Abstract

Abstract A computerized welding control system which is capable of controlling a large number of welding heads from a single processor, the processor being the timing instrumentality for the various portions of the welding cycle. The system also includes standard welding circuitry to control the percent heat and the control of the first electrical cycle of the welding cycle. The system includes a data entry terminal for a set of welders within the group controlled by a single processor, the terminal being capable of addressing the computer to determine the time stored therein for various functions within the welding cycle for a particular machine within the group controlled by the terminal unit. The terminal unit also includes capability of changing the times associated with each portion of the welding cycle. The system also includes an automation portion which is capable of sensing various functions within an automated line and feeding data relative to the machines on the automated line to the computer and the computer will utilize this data to generate control functions for both the automation and welding portions of the system.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 83 words
In a welding control system including a general purpose computer having computer cycles and programmed, to provide timing signals for the various portions of a welding sequence, and a hardware control system for the welder, the improvement comprising circuit means for enabling the hardware controller in response to a signal generated by the computer, said computer having an output data buss, said enabling signal being generated at least once for each computer cycle during the operation of said computer and said control system.
Claim 2
Dependent Claim 83 words
In a welding control system including a general purpose computer having computer cycles and programmed, to provide timing signals for the various portions of a welding sequence, and a hardware control system for the welder, the improvement comprising circuit means for enabling the hardware controller in response to a signal generated by the computer, said computer having an output data buss, said enabling signal being generated at least once for each computer cycle during the operation of said computer and said control system.
Claim 3
Dependent Claim 21 words
The improvement of claim 1 wherein said hardware control system is disabled in response to the absence of said enabling signal.
Claim 4
Dependent Claim 27 words
The improvement of claim 1 wherein said hardware control system includes a weld signal producing means, said enabling means being connected to said weld signal producing means.
Claim 5
Dependent Claim 42 words
The improvement of claim 3, wherein said welded signal producing means includes a bistable circuit, said bistable circuit being reset in response to the absence of said enabling signal, said weld signal being absent during the reset condition of said bistable circuit.
Claim 6
Dependent Claim 29 words
The improvement of claim 4 wherein said enabling signal indicates to said weld signal producing circuit the operative condition of said computer and the continuity of said connected means.
Claim 7
Dependent Claim 28 words
The improvement of claim 5 wherein said weld signal producing means is disabled during the production of said weld signal in the event said enabling signal is discontinued.
