Seam welding

Introduced: January 2000

Full Title

Full titles differ between systems:

IPC:

Working by laser beam, e.g. welding, cutting or boring > Bonding > by welding > Seam welding

CPC:

Working by laser beam, e.g. welding, cutting or boring > Bonding (soldering by means of radiant energy B23K1/005) > by welding > Seam welding

IPC and CPC are identically structured here. All 5 subcodes exist in both systems.

IPC defines codes here since 2000.
