Abstract: Submerged arc welding torches and systems to resistively preheat electrode wire are disclosed. A disclosed example submerged arc welding torch includes: a first contact tip configured to transfer weld current and preheating current to the wire; a second contact tip configured to conduct the preheating current to the wire; an air-cooled first conductive body portion configured to receive the weld current and to conduct the weld current and the preheating current to the first contact tip; an air-cooled second conductive body portion configured to receive the preheating current and to conduct the preheating current to the second contact tip; and an insulator coupled between the first and second conductive body portions.

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 determine whether an acceptable range of the welding-type operation is exceeded based on the total average instantaneous power and the duration of the welding-type operation.
