针对工业机器人中厚板多层多道焊接参数选择的难题，采用基于查表的模糊控制方式，选取送丝速度和焊接速度为控制量，熔丝面积为被控制量，利用Matlab得出了各个变量之间的模糊控制表，用C#编写软件，实现了焊接参数的模糊控制。以25 mm厚对接平焊为例进行试验，结果表明该系统能将焊接后熔丝面积与实际焊接需要填充量的误差保持在5%以内。%An experiment was made to find a solution to selecting thick plate multi-pass welding parameters for industrial robots, using fuzzy control method based on table reading, the wire feed rate and welding speed as control variables, and fuse area as a controlled object. A table of variables for fuzzy control was obtained using Matlab, and fuzzy control of the welding parameters implemented with C# software. Taking a 25 mm thick butt welding as a test, its results show that the difference between the fuse size after soldering and the size in need of soldering is below 5%.
