Abstract: Methods and apparatus to determine heat input to a weld are disclosed. An example welding-type power supply includes a power converter to convert input power to output welding-type power, and a controller configured to: during a welding-type operation, calculate average instantaneous power values of the welding-type operation for discrete, non-overlapping time periods by multiplying voltage measurements and corresponding current measurements; identify an end of the welding-type operation; determine a duration of the welding-type operation; calculate a total average instantaneous power of the welding-type operation based on the average instantaneous power values for the time periods and the duration of the welding-type operation; and output a first value representative of the total average instantaneous power and a second value representative of the duration of the welding-type operation.

IPC: B23K9/10
Abstract: Apparatus and methods are provided for an engine driven welding-type power system that includes an engine to drive an electric generator to provide a first power output, and a removable welder having an energy storage device to provide a second power output. The system includes a housing having a dock to store a removable welder. While stored within the dock, the energy storage device is recharged by the first power output. Once removed from the dock, the removable welder is configured to operate independently of the power system.
