Abstract
Disclosed is a robot pre-heat and inter-pass welding device that is capable of pre-heating and welding one or more weld joints using a single robot. Pre-heating and welding models are used to ensure that a desirable pre-heat temperature is maintained on the weld piece at the location of the weld. Infrared temperature sensors are utilized to detect temperature of the weld piece, which are transmitted to a controller, which controls the operation of both the pre-heating and welding. Multiple welds can be performed if additional time is needed for cooling, which reduces the overall time required to perform the welding process.
