Energy Conservation in Welding

Abstract

Energy costs have often been disregarded as being a minor part of the total welding co st.lt is discussed here that an inefficient power source consumes unnecessary extra energy which can be avoided by the right design and choice of the equipment.

There are also big differences in energy consumption between the welding methods & processes. Besides the energy costs, heat input also plays a major role with great significance for the metallurgical effects and thermal distortion.

On the macro level, one has to also consider the enormous savings in installation of new power stations apart from the adverse environmental effects of unnecessary power consumption. The problems with electromagnetic compatibility and the possible harmful effects from the electromagnetic fields on human beings is another issue.
