Hybrid And Electric Vehicle Welding Best Practices

When welding on a hybrid vehicle or electric vehicle, follow the same precautions as when welding on a conventional vehicle. In addition, there are precautions to take with the high-voltage battery. As a best practice, disconnect both the 12 V battery and the high-voltage battery service disconnect. (Note: Always disable the high-voltage battery following the vehicle makers repair information and follow all safety precautions.)

"GM recommends removing and disconnecting the 12 V battery and any modules if welding with-in 12 inches or 300 mm of them. GM also recommends disabling the high-voltage system if welding with-in 12 inches or 300 mm of the high-voltage battery."


Refinish Precautions

"General Motors does not recommend baking the Hybrid vehicles for more than 40 minutes at 140°F or 60°C. Damage to the high-voltage battery may occur." (ambient temperature)
