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.)


Refinish Precautions

"High voltage battery's performance may decrease if it is exposed to high temperature for a lengthy period. As a result, heat-treatment after painting must not exceed 70°C (158°F) / 30 minutes or 80°C (176°F) / 20 minutes."
