Problems solved by technology
[0002] When the new high-nickel composite pipe is welded, it is very easy to oxidize inside, and when the interlayer temperature is higher than 100 degrees, it is very easy to have welding cracks and other problems, which seriously affects the welding quality
Moreover, the repair cost of high-nickel composite pipes is extremely high, and some welding cannot be repaired. It is necessary to repurchase the pipes for processing and welding, which is very costly. If the temperature is higher than 100 degrees, wait for the weld bead to cool naturally, and continue welding when it cools below 100 degrees, but there are problems such as extremely low welding efficiency, serious manual work, and high cost. Problems with unsatisfactory results

Abstract
The invention discloses a welding-bead interlayer temperature control device.The welding-bead interlayer temperature control device is used for assisting pipe welding.The welding-bead interlayer temperature control device is characterized by comprising a cooling circulation device, a connecting pipe, overline pipes and cooling winding mechanisms; the cooling circulation device comprises a water inlet and a water outlet, and can control the water inlet-outlet flow and the water inlet-outlet flow velocity of the water inlet and the water outlet; the two cooling winding mechanisms are symmetrically arranged on the two sides of a pipe welding seam; the connecting pipe comprises a water inlet pipe and a water outlet pipe; the two ends of the water inlet pipe are connected with the water outlet and a water inlet pipe opening respectively, and the two ends of the water outlet pipe are connected with a water outlet pipe opening and the water inlet respectively; by means of the welding-bead interlayer temperature control device, the interlayer temperature of welding seams can be reduced during welding; according to the interlayer temperature for different welding requirements, only a flow velocity device and a flow device of cooling circulation need to be adjusted, the welding efficiency of a novel composite pipe is greatly improved accordingly, and construction cost is greatly reduced.
Description
technical field [0001] The invention relates to the technical field of novel composite material pipeline welding technology, in particular to a temperature control device between weld bead layers. Background technique [0002] When the new high-nickel composite pipe is welded, it is very easy to oxidize inside, and when the interlayer temperature is higher than 100 degrees, it is very easy to have welding cracks and other problems, which seriously affects the welding quality. Moreover, the repair cost of high-nickel composite pipes is extremely high, and some welding cannot be repaired. It is necessary to repurchase the pipes for processing and welding, which is very costly. If the temperature is higher than 100 degrees, wait for the weld bead to cool naturally, and continue welding when it cools below 100 degrees, but there are problems such as extremely low welding efficiency, serious manual work, and high cost. The problem of unsatisfactory results. Contents of the inv...
