Carrs Welding Technologies Ltd

Laser beam welding (LBW) is a fusion welding technique used to fuse metal parts together through the use of a laser. At Carrs, we focus on the Nd:YAG (neodymium-doped yttrium aluminium garnet) solid-state lasers.

The preferable technology for local repairs is Pulsed Laser Welding due to a few key requirements that negate the need/ability to use other technologies.

Laser Cladding is a welding technique where dissimilar metals are bonded together and a filler is manually added.

Laser marking is the process of using lasers to mark an item by altering the colour or depth of the surface.
There are several applications that benefit from this process, but it is mostly used in the labelling of work pieces and materials. There are diverse techniques available at Carrs that can produce many different surface finishes. Techniques such as annealing, result in a colour change without material removal due to a local oxidization process, caused by heat from the laser source. As a subset technique of laser marking, Carrs can also laser engrave, which is the removal of a layer by layer until a maximum depth of 0.25 mm is achieved (further depths will lead to burnt edges and loss of surface definition).

Tungsten Inert Gas (TIG) welding, also known as Gas Tungsten Arc Welding (GTAW) is a process that uses a non-consumable tungsten electrode and electricity to create enough heat to melt the materials to be welded.

Carrs advise customers on weld preparations and how to improve the quality of their applications.

Carrs are able to offer customers a wide variety of testing methods, depending on the application involved, the operating environment, and the gravity attached to different potential failure modes.
Carrs can leak test with Helium and give a leak rate.
Carrs can cut up a sample weld and mount it for viewing and inspection upto 250X.
Carrs can carry out Non-destructive testing, like dye penetrant, for weld inspection.
SEM and EDX analysis can also be arranged to order.

Welding of metal products to a customer procedure, is most of the work at Carrs. Precision assemblies of steel, aluminium or stainless-steel components are typical of everyday work at Carrs. The example shown, is a light weight rotor which Carrs weld from parts. Its a regular job now, so a pocedure for assembling, welding and testing is set.

Mainly Tig welding, Carrs offers arc welding services when a very large deposit of cladding is required or a cracked component needs sealing. However , as expected arc welding introduces alot of heating in the parts and distortion can be expected. Ask our experts, before jumping in.

Carrs can arrange all types of items to be collected and delivered between our working hours within the UK. Even same day is available (depending on work load).
