Problems solved by technology
The disadvantage is that the center pole and the ring pole adopt a planar structure, and because the center pole has a hollow water structure, the radial size is large, and the heat distribution coefficient of the center pole is difficult to characterize the heat distribution of the arc in a fine range.

The invention relates to a device and a method for measuring the heat distribution of a welding arc and belongs to the technical field of measurement and control of the welding arc. The device and the method are characterized in that the invention designs a concentric split pole device for measuring the heat distribution of the welding arc; the concentric split pole device structurally adopts a multi-ring stereoscopic layer structure; and heat of each part is calculated by testing the difference values of water inlet temperatures and water outlet temperatures of a center pole, a middle ring-shaped pole (the number of the middle ring-shaped poles is set according to the measurement requirements) and an external ring-shaped pole in unit time and the heat distribution of the arc is effectively represented by calculating a heat distribution coefficient. The device can be used for implementing the fine measurement on the heat distribution of the welding arc and is suitable for measuring the heat distribution of the arc in the places of tungsten inert gas welding (TIG welding), plasma arc welding (PAW welding) and the like. Meanwhile, the device can be used for providing reference for measurement of the heat distribution in other welding methods. The device has small volume and low cost, is convenient to operate and has high measurement accuracy and wide application prospect.
Description
technical field [0001] The invention belongs to the technical field of welding arc measurement and control, in particular to a device and method for measuring heat distribution of welding arc. Background technique [0002] Arc heat distribution is one of the important characteristics of welding arc. It has a very important influence on the melting of welding wire, droplet transfer, liquid metal flow and weld formation. At present, there are mainly the following methods for arc heat testing: one is to calculate the heat distribution by measuring the arc temperature, and some literatures introduce that in the three-dimensional dynamic simulation of the argon tungsten arc welding temperature field, the infrared temperature measurement method is used to test the weldment. The temperature is measured to verify the correctness of the temperature field simulation. The disadvantage is that the arc temperature is generally above 10000K, and the infrared thermometer can only measure...
