The welding technology of boilers, pressure vessels and pipes at home and abroad has made remarkable new developments. Video welding penetration measuring instrument With the large improvement of boiler, pressure vessel and pipeline working parameters and the continuous expansion of application fields, welding penetration measuring system has put forward higher and higher requirements for welding technology. The welding method, welding penetration analyzer system welding process, welding material and welding equipment selected for the welding penetration testing system should first ensure the high quality of the welded joint. The welding penetration detector must meet the requirements of high efficiency, low consumption and low pollution. Claim. Therefore, the detection method of welding penetration width is in this field, the boiler pressure vessel welding penetration testing welding workers always face complex and arduous technical problems, and the boiler welding penetration analysis requires constantly seeking the best solution. Pipeline penetration analysis and detection system has made major breakthroughs in many key technologies through unremitting efforts. The weld seam depth measuring instrument has been successfully applied in actual production. The penetration depth measurement has achieved considerable economic benefits. Dimensional inspection measurements have brought new levels of welding to the welding technology of boilers, pressure vessels and pipes.
In view of the many important industrial sectors involved in boilers, welding depth analyzer pressure vessels and piping, welding depth measurement microscopes include firepower, hydraulics, Wind power, nuclear power generation equipment, microscope petrochemical equipment for measuring welding depth, welding penetration measurement, analysis of coal liquefaction equipment, oil transportation, gas pipeline, beverage, welding penetration deep dairy processing equipment, pharmaceutical machinery, weld penetration Microscope drinking water treatment equipment and liquefied gas storage and transportation equipment, welding seam depth measuring instrument welding technology is quite extensive. Microscope for measuring the penetration depth of welds. Due to space limitations, seam weld depth measurement microscopes are only for boilers, pressure vessels and pipeline steels, advanced welding methods for welding depth gauges, and mechanized and automated weld depth inspection microscopes for welding processes. The new developments in the aspects are summarized below to describe the welding penetration test. Among the three types of steels for boilers, pressure vessels and pipelines, the welding of butt joints for deep penetration testing of boilers is the fastest growing. The detection of T-joints is mainly due to the increasingly tight supply of fuel for coal-fired power stations in the past 10 years. The penetration testing of corner joints and lap joints has become a worldwide urgent need. Cross joint inspection To this end, the efficiency of the boiler must be increased. Welded butt welds are typically tested for a 5% increase in boiler efficiency, and the combined welds formed by fillet welds and fillet welds can be reduced by 15%. The efficiency of the boiler is basically determined by its operating parameters—steam pressure and steam temperature pressure vessel weld penetration measurements. Recently, the steam pressure of the 600-670 MW supercritical boiler produced by the Shanghai Boiler Plant was 254 bar, the hot melt temperature of the steel boiler was measured to be 569 ° C, and the thermal efficiency of the weld penetration depth measurement was about 43%. If the boiler's operating parameters are increased to a very supercritical level, ie a steam pressure of 280 bar and a steam temperature of 620 ° C, the thermal efficiency of the boiler can be increased to 47%. At present, the highest working parameters of the world's supercritical boilers are 350bar/700°C/720°C, and the thermal efficiency of the boiler reaches 50%.
