- Synopsis
- This method was developed as a gas pressure welded joint technology using the natural gas with a small negative environmental impact by the replacement of a past acetylene gas in the construction and engineering works, and put to practical use as a dominant method by the environment, safety, and the economy in addition to an excellent splice performance. Moreover, the difference between conctruction persons was reduced by using the developed automatic control unit, and the quality control of the splices with the traceability is enabled, because the construction data is recorded and preserved.
