Many parts in the dehumidifier are assembled by welding, so the quality of the welding process and its suitability will directly affect the performance of the dehumidifier, thus extending to its dehumidification effect. What should be paid attention to in the welding process of the dehumidifier?
The first is to correctly grasp the copper sleeve insertion gap and depth in the copper pipe dehumidifier, otherwise it will affect the strength of the connection part of the dehumidifier. Generally speaking, the shorter the insertion length of the brazing part of the dehumidifier’s piping, the stronger the strength. will be lower. When the capillary of the dehumidifier is welded with the filter drier, the depth of the end face of the inserted capillary from the end face of the filter screen should also meet the requirements.
Secondly, the control of welding flame and temperature is also very critical. If gas welding is used for brazing, neutral flame can be used. If the welding temperature is too high or too low, it is not good for the welding quality. The basic reason is that it is lower than the melting point of the copper tube of the dehumidifier. It is best to do some cleaning treatment. The copper pipe joints of the dehumidifier must be clean and free of burrs to avoid adverse phenomena.
