Application of the technique of waveform control in high quality welding

The technique of waveform control has been a tread in welding equipment manufacture.It makes the welding process more easier and gets welding seams obtained more excellent and gets the welding efficiency more higher combining the correlative software with hardware technique.The application of DUO PlusTM technique and Quattro PulseTM technique in MIG welding process and the application of DOC technique in TIG welding process have been introduced in this paper.The result indicated that the application of waveform control technique in welding not only improved the forming conditions of welding seams and decreased the welding spatters,but also developed the quality of welding machine and saved the energy.
