Sheet metal working

Greg Blackman finds that automation is the future when it comes to laser sheet metal processing

Profile

At a TWI event in July, Dr Paul Hilton, technology fellow for laser materials processing at the welding institute, gave his personal highlights of 50 years of TWI laser processing. Greg Blackman was there to listen to the presentation

Hybrid welding

Building large structures like ship hulls or railcars lends itself to hybrid welding, a combination of laser and arc welding. Gemma Church explores the technique

Medical traceability

New regulations on unique device identifiers for medical equipment and implants are being phased in by the US Food and Drug Administration, codes that are best marked with a laser, as Rachel Berkowitz finds out

Reclaim project

A laser cell that combines additive and subtractive machining methods for repairing components has been developed as the result of a project called Reclaim. Riccardo Tosi of the UK’s Manufacturing Technology Centre, who spoke about Reclaim at the Mach event in April, sets out the business case for building such a hybrid system
