Welding instructions for water pump copper pipe castings and their wall thickness and cooling factors
- Jul 18, 2018 -

Pump copper pipe castings, there are some considerations in the purchase, for product parameters and performance indicators, real-time quotes and price quotes, origin, quality and manufacturers, etc., and these factors are also in the purchase of other castings The basic aspects and factors that need to be considered. Therefore, the water pump copper pipe castings are the same as other castings in terms of purchase considerations, and there is no difference in details. The details may vary.


The welding of water pump copper pipe castings, which are some of the things to keep in mind, are:

The welding of water pump copper pipe castings is generally performed by using copper brazing or silver brazing or hydrogen arc welding by brass hydrogen arc welding wire. If copper brazing is used, then flux is required, and if it is hydrogen arc welding, the corresponding hydrogen arc welding wire is used.


Steel castings, which are sand-typed according to the model, and melt the material into a liquid according to the requirements of the drawings, then pour the liquid into the sand mold and solidify it, and open it out of the sand and conform to the shape of the model, that is, steel castings. The water pump copper pipe casting, although it is a casting, is different in definition from the steel casting, so this is two different castings.


There are no relevant regulations on the wall thickness of the pump copper pipe castings, but there is a lower limit. In the determination of the specific values, it is to see the shape of the casting, the materials used and the process. The cooling of this kind of casting is influential, and it is the external condition and the internal condition. The external conditions are whether there is a cooling system and whether the environment is well ventilated; the internal conditions are the wall thickness of the casting and the internal structure.
