Continuing Development of Resistance Welding Controls

Resistance welding controls have developed over the years, changing the process from an interesting phenomena to a precise technology. From manually operated welders to numerically controlled machines, the user’s demands continually stimulated improvement and extension of the resistance welding processses. New structural materials, production requirements, and the demand for higher quality welds have brought about a high degree of sophistication in controls. The future welders will be machines that can “think for themselves,” with adaptive controls that sense changing welding conditions and adjust themselves accordingly to produce consistently high quality welds.
