چکیده مقاله
In this investigating , the increase in demand for electricity in Europe requires a continuous search for new sources of energy,engineering and technology solutions Maintaining the current level of electricity production requires not only repair and modernization of the operating units, as well as construction of new blocks of supercritical and ultra supercritical Increasing thermal efficiency while reducing energy costs is possible through the use of finned tubes for heat exchangers Welding contact currents frequency HF is a variation of resistance welding which uses high frequency properties of the welded contact surface heating elements to melt temperature, and combinations thereof by pressure finned tubes used a heat recovery steam generator HRSG is the core facility of a combined cycle thermal power plant that recycles thermal energy from a gas turbine and creates high temperature and high pressure gas This paper presents the technologies of finned tubes, with particular emphasis on high frequency electric resistance welded finned tubes developed Standard specification for fin tube technologies, Inc is ASTM A 498 and ASME Standards used for Metallography and tensile strength for fusion weld
