Control method for arc welding robot

An industrial robot has a robot unit (10) comprising a fixed base (12) and movable robot components (16, 18, 20) operatively controlled by driving motors (M.theta., MW, MU, M.alpha., M.beta., M.gamma.) provided with absolute position detecting encoders (EC.theta., ECW, ECU, EC.alpha., EC.beta., EC.gamma.). The swivel body (16) among the movable robot components, mounted on the fixed base (12) is mounted, on its mount, with the driving motor (M.theta.) for operatively controlling the same, and is mounted with and holds a battery (46) for supplying a backup voltage to the encoders of the driving motors (MW, MU, M.alpha., M.beta., M.gamma.) for operatively controlling the movable robot components (18, 20). The battery is connected electrically by cables (48, 49) to the encoders (EC.theta., ECW, ECU, EC.alpha., EC.beta., EC.gamma.).

Control apparatus for automatic arc welding machine

A system for converting the welding conditions of a welding robot includes a numerical control unit, which is for controlling the welding robot (8) and a welding machine (7). A memory (3) is included for storing a calculation sequence of a general expression of a given straight line obtained from an X value of a point (U=0) on the given straight line and the slope of the given straight line on a plane in which a welding condition input value is plotted along the X axis and a command value delivered to a digital/analog converter that applies commands to the welding machine is plotted along the Y axis. A value is obtained by substituting a welding condition input value, which is applied when the welding robot is taught, into the general expression stored in the memory (3), the value obtained being adapted as an output value supplied to the digital/analog converter.
