摘要

This report presents several projects undertaken at The Danish Welding Institute to evaluate economic aspects, quality and industrial hygiene in respect of a number of plasma cutting units on the market. The purpose of these projects was to examine whether the development of nozzles and burners in recent years had resulted in such an improvement in the quality of cut in plasma cutting, that the requirements could be satisfied for square cutting in mild steel, for the subsequent welding of fillet welds. This would provide great opportunities for the working of mild steel and HT (high tensile) steel. It is essential for the industrial use of plasma cutting in the cutting of unalloyed steel and stainless steel, that the industrial hygiene arrangements are satisfactory and, in particular, that efficient extraction systems have been established. Economic and hygiene factors are therefore closely connected.
