Abstract

A hybrid laser arc welding assembly including a gas metal arc welding torch and a laser arc welding laser head. The torch and laser head are disposed adjacent one another and aimed at targets of a pair of work pieces spaced from one another such that the melted material produced by the torch overlaps with the melted material produced by the laser head, and therefore, the torch and laser head combine to create a hybrid laser arc weld to join the work pieces. The laser head is adjustable dynamically relative to the work-pieces to optimize the hybrid laser arc weld.
