Background
The austenitic stainless steel welding seam has coarse and uneven grains and obvious anisotropy. When ultrasonic waves propagate in the anisotropic welding line, distortion, separation and change of a propagation path occur, so that large attenuation and scattering are generated, and the sensitivity and the precision of ultrasonic detection are directly influenced. Moreover, the small-diameter tube has larger curvature, more clutters and poor signal-to-noise ratio during field detection. Therefore, when ultrasonic detection is performed on the austenitic stainless steel welding seam, the instrument calibration cannot be performed by adopting an ultrasonic test block made of a conventional material, but a simulation test tube with the same specification, material and welding process parameters is manufactured according to the characteristics of a detected workpiece to perform instrument calibration, and the demand of a detection sample is large. The special property of austenitic stainless steel material also brings much inconvenience to the pipeline welding work. First, in the welding of austenitic pipes, inert gas argon is injected into the pipe to protect the root of the weld, so that a gas supply device is separately provided. At present, in sample preparation, an argon guide pipe is usually directly inserted into a pipeline, and then plugging is carried out by simple modes such as pipe orifice plugging, cloth breaking, waste paper and the like, wherein argon is unstable in air supply and serious in air leakage. Secondly, stainless steel cannot contact with carbon steel parts, so that iron ion pollution is easy to occur to cause intergranular corrosion of the stainless steel, and therefore, the welding cannot be carried out on a common carbon steel tool generally; in addition, the stainless steel pipeline welding seam detection precision is high, so the detection sample manufacturing precision is high. At present, the adjustment of the groove gap and the defect position setting are both carried out manually during sample manufacturing, and the setting error of the technological parameters is large and the randomness is strong.
