The possibilities of strong local bonding of glasses and metals with close linear thermal expansion coefficients by means of welding using a femtosecond laser beam were investigated. For the first time, measurements were made of the shear strength of a weld seam between silica glass and Invar alloy, the result being about 26 MPa.
