本文列举了几年来采用弱等离子弧焊接的三十来种产品的焊接工艺及焊接费用。证明弱等离子弧焊具有焊接过程稳定、接头质量重复性好、操作方便等特点,而且在满足装配要求的情况下,可达到或接近100%的成品率。同时证明焊接费用接近或低于常用的钨极氩弧焊、CO_2气体保护焊、自动埋弧焊和手弧焊。实践证明,弱等离子弧焊适合于那些结构简单、焊缝规整、装配质量好、批量大的产品(主要是碳钢)的焊接。
This article lists the welding process and welding costs of over thirty products using weak plasma arc welding for several years. It is proved that the weak plasma arc welding has the characteristics of stable welding process, good joint quality, easy operation and so on, and achieves or approaches 100% yield under the condition of meeting the assembly requirements. At the same time prove that welding costs close to or lower than the commonly used TIG, CO_2 gas shielded welding, automatic submerged arc welding and hand arc welding. Practice has proved that the weak plasma arc welding is suitable for those who simple structure, weld regular, good assembly quality, bulk products (mainly carbon steel) welding.
