加热器管板堆焊层超声波检测,传统检测方法是从堆焊层进行检测,此种方法检测时只能将堆焊面粗车后才能进行检测,这样造成大量人力物力浪费。从管板堆焊层母材侧进行检测由于管板母材已金加工不需再加工就可进行检测,从管板堆焊层母材侧进行检测就没有从堆焊层进行检测而造成浪费极大的问题。通过试验提出了管板堆焊层母材侧检测的检测工艺,得出管板堆焊层母材侧检测对于使用碳素钢丝极堆焊的高压加热器是可行的且能极大的减少浪费,降低生产成本。
Heater tube plate surfacing layer ultrasonic testing, the traditional detection method is to detect from the surfacing layer, this method can only be detected when the welding surface rough car, resulting in a lot of manpower and material waste. From the base metal cladding plate side of the test tube base metal has been processed without the need for further processing can be detected from the base plate of the tube blanket layer is not detected from the surfacing layer of waste resulting from testing Great question. Through testing, we put forward the testing technology of the base material side of the overlay welding, and concluded that the testing of the base metal side of the overlay welding is feasible and can greatly reduce the waste ,reduce manufacturing cost.
