Is laser welding the future of pressure vessel and pipe fabrication?<\/h2>\n<\/div>\n
The Toolform Programme has assessed the feasibility of using laser welding to add to the existing arc welding expertise already in use by a Sheffield pressure vessels fabricator. The aim was to produce high quality welded components.
\nThe programme is funded by the DTI, Yorkshire Forward and Objective 1.

The brief.<\/h3>\n
\n
\n

A client of ours, Portobello Fabrications<\/a>, located in Sheffield, is a leading fabricator of heat exchangers, chemical tanks and pressure vessels. These are for use in the oil, gas and chemicals industry as well as water, food, pharmaceuticals, power generation, and nuclear industries.
\nThe materials used in these products must always be welded reliably to meet stringent welding standard requirements.<\/p>\n

Portobello Fabrications specialise in producing components that see extremes of corrosive environment, elevated temperature, or pressure from 2-20 bar. This makes it vital to obtain reliable welds.
\nBy implementing laser welding, considerable savings in set-up times and efficiency can be attained over conventional arc welding.<\/p>\n

Material and equipment.<\/h3>\n

Tubes of 304L stainless steel and IMI 130 Grade 2 titanium, with bore size varying from 40mm to 200mm and 1.5mm, 2mm and 4mm wall thickness.
\nThese were joined using an HL4006D lamp pumped Nd:YAG laser manufactured by Trumpf; with a Kawasaki JS30 robot used to manipulate the beam during welding operations.
\nThe flexibility of fibre optic beam delivery and use of robotic manipulation, were ideal for this application. Particularly for angled butt joints and various configurations of fillet welds, as well as for straightforward circumferential butt welds.<\/p>\n

Advantages.<\/h3>\n<\/div>\n
\n

Amongst the advantages of choosing laser welding over arc welding, is the ability to repeatedly weld standard sizes according to programmed routines. This reduces welding time and ensures that manpower can be more effectively distributed.
\nWelds on non-standard configurations can also be achieved with similar results to the manual arc welding procedures currently employed by Portobello.
\nProvided that acceptable fit-up can be achieved prior to joining, laser welding can produce single pass welds in the wall thicknesses evaluated with full penetration at welding travel speeds up to 5m\/min.<\/p>\n

Leading the industry are Trumpf-Laser<\/a>\u00a0where laser welding is a permanent part now of the electronics production.<\/p>\n

Alternatively ESAB, leader’s in new\u00a0welding and cutting equipment\u00a0have produced a Hybrid laser welder…..<\/strong><\/p>\n

ESAB\u2019s Hybrio<\/a>™ hybrid laser welding technology combines the deep weld penetration and low heat input associated with laser welding with the excellent weld properties.
\nAlso, superior gap tolerance of Gas Metal Arc Welding (GMAW).
\nA radically new welding alternative, it produces extremely narrow and deep welds at very high travel speeds.
\nIn a single pass, the Hybrio™ process can often achieve what might require multiple weld passes using a conventional fusion welding process.
\nHeat input to the part is reduced, as is the associated weld shrinkage and distortion that can make post-welding geometry unpredictable \u2013 and costly to repair.<\/p>\n

The welding process.<\/h3>\n

Using GMAW in combination with a laser, the Hybrio™ process solves laser-only welding\u2019s limitations. These concern it’s ability to produce acceptable welds in joints with less than perfect fit-up between parts.
\nThis enables a widened, more robust process envelope by a factor of three compared to a conventional laser-only process.
\nGMAW also allows users to add filler metal to adjust the weld\u2019s metallurgical properties and create beads and fillets, while the slower cooling rate reduces hardness.
\nThese features are especially beneficial when joining high performance carbon and stainless steels.<\/p>\n
