The Effect of Composite Layer of Stainless Steel Composite Layer Weld of Pressure Vessel on Ultrasonic Testing

The ultrasonic testing technology for the stainless steel composite layer butt welds of pressure vessel is introduced. The feasibility and reliability of the ultrasonic testing technology are analyzed by making the composite layer material contrast test block, which can provide a reference for the draft and application of the ultrasonic testing technology for the butt weld of composite layer material.
