在自行研制的四坐标焊接机数控系统基础上，针对气体保护直角焊缝轨迹焊接中焊接参数难以确定的问题，在取得一定量实验数据的前提下，应用神经网络算法，建立焊接参数-焊件参数-焊缝成形参数三者之间在实际应用范围内的定量关系。从而实现数控系统根据用户输入的焊接成形要求，结合当前焊接钢板材料、厚度、焊缝倾斜角等参数，自动选定所需的焊接电流、电压、焊接行走速度、偏置、走丝速度，以及保护气体流量，并将这些参数混合编入数控（NC）代码中。
Based on the self-developed numerical control system of four-coordinate welding machine, aiming at the problem of difficult to determine the welding parameters in the welding of gas protection right-angle welding seam, a certain amount of experimental data was obtained, and the welding parameters Parameters - The quantitative relationship between the three parameters of the weld formation in the practical application. In this way, the CNC system can automatically select the required welding current, voltage, welding speed, offset, wire drawing speed according to the welding forming requirements input by the user and the current welding plate material, thickness, Protect gas flow and mix these parameters into NC code.
