Bonding strength in the weld to change the top of the place spot machine , by the height of the bottom electrode [ challenge ] spot welding . Because Nevertheless , there is nothing to measure the height of the electrode , the person is performed by rule of thumb , it is necessary to perform a number of destructive test Changeover time . To suppress the variation of electrode height in humans , to stabilize the change in the bonding strength , to obtain a measuring device to increase the production efficiency . In a measuring instrument for measuring the top of the [ SOLUTION ] place spot machine , electrode height of the bottom , and has a display machine movable along the measuring device main body and the measuring device having a shape conforming to the lower horn and upper horn . Stopper protruding integrally is brought into contact with the upper and lower electrodes , each on the opposite side of the display , I was characterized by a numerical value that can be confirmed its position . It is possible to set the height of the electrodes in a simple numerical manage a measurement device is characterized in that choosing a person performing the setup and Products for welding , and can ensure the bonding strength and stable welding .
