Abstract
The invention provides a device for measuring and controlling the height of an electric arc of argon arc welding. The device consists of a laser distance measuring instrument, a welding machine controller, a data acquisition card, a rotary encoder, an industrial control computer, a welding gun, a stepping motor and an expert database. The laser distance measuring instrument and the data acquisition card acquire the height value of the electric arc in time and send an acquired value signal to the industrial control computer; and the industrial control computer compares the collected data with data in the expert database so as to realize regulation and control on welding parameters. According to the method for controlling the height of the electric arc of the argon arc welding, as the height of the electric arc is effectively controlled according to the steps, fluctuation of welding fusion depth of argon arc welding is obviously reduced, and the stability of welding fusion depth is improved.
