Abstract

The invention relates to a method for detecting preheating temperature during a welding process, the method is characterized in that a thermal imager with wireless WiFi is used for collecting data of an on-site welding processing workpiece temperature field and thermal images, a wireless infrared thermometer based on IEEE802.15.4 is used for collecting the temperature data, two groups of data can be respectively uploaded to a wireless WiFi gateway and a wireless gateway based on IEEE802.15.4 through a wireless mode, then the gateway and a computer enable wire communication, the analysis of the thermal images and the temperature data by analysis software on the computer is capable of determining the preheating temperature of the welding processing workpiece and the distribution condition of the temperature field, a curve image of the workpiece surface temperature field is drawn, and the alarm and data storage are carried out for overtemperature. The method of the invention has the advantages of no wire arrangement, flexible installation and disposition, and small investment. The method of the invention is completely suitable for a nondeterminacy characteristic of a workpiece position during the welding process, and can increase the primary yield of the welding workpiece in a manufacturing enterprise, possesses large significance for energy saving and consumption reduction, and has large economic value and environmental protection value.

Description

technical field [0001] The invention relates to a detection method, in particular to a detection method of preheating temperature in the welding process. Background technique [0002] Welding is a fabrication technique for permanently joining materials into structures with a given function. Almost all products, ranging from hundreds of thousands of tons of giant wheels to microelectronic components of less than 1 gram, use welding technology to varying degrees in manufacturing. Welding has penetrated into various fields of equipment manufacturing industry, directly affecting the quality, reliability and life of products as well as the cost, efficiency and market response speed of production. [0003] China's steel output in 2007 reached 349 million tons, becoming the world's largest steel producer and consumer, and the steel consumption of welded structures also exceeded 130 million tons, which is equivalent to the annual steel output of the United States, becoming the worl...
