Abstract

In order to solve the problem that an interlayer temperature needs to be controlled in the welding process, the invention provides a pipeline welding seam interlayer temperature control device which is characterized by mainly comprising an electric welding machine, a rotary connection device, a temperature detection device and a temperature relay, wherein the rotary connection device can be fixedly connected to a pipeline and is used for driving the temperature detection device to move; the temperature detection device is fixedly connected to the moving end of the rotary connection device; andthe temperature relay is connected with the temperature detection device by a signal line and is used for controlling on-off of the output end of the electric welding machine. The defect of still carrying out welding when the interlayer temperature exceeds an interlayer temperature range in the welding process is effectively avoided, and welding quality of a welded junction is ensured.

Description

technical field [0001] The invention relates to the technical field of pipeline welding, in particular to an interlayer temperature control device for pipeline welding seams. Background technique [0002] During the construction of high-alloy steel pipelines in power stations, due to the high content of alloy elements, electric heating must be preheated before welding, and a certain interlayer preheating temperature must be reached and kept stable. At present, according to the technical regulations and construction experience, the on-site temperature control method is the armored thermocouple binding monitoring method. In order to facilitate the welding operation, the binding position is generally located within the range of no more than 50mm from the edge of the weld, and it is difficult to effectively measure the interlayer in the groove. The temperature cannot satisfy the effective monitoring of interlayer temperature. [0003] At present, the interlayer temperature cont...
