From my experience, and tainted with my skepticism, anybody who

I have a publication from Hexcell that discusses what gives the superior
bond, welding, riveting, or chemical bonding. In their study, the chemical
bond was superior as stress was more evenly distributed and not isolated at
the fastening points (rivets) and surrounding material was not fatigued or
weakened by heat (welding). But to be honest, the report might be slanted
since they manufactured the adhesives, after all would they say their product
was inferior?
