The research results of a gap influence between welding parts upon geometry and strength properties of lap weld joints at pulse laser bonding of thin-sheet austenitic steel are cited. It is shown that gap covering takes place mainly at the expense of upper billet deplanation at the gap increase the dimensions and strength of joints drop, and also cold-hardening of a metal joint arises.
