Controller for arc welding robot

Abstract

Abstract PURPOSE:To improve work efficiency by preventing defective work by storing position information and welding conditions when a robot in operation interrupts its operation, and continuing the work on the basis of stored data. CONSTITUTION:A CPU10 is connected via a common signal line 1a to a program memory 11, an instruction position memory 12, an interruption position memory 13, a current-value and estimated-value memory 14, a welding condition memory 15, an input and output control part 16, a positioning control part 17, and a driving part 19 to drive a robot 2 in accordance with a program. The conditions of work are inputted from a keyboard 7 through the input and output control part 16, and a work start and a stop command are inputted with buttons 8a and 8b. Position coordinates X-Z, and angles alpha and beta of a torch 4 and welding conditions when the work is interrupted with the button 8b upon occasion are stored in the memory 13. Consequently, the torch 4 returns to a correct position automatically when the welding is restarted, thereby continuing the welding efficiently as instructed.
