The utility model discloses a Y type groove welds single whole inclined plane notch test panel of cracking test method to one side belongs to the welding technique field, including the experimental test panel that uses of national standard GB4675.1 -84 regulation, form the welding seam between two test panel in this national standard regulation, this welding seam divide into the contained welding seam and middle pilot seam at both ends, and the two test panel terminal surfaces of restricting welding seam department are the wedge face that comprises upper and lower inclined plane, and two test panel terminal surfaces of pilot seam department are a wedge face and a whole inclined plane respectively, and this wedge face and whole inclined plane constitute the oblique Y type groove of pilot seam, modified test panel with test panel difference in the national standard lies in: the adjacent relatively two wedge face parallels of restraining the welding seam on the whole inclined plane of pilot seam sink to being a notch. The utility model discloses can reach the oblique Y type groove of swift, accurate control welding cracking test method pilot seam root groove clearance purpose, simultaneously, can guarantee to restrain the root of weld complete penetration, guarantee whole process of the test and can go on smoothly.
