WebThe BIW does not include the closures i.e., doors, fenders, hood, and trunk lid. BIW sheets are mostly joined by spot welds and a typical BIW contains about 5000 spot welds. Failure of these joints due to fatigue phenomenon changes the vibro-acoustic behavior of the vehicle, leading to unwanted noise and vibrations felt by the passengers [1, 2]. WebJul 1, 2010 · It is impossible to discuss BIW joining without considering the inroads being made by structural adhesive bonding. This innovative assembly technique has established a reputation for solving problems related to the cracking around spot welds that occurs as a result of fatigue loads.
