Italian to English Tech/Engineering Automotive / Cars & Trucks

Context: a summary of activities and capabilities of a company involved in the research and development of car prototypes.

I reparti produttivi sono attrezzati per poter effettuare tutte le possibili lavorazioni inerenti alla fabbricazione di autoveicoli (lavorazioni meccaniche, lastratura, verniciatura, impiantistica, ecc.).

Unfortunately I don't have a technical dictionary on-hand. From what I understand, lastratura means something like: "application of sheet metal through welding". Is there a more concise phrase out there? Maybe just "sheet metal welding"?

Thanks for the help.
