1、Copper tube in the production and use of the process of the 3 major problems that often occur:
(1) Copper pipe leakage
(2) Copper pipe cracking
(3) Bending wrinkles, breaks
2, the problem of copper pipe bending
Copper pipe welding process, if not properly operated is very prone to false welding, melting and dissolving through, overcooking and burn-through defects. Virtual welding is a quality problem that often occurs in the welding process of the two devices, resulting from the main reasons are:
● Flare small, brazing solder is not easy to enter, resulting in welding is not secure; ● Welding unevenly, resulting in welding.
● Uneven heating during welding, resulting in part of the brazing solder is not completely heated and melted; ● The surface of the copper tube at the welding place is not uniform, resulting in the welding of the copper tube at the welding place.
The surface of the copper tube at the soldering place has oil, oxides, residual carbon and other substances; ● The quality of the solder itself.
The quality of the solder itself.
As a result, the solder fails to fill the whole length of the socket joint or fails to completely weld the whole length of the socket joint, resulting in leakage. Leakage caused by melting and dissolving through.
