ABSTRACT:
Process for welding two blade parts (9, 10) by a means such as a linear friction welding machine, in which a collar or flange (15) of material to be sacrificed is placed between the contact surfaces (16) or around the latter in order to increase the heat produced by the friction at the leading and trailing edges of the blade. As a result of this arrangement it is possible to start with two blade parts (9, 10) having the dimensions of the finished product, possibly with the exception of the area around the contact surfaces, so that the final machining is very significantly reduced.
