Problems solved by technology
However, the pipe girth weld cracking incidents that occurred in recent years are mainly caused by the lax implementation of welding procedures during construction, and the mechanical properties of welds caused by abnormal changes in the number of welding passes, layers and welding parameters Failure to meet the actual requirements cannot be found through non-destructive testing, thus bringing many uncertainties to welding quality control

The invention discloses a collection device for the temperature between welding layers and the number of welding passes, which is installed at the front of the handle of a semi-automatic welding torch; The slag baffle part; the upper end of the installation part of the collection device is combined with the welding gun connection part, and the lower end is combined with the welding slag baffle part, and the collection board installation room is opened on the rear side to install the collection circuit board, and several temperature The sensor installation hole is used to install the temperature sensor. The acquisition circuit board has a three-axis acceleration sensor and is electrically connected to the temperature sensor and the welding management platform, so as to transmit the sensed welding interlayer temperature and the movement track of the semi-automatic welding gun to the welding management platform. Store and calculate the number of welding passes. By collecting the temperature between welding layers in real time and calculating the number of welding passes, the welding quality can be effectively monitored, and data support can be provided for intelligent management, safety warning in the construction process and improvement of welding quality.
Description
technical field [0001] The invention relates to the technical field of welding equipment, in particular to a collection device for the temperature between welding layers and the number of welding passes. Background technique [0002] During the construction of long-distance pipelines, the geographical location of welding equipment often changes with the construction process, and it is difficult for project managers to grasp and effectively manage the working conditions of welding equipment in a timely and accurate manner. At present, in the construction of oil and gas pipelines in special areas such as mountainous areas, hills and dense water networks in my country, semi-automatic welding methods are still mainly used for pipeline welding. The construction quality of this welding method largely depends on the welder's technical level and Responsibility, but the welding process lacks effective monitoring means. However, the pipe girth weld cracking incidents that occurred in ...
