METODO PER LA SALDATURA LASER DI LAMIERE METALLICHE PROTETTE CON MATERIALI A BASSA TEMPERATURA DI VAPORIZZAZIONE |
摘要 |
Method of laser welding sheet metal protected by using low-vaporizing-temperature materials, whereby, before being subjected to a laser welding beam along a weld area, two metal sheets are placed on top of each other in such a manner that at least one layer of the said protecting material is located between the sheets at the weld area and that the weld area communicates directly externally of the weld area between the sheets whereby gases generated by vaporization of said protective material may escape from the weld area. |
