US 2011/0209814 A1 · METHOD OF AND APPARATUS FOR WELD-BONDING WORKPIECES

Abstract

A method of weld-bonding a plurality of workpieces to produce an improved peel joint, includes the formation of an adhesive layer and a weld nugget, and the securing of an adhesive cover relative the workpieces during bonding. The method is operable to partially prevent the migration of fluid adhesive material during construction, and to transfer at least a portion of peel loads to the shear strength of the adhesive material in the produced joint. The method may also be performed utilizing other interconnection means such as clinching or riveting.

Dependent claims

A method of joining a plurality of workpieces, said method comprising the steps of:

a. securing an adhesive layer intermediate and adjacent the workpieces, so as to interconnect the workpieces in a fixed relative position and present an exposed adhesive surface;
b. securing an adhesive cover in a fixed position relative to the workpieces and exposed adhesive surface, so as to prevent the migration of adhesive in that direction during construction;
and
c. further interconnecting the workpieces to further secure the workpieces in the fixed position.
