Abstract
The utility model provides a device for preventing metal welded joint bending test samples from deviating in a test process. The two devices are one group and respectively used for fixing the two end parts of the metal welded joint bending test samples. The two metal welded joint bending test samples are reversed in position, namely an end A of one test sample and an end B of the other test sample are placed together, the end parts of the two reversed test samples respectively pass through two rectangular clamping holes of the device and are fixed by locking bolts on the device. The two test samples are fixed so as to form a whole body; the fixed test samples are tested on a testing machine according to standard requirements (the testing machine need to have enough testing force for the simultaneous testing of the two test samples). As the installation locations of the test samples are inversed, the deviating directions of the test samples in the testing process are opposite to each other; as the test samples are fixed by the device, the forces causing the deviation offset each other, and the deviation problem is solved. The device has the advantages that the deviation problem of the test samples can be ingeniously solved, a circular pressure head bending testing method and the effect of equipment adopted in the method are greatly exerted, and the cost of enterprises and the wasting of materials are reduced.
