It is an upgraded version of the DIN6701 series standards and is a comprehensive quality assurance specification for adhesive bonding of rail transit vehicles and their maintenance. This standard provides a framework for creating repeatable and simple bonding processes. The standard covers key aspects such as adhesive joint design, adhesive process planning, production and manufacturing, quality control, maintenance and repair, and procurement of adhesive parts.

The course is taught by Yifa professional lecturers with rich experience in adhesive use. In the morning, professional theories are taught, and in the afternoon, hands-on operations are carried out, combined with on-site visits and internships of adhesive production lines.
Through the training of this course, students can understand the nature and reasons for bonding operations and quality control, saving and controlling costs for enterprises in various aspects such as selecting adhesives, applying equipment, and processes correctly, controlling bonding quality, and avoiding the occurrence of defective products and accidents.
The course content and schedule will be jointly agreed upon by Yifa and the client.
