Aluminum welding Notes:
1, welding time success better, because peeling knives aluminum melting point is too low, while the second reheating tubes easily deformed.
2, the electrode must be evenly flux, in order to ensure the quality of solder joints.
3, torch flame can not be too long, and must be heated with a slow fire, otherwise dispersant easily melted aluminum.
4, the welding is completed, nylon yarn special paste to wait two, three minutes after the cement pipe cooling can contact the repository, otherwise leaky joints.
5, welding time not too long, because the melting point of aluminum is too low for too long prone to melting or thinning of the wall, to suppress easily leak.
6, the 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.
7, the electrodes can be heated with a torch dipped in solder powder, as this electrode melting point is too low.
