Different types of welding rotator

As we all known that the welding rotator play an important role in welding process.In the meantime the Welding Positioner,welding turning rolls are necessary too.Do you know the types of welding rotator.

1. Forged rotator: The impeller and the entire shaft are made of molten steel casting, the rotator thermal stability of the best, but difficult to manufacture difficult. And out of the problem to repair difficult.

2, welded rotator: This rotor is welded for some time, the thermal stability is good, but the welding technology is very demanding.

3, Set-type rotator, the impeller of this kind of rotator is sheathed on the large shaft through the heat sleeve, the manufacturing cost is low, but it is easy to be loosened under the high temperature, and is usually only used in small and medium-sized units.
