Claim Text:
1. A hybrid laser arc welding assembly, comprising: a laser head aimed at a laser target for producing a laser beam to melt material of at least two metal work pieces to be joined; a torch having a wire electrode aimed at a torch target for forming a metal arc between said wire electrode and the at least two work pieces to melt material of the at least two work pieces; said laser and torch targets being adjacent one another such that the melted material produced by said laser head overlaps with the melted material produced by said torch to produce a hybrid laser arc weld between the at least two work pieces; and a servo motor operably coupled to said laser head and configured to adjust an orientation of said laser head relative to said torch such that said laser target moves relative to said torch target during operation of said hybrid laser arc welding assembly and such that the material melted by said laser head remains overlapped with the material melted by said torch.
