The welding speed has great influence on the overall dimension, appearance and internal quality of a welding seam, and the accurate welding speed value is obtained, so that a designer can formulate a more reasonable welding process. For automatic welding, the common way to measure the welding speed is to detect the speed of the welding carriage by using an encoder, and then the speed is converted and displayed. There are also documents which adopt a method of installing rollers on a welding gun to convert the welding speed into the rotating speed of the rollers, and then the rotating speed is displayed by a velocimeter, so that the accuracy of the obtained result is influenced by the running surface of the rollers, and the whole device is not light and stable enough. In the manual welding process, it is difficult to directly detect the welding speed due to the influence of the operator. In the conventional method, the total length of a welding seam is divided by the total welding time to roughly estimate the welding speed, and the method is time-consuming, inaccurate, incapable of intuitively obtaining the value of the welding speed in real time and in need of improvement.
