutes before the cement storage reservoir can contact, otherwise easy to leak solder joints.
5, the welding time can not be too long, because the melting point is too low for too long time easily lead to aluminum tube wall melting or thinning, pressure can easily leak.
6, 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.
7. The welding rod cannot be used to pick up the welding powder after heating, because the melting point of the welding rod is too low.
