Crack test of weld zone and diffusive hydrogen experiment

摘要

The present invention relates to a weld crack crack test and diffusive hydrogen test apparatus which can obtain good test results by repeatedly performing a certain test under the same test conditions, and can improve work productivity by automating work processes.;According to the present invention, an electric resistance type heat generating coil is mounted in a hollow refractory and thermal insulating casing, a thermocouple for detecting an internal temperature of the heat generating coil, and a temperature control panel for controlling a power applied to the heat generating coil, A heating furnace for keeping the interior at a constant temperature; A mold provided with a fan and a driving motor which can be mixed with ice and water and which can be mixed with ice and water can be installed on the upper side of the heating furnace and can be filled with a pure metal material and heated with molten metal, chamber; A cooling plate positioned above the mold chamber and having cooling water introduced therein, and blocking the transfer of the molten metal heat in the mold chamber to the upper side; A workpiece mounting part having a vise which is located on an upper side of the cooling plate and movable in a horizontal direction and fixes a test material at a center, and a driving cylinder which moves the cooling plate at one side of the vise and below the vise; And a welder for placing a welding torch on the upper side of the workpiece mounting portion and automatically welding the test material on the workpiece mounting portion in accordance with the test welding method and test conditions, and a diffusive hydrogen testing device .
