A magnetically impelled arc butt (MIAB) welding device positioned on the rig floor heats facing ends of a pair of wellbore tubulars. After the facing ends are heated and/or melted, a force application device compressively engages the facing ends to form a welded joint.

A system for the thermal processing of workpieces. In this respect, workpieces can be processed by a plasma jet or by a laser beam. The thermal processing of workpieces is done more flexibly and also less expensive in this respect. A laser processing head or a plasma processing head can be connected by a single shaft element.

A process for producing implants made of a bioresorbable metal, particularly magnesium alloys or zinc alloys, in which the material properties of the magnesium or the zinc are changed and the processing and utilization properties are improved by combining process steps for adjusting the properties of the material and subsequent machining. In this way it is possible to produce thin-walled tubular implants, particularly blood vessel support stents, from bioresorbable magnesium or zinc alloys, which are readily deformable without the risk of fracture during implantation.
