FORMING METHOD FOR AUTOMOBILE BODY HEMMING SECTION

摘要

PURPOSE:To cover the end edge section of the coating by filling an adhesive in the gap of the hemming section of an automobile body and expanding the adhesive by the heat treatment performed to harden the coating. CONSTITUTION:An adhesive 7 is coated on an outer plating 1, and the outer plating 1 is folded so as to cover the edge section 2a of an inner plating 2, with the adhesive-coated face facing inward. The electrodeposition coating 6 is then applied to the outer plating 1 and inner plating 2, and the heating and hardening process of the coating is performed. At this time, the adhesive 7 is expanded by the thermal expansion filler action and covers the end edge section 6a of the electrodeposition coating 6.
