Alignment Tool For Welding Sensor
Abstract
Alignment tool enables accurate positioning of optoelectronic sensor measuring weld penetration. Designed for use on tungsten/inert-gas welding apparatus, used to adjust position of sensor so photodiode puts out maximum signal. Tangs of slotted cap bent slightly inward to provide spring force holding cap snugly on sensor mount. Tool installed and removed without aid of other tools. Length of pointer adjusted with set-screws. Used with variety of gas cup and electrode lengths.
