ABSTRACT:
The thermal expansion of parts to be welded to each other is reduced in that one or more of the parts are modified to include expansion slots in the welding area. This limits thermal expansion to the remaining small areas only which are allowed to expand within the slots. Total expansion of such welded parts is thus reduced after solidfication. In most applications, such slots do not effect the total design of the welded parts. If required, such slots can be sealed after welding.
