我厂已成功地推广了液化气切割工艺,受到工人们的好评,为国家节约了几十吨的电石。但是,液化气焊接问题若不解决,则将严重影响液化气的推广,因为焊工们除了切割作业外,还不时地需要作气焊作业,如果液化气焊接不解决,还要另外备一套乙炔用具,将是十分麻烦的。我厂一车间气焊组在攻克液化气切割喷咀关之后,又再接再励,开始了液化气焊咀的试验。 Our factory has succeeded in popularizing liquefied petroleum gas cutting technology, receives the high praise from the workers, has saved tens of tons of calcium carbide for the country. However, liquefied gas welding problems if not resolved, it will seriously affect the promotion of liquefied gas, as welders in addition to cutting operations, but also from time to time need for gas welding operations, liquefied gas welding is not resolved, but also prepare another set of acetylene appliances , Will be very troublesome. I plant a workshop gas welding group in the capture of liquefied petroleum gas cutting nozzle off, but then pick and start, began liquefied gas nozzle test.
