前言所谓单面焊接技术,就是从单面来完成焊接工作。该技术在日本研究得比较早,而且在一些箱形结构和管子等工程上需要施行单面焊接的情况下也已部分地加以应用。一般地谈到单面焊接,其焊接方法的种类也很多:有手工焊、惰性气体保护焊、二氧化碳保护焊、明弧焊等半自动焊接,还有埋弧焊等半自动焊接,还有埋弧自动焊接等。如果仅从单面完成焊接的观点来看,则气电焊、电渣焊、以及熔嘴电渣焊等所谓垂直自
Preface The so-called single-sided welding technology, is to complete the welding work from one side. This technique has been studied earlier in Japan and has also been partially applied in the case of some single-side welding which is required for some box-shaped structures and pipes. Generally speaking of single-sided welding, there are many kinds of welding methods: semi-automatic welding such as manual welding, inert gas welding, carbon dioxide welding and bright arc welding, semi-automatic welding such as submerged arc welding, submerged arc welding Welding and so on. If only from one side to complete the welding point of view, then gas welding, electroslag welding, and welding mouth electroslag welding so-called vertical self
