transportation is required. However, because GE’s HLAW system is portable, large assemblies can be fabricated at the final location.
l Higher efficiency: Because HLAW can weld in just one pass, the new process is far more efficient than its predecessors. This efficiency improvement is applicable in most industrial sectors, including the oil and gas industry, power generation, aviation and rail.
In common with ESAB’s Hybrio system, GE’s HLAW process uses a combination of laser welding and arc welding. With high-power fibre lasers, steels thicker than 12mm can be welded in a single pass at speeds greater than 1 m/minute. The result is a weld of higher quality than can be achieved with traditional multi-pass welding methods (Fig. 3). Over the years, GE says it has pioneered the use of lasers in manufacturing applications ranging from laser hole drilling in aircraft turbine blades to the first use of lasers for surface treatment of fan blades for improved durability. Lasers are also used to weld filaments for lighting products, lamination spacers for generators, and components for X-ray tubes. Able to specify processes such as hybrid-laser arc welding
and low-stress, no-distortion welding, design engineers can take a fresh look at fabrications that might otherwise have

to be assembled in different ways at greater cost or in such a way that performance is compromised. Production engineers can also use these innovative processes to remove cost from existing fabrications. While hybrid-laser arc welding and low-stress, no-distortion welding will not be suitable for every welding application, they represent significant advances in welding technology and warrant close investigation for those projects which could benefit from them. l
