Transition pipe welding system and process

Abstract

The invention provides a transition pipe welding system. The transition pipe welding system comprises a cable, a transition pipe, a heat insulation protection layer, a temperature measuring probe and a cooling device, wherein the cable comprises an outer sheath, a smooth aluminum sheath and a water blocking layer from outside to inside, a horn mouth is formed in the end of the smooth aluminum sheath, the heat insulation protection layer wraps the outer side of a water blocking layer and is located below the horn mouth, the temperature measuring probe is arranged in the horn mouth, the transition pipe is provided with a conical surface, the transition pipe sleeves the horn mouth, the conical surface of the transition pipe is attached to the inner side of the horn mouth, and the outer side of the smooth aluminum sheath is connected with the cooling device. The invention further provides a transition pipe welding process. The transition pipe welding system has the beneficial effects that the situation that the cable is scalded when the transition pipe and the smooth aluminum sheath are welded can be well prevented, and the welding strength and the sealing performance of the transition pipe and the smooth aluminum sheath are ensured.

Description

technical field [0001] The invention relates to a welding system, in particular to a transition pipe welding system and process. Background technique [0002] Since the smooth aluminum sheath layer of the smooth aluminum sheath cable is closely combined with the water blocking layer, if the connection sealing problem between the smooth aluminum sheath cable and the copper sleeve of the cable joint or the terminal tail pipe is dealt with by the conventional process, it is easy to burn the cable and cause a series of problems. Therefore, to deal with this problem, it is necessary to carry out special treatment on the smooth aluminum sheath of the cable, that is, to expand the fracture of the smooth aluminum sheath into a bell shape to increase the distance between it and the outer semiconducting layer. The transitional aluminum tube is welded at the mouth, and then the subsequent sealing and fixing are carried out. In the above process, the welding process of the transition t...

AI Technical Summary

Problems solved by technology

In the above process, the welding process of the transition tube is particularly important. If continuous welding is performed in a certain area, it is very easy to cause the temperature in the local area to be too high and burn the cable. Improper temperature control during the welding process will also cause damage to the cable.
