Abstract

In the joining of nodular-iron parts having a tubular end to tubular welding parts of steel or cast steel by means of pressure welding with a magnetically moved arc, in order to ensure that a structure of sufficient strength and elongation also appears in the area of the weld without a subsequent heat treatment and that micro-voids are prevented from occurring in order to be able to use this procedure for parts having a high safety requirement, such as, for example, nodular-iron fittings with welding-pipe ends of steel which can be welded on site to liquid or gas lines under pressure, the end faces to be joined are heated to the welding temperature without preheating and/or the end face to be joined of at least one of the workpieces to be welded to one another is in the molten state roughly over the full area before the pressure action.
