The invention relates to a laser brazing system, comprising a braze tool having a laser configured to emit a laser beam along a radiation path, and a braze wire tool being configured to guide a braze wire along a wire path intersecting the laser beam. The system comprises a jig comprising a first alignment surface and a first blocking surface, wherein the first alignment surface is configured to be in contact with the braze wire while the first blocking surface blocks at least a first part of the emitted laser beam, and a detector arranged in the radiation path and configured to detect the emitted light of the laser beam passing the jig.

An automated welding system includes a support structure, a plurality of welding heads, and a controller. The plurality of welding heads are each removably, mechanically coupleable to the support structure. The controller is configured to control welding operations of the automated welding system based on an identity of a particular welding head of the plurality of welding heads that is mechanically coupled to the support structure and operably coupled to the controller.

A weld overlay machine assembly includes a carriage to support a hinged index bar and a wire feed assembly. The index bar has an auto height control unit and an index assembly to locate the position of a weld torch relative to the index bar. The assembly is configured to adjust the index bar to interior contours of the vessel while applying a layer of overlay material to a surface therein. The assembly runs along a track in the interior of the vessel. The assembly is configured to transition from sides of the vessel to that of the top or bottom domes wherein the curve of the domes are perpendicular to that of the radial sides. This transition is done without the need to add or remove components to the assembly. This is accomplished by providing the pivoting of the index bar relative to the track.
