Auxiliary tool for pin weld joint tensile test

The utility model discloses an auxiliary tool for a pin weld joint tensile test, which comprises a sleeve (4), and a strip-shaped groove (5) is formed in the wall surface of the sleeve (4) along the axial direction; and the connecting plate (6) is fixed on the outer wall of the sleeve (4) along the axial direction of the sleeve (4) and over against the strip-shaped groove (5). The utility model discloses an auxiliary tool for a pin weld joint tensile test. The workpieces can be machined without being machined; a pin welded on a steel pipe or a pin welded on a steel plate with a certain thickness is directly put into the sleeve from one side of the strip-shaped groove; the pin stretches out of the strip-shaped groove of the sleeve, then the upper chuck of the tensile machine is used for clamping the pin, the lower chuck is used for clamping the connecting plate, and the tensile machine is used for stretching the pin to carry out a pin weld joint tensile test, so that compared with an existing tensile test mode
