This paper introduces a kind of building steel automatic welding system and it adopts submerged arc welding to complete the welding. There are four processes in the welding, including arc, melting, extrusion and insulation, which are completed by the single chip C8051F021.To ensure the arc and melting processes are accomplished accurately, the voltage and current double closed loop is used to determine whether the arc ignition is success and the melting time are estimated by arc energy accumulation from real-time judgment. Using power devices IGBT, inverse variable technology and programming logic devices (PLD) to constitute a new type of arc welding inverse variable power source. Programming on the PLD with VHDL language and get PWM’s simulation waveform. The results show that the PWM waveform designed by VHDL has high control precision, flexible control, able to adjust the power switch tube dead time, effectively protect switch safety work, and improve the efficiency of welding.
