Laser beam welding
...Out gassing of zinc prevents good welds Beryllium copper: Alloys with higher percentages of alloying agents weld better due to lower reflectivity Copper: High reflectivity causes uneven welding. Materials less than 2.5 mm thick may be coated to enhance weldability Hastelloy-X: Requires high pulse rate to prevent hot-short cracking Kovar: Presence of phosphorous in...
