前言水下等离子弧切割工艺试验研究,是根据生产的需要提出的一个研究项目。主要是探讨水下等离子弧切割的可能性,在8米、6.5米深水下稳定切割100毫米及其不同厚度不锈钢,选择出最佳规范参数。目前,水下切割一般采用火焰或电弧把材料熔化,并以氧气射流把熔化金属从割缝中吹除的方式来进行。但是,这些方法不能适应大厚度不锈钢水下切割的要求。在试验研究工作中,大家分析了等离子
Introduction Underwater plasma arc cutting process test research is based on the needs of the production of a research project. Mainly to explore the possibility of underwater plasma arc cutting, stable cutting of 100 mm and its different thickness stainless steel under 8 meters, 6.5 meters deep water, select the best specification parameters. Currently, underwater cutting generally uses a flame or arc to melt the material and blow it out of the kerf with oxygen jets. However, these methods do not meet the requirements of underwater cutting of large thick stainless steel. In the experimental work, we analyzed the plasma
