本文利用水电解产生氢氧气作为新能源对金属气焊、气割工艺及其质量进行了系统的试验研究。通过与氧乙炔切割的对比试验证明,用氢氧焰进行金属切割时,其工艺性能和切割表面质量与使用氧乙炔焰相当,同时具有火焰集中、热影响区小、减少热影响区过热组织等优点。在氢氧气中加入微量添加剂,可改善火焰气氛,使火焰可以调节,满足各种金属焊接需要。通过选配不同焊丝进行低碳钢气焊试验,表明其接头各项性能与氧乙炔焊相近。试验研究结果表明,水电解氢氧焰完全可以取代乙炔进行金属气焊与气割,且具有使用成本低、无污染、安全方便等独特优点。
In this paper, water electrolysis to produce hydrogen and oxygen as a new energy source of metal welding, gas cutting process and quality of a systematic experimental study. Through the contrast test with oxyacetylene cutting, it is proved that the process performance and the quality of the cut surface are similar to the oxyacetylene flame when the oxyhydrogen flame is used for metal cutting. At the same time, the invention has the advantages of flame concentration, small heat-affected zone and overheated tissue in the heat-affected zone advantage. Addition of trace additives in hydrogen and oxygen can improve the flame atmosphere, the flame can be adjusted to meet the needs of a variety of metal welding. By matching different welding wire for low carbon steel gas welding test, the performance of its joints and oxyacetylene welding similar. The experimental results show that the water electrolysis oxyhydrogen flame can completely replace acetylene for metal gas welding and gas cutting, and has the unique advantages of low cost, no pollution, safety and convenience.
