What does I-CAR say about disconnecting the battery prior to welding on the vehicle, specifically in regards to airbags?
Response
Per I-CAR curriculum: “The introduction of current or voltage spikes can destroy sensitive electronic parts. When welding:
- Keep the current path short by placing the work clamp as close to the weld site as possible on the same panel.
- Disconnect and isolate both battery cables (remove the negative battery cable first).
- Disconnect the high voltage (HV) battery service disconnect (if applicable).
- Keep the welding machine as far away from vehicle computers as possible.
- Route cables away from computers, wiring, and sensors.
- Remove computers or other sensitive electronic parts if welding closer than 12'' (300 mm)."
“Before beginning repairs on any restraint system, it is critical to first review vehicle-maker service information. Be sure to follow the system disabling procedures to ensure the system has been completely discharged. Even if an airbag looks fully deployed, it may be capable of a second deployment. Disabling the restraint system will help ensure your safety.”
