FAW-Volkswagen Details ID.AURA T6 Quality Checks at Foshan Plant

The report said the process begins before the production line, in material laboratories. For the ID.AURA T6, high-strength steel accounts for more than 80% of the body, thermoformed steel accounts for 29%, and some key positions use 2000 MPa-grade thermoformed steel. Samples are put through tensile tests that record permanent deformation and fracture, then calculate yield strength, tensile strength and elongation against design requirements. Tested samples are kept for one year for archiving and later review. Scanning electron microscopes are used in development validation, sampling tests and failure analysis to look for inclusions and microcracks on surfaces or cross-sections, with engineers tracing findings back to materials and processing.

On the production line, the Foshan plant uses KUKA industrial robots and the Konzern framework for both efficiency and quality, according to ifanr. Before a body enters, RFID identifies the model and calls up the corresponding fixtures. Some 330 clamping points secure the body, and 12 robots work simultaneously from different directions to connect the side panels with the lower body. One cycle takes 51 seconds, and the system can support mixed production of up to eight models. The main welding area is fully automated. Key welding parameters are collected at 100%, and current and voltage at key stations are monitored in real time to control welding quality.

For battery assembly, ID-series battery packs, including that of the ID.AURA T6, undergo the same reliability validation. This includes more than 200 hours of vibration testing using road-load spectra collected from real vehicle durability tests, followed by disassembly and inspection. A battery salt-spray test lasts 42 days, seven times the six days required by Chinese national standards, to check corrosion resistance against coastal salt spray and northern de-icing salt. The report also noted the handling of thermal conductive adhesive. Because gaps between cells and the cooling plate impede heat transfer, the adhesive fills them; insufficient adhesive or bubbles can affect heat dissipation. FAW-Volkswagen moved the dispensing process before the stack is placed into the pack, allowing real-time monitoring of the adhesive layer and pressure filling of gaps between the stack and the cooling plate. Although the stack has already passed an insulation test, it is tested again after transfer to the next line. The PACK line added an independent insulation pre-check before high-voltage connection welding, because transfer can cause new problems such as scratched insulation film or fallen foreign objects.

Controls continue through final assembly until the vehicle leaves the line. Battery airtightness, laser welding continuity and multi-year retention of operation data are all part of checks intended to protect vehicle safety, the report said. After assembly, each ID.AURA T6 undergoes a final line inspection. FAW-Volkswagen then randomly samples vehicles that have passed final inspection for an Audit whole-vehicle quality review, in which reviewers take the customer's perspective and look for flaws. The ID.AURA T6's Audit review includes more than 1,500 checkpoints, 240 minutes of static evaluation and dynamic testing on multiple road conditions. Reviewers demonstrated appearance dent and bump standards that distinguish the visible angle and severity of defects; details that might look acceptable to an ordinary observer can be judged as requiring a return to the factory.

FAW-Volkswagen used the slogan 'Quality and intelligence have no shortcuts; carmaking is not rapid prototyping' for the event. Yu Jiaqi, head of the company's public relations department, said at the event: "Product problems can be solved through recalls, but if an accident occurs, users' lives cannot be recalled." The report said this reflects the company's position that faster car development cannot come at the cost of omitted quality validation.

The report also described how the ID.AURA T6 fits FAW-Volkswagen's localization push. The company summarizes its development as following, accompanying and leading. It began by importing German technology and manufacturing standards, then built local R&D teams and adapted to Chinese user habits, and now lets Chinese market demand guide product development earlier. FAW-Volkswagen describes this as 'Chinese users set the questions, Volkswagen answers locally.' Chinese teams define products more actively and work with shareholders and local partners so local needs enter design from the start. The ID.AURA T6 uses the CEA electronic and electrical architecture, organized around central computing and zone control and supporting software upgrades, to provide a base for cockpit and assisted driving functions. It supports four-zone voice interaction and dialect recognition. FAW-Volkswagen worked with CARIZON and Horizon Robotics on a local assisted driving solution tailored to common Chinese scenarios such as mixed pedestrian and vehicle traffic, complex intersections and weaving non-motor vehicles. The ID.AURA T6 completed 'two winters and two summers' system vehicle testing in Heihe and Turpan.

The report said the ID.AURA T6 continues Volkswagen's quality control system while rethinking what a car in China should offer. FAW-Volkswagen is compressing development time to match demand for new products, but efficiency is only a bonus; quality is an uncrossable bottom line, and the pursuit of efficiency cannot justify a drop in quality.
