On Thursday 23 March, Neil Main (MD at Micrometric), will make a presentation at the Association of Industrial Lasers (AILU) Symposium at Belton Woods Hotel, Grantham, on the laser welding of 316 stainless steel.
One of the most commonly welded Austenitic stainless steels is 316 grade (1.4401) and the low carbon grade 316L, which are routinely used in food machinery and surgical steel applications owing to the excellent corrosion resistance this material exhibits.
Historically, 316 stainless steel has been laser welded with excellent results and no cracking. Recent changes in the method of manufacture of 316 stainless steel destined for bar products have, while still keeping within the chemical composition limits of the 316 spec, made the machinability of 316 much better but worsened the weldability. The influence of the producer, chemistry and destined product form will be discussed and contrasted with plate product of the same material specification.
The Industrial Laser Applications Symposium (ILAS) takes place from 22-23 March at Belton Woods Hotel and covers a whole range of laser applications presentations from end-users. Held every 2 years, this is the 5th Symposium organised by the Association of Industrial Laser Users. From 2013-2015 Neil Main was President of AILU.
