THE METHOD OF TRACKING WELD LINE USING WELDING TORCH WEAVING

摘要

PURPOSE: A method for tracking welding line using the weaving of a welding torch is provided to measure the voltage of a torch weaving and automatically trace a welding line. CONSTITUTION: A method for tracking welding line using the weaving of a welding torch comprises following steps. The voltage applied on a welding torch is measured by the weaving of a welding torch(1). The measured voltage is compared, one between a maximum voltage value and a minimum voltage value is designated, and the designated voltage value moves a welding carriage according to the position of the measured welding torch, thereby enabling automatic welding without the use of probes.
