Compared to a simple spot weld connection, a hybrid connection of structural glue and spot weld can increase the shear and peel strength of the joint. Generally speaking, there are two main ways to design the structural adhesive arrangement. One is to apply the glue to the important parts of the body according to the experience of the designer. This method is based entirely on the experience of the designer. The position and length of the glue cannot be accurately determined.
