Aluminum welding operations required

1 welding torch can not be dipped in solder powder after heating, because the low melting point rod.

2 welding time success better, because aluminum alloys melting point is too low peeling knives, the second reheating tubes easily deformed.

3 liner must be placed wet towels to protect the place, because the welding space is very small, so be sure to pay attention to the protection of the refrigerator.

4 torch flame is not too long, and must be heated with a slow fire, or dispersing agents tubes easily melted.

5 welding is completed, the slurry to wait two special nylon yarn, three minutes after the cement pipe cooling can access the repository, or leaky joints.

6 Welding flux must be applied evenly to ensure the quality of solder joints.

7. Welding time not too long, because the melting point is too low for too long aluminum tube wall easily lead to melting or thinning, suppressed easily leak.

8 welding torch can not be dipped in solder powder after heating, because the low melting point rod.
