热切割与焊接,犹如“裁、缝”是一对亲密的伙伴。由于种种原因,过去的切割技术发展较为缓慢,不适应焊接要求,故不得不大量采用机械加工办法来提高焊口对接面的质量。但随着生产发展和计算机的实际应用,近几年来切割技术有了较快的发展。目前,西德的许多工厂中都采用了自动切割技术来提高生产率和割口质量,减轻了工人的劳动强度,减少了许多机加工序,缩短了零部件的生产周期,降低了产品成本。例如L·H公司生产的真
Thermal cutting and welding is like “cutting and sewing” is a close partner. Due to various reasons, the cutting technology in the past has been developing slowly and it has not been adapted to welding requirements. Therefore, a large number of machining methods have to be adopted to improve the quality of the butt joint surface of the weld. However, with the development of production and the practical application of computers, cutting technology has developed rapidly in recent years. At present, automatic cutting technology is used in many factories in West Germany to improve productivity and cutting quality, reduce the labor intensity of workers, reduce many machining processes, shorten the production cycle of parts and reduce the cost of products. For example, the production of L.H company
