Abstract:
The present application relates to an apparatus for and a method of forge welding elongate articles (1, 2), such as tubes, together. In addition to electrode (12, 13) assemblies (9) for heating the article (1, 2) ends with high frequency resistive heating, the apparatus includes a coil (3) for induction heating the articles (1, 2) before or after welding, as well as means for cooling the welding seam.
