摘要： A technique for heating a workpiece during welding is provided. The technique may comprise a heating system and a welding system. The heating system may be an induction heating system. The heating system is provided to heat the workpiece to a desired temperature and maintain the workpiece at the desired temperature as a weld joint is formed. Because the workpiece temperature is elevated, the difference in temperature between the filler material in the weld joint and the workpiece is reduced. The reduction in the temperature difference between the filler material in the weld joint and the workpiece produces a lower rate of heat transfer from the filler material in the weld joint to the workpiece. The lower rate of heat transfer, in turn, produces a slower rate of temperature decrease in the weld joint.
