Sport or seam explosive welding machine - for welding thin titanium sheet to thick steel base

摘要

A device for welding a corrosion-reistant metal sheet, e.g. Ti, to a substrate, e.g. steel, where the two sheets are placed on a base. Over the base is a parallel carrier-bar, which can be raised and lowered so the sheets can be inserted and clamped, and which also carries several explosive charges and means for their detonation. The explosive used is e.g. pentaerythrityl tetranitrate (PETN).
