摘要
A method is disclosed for welding one or more fins or longitudinally extended plate like members to tubes or pipes by means of radio frequency resistance heating. A V-gap necessary for the high frequency welding technique is created by deforming the tube to produce an out of round or ovular shape. The welding is accomplished as the out of round tube or pipe is deformed back to a round shape while at the same time bringing the fin or plate like member into contact with the tube or pipe.
