Volvo Position Statement: Electric Vehicle (EV) Welding
I-CAR · December 13, 2024 · Volvo
Summary
This Volvo position statement outlines critical safety precautions for welding on electric vehicles (EVs), including mandatory disconnection of the 12 V battery and de-energizing the high-voltage (HV) system. It also specifies when HV components or the battery must be removed due to proximity to welding or visible casing damage, and recommends squeeze-type resistance spot welding (STRSW) as the preferred method.
What to do on the job
Always disconnect the 12 V battery, de-energize the high-voltage system, and remove the HV battery or electronic units if welding is performed in their immediate vicinity.
How to use it
Use this position statement to justify the labor and safety operations required for EV welding, such as de-energizing the HV system, disconnecting the 12 V battery, and removing the HV battery or components when welding in close proximity. It also supports the use of STRSW as the OEM-recommended welding method.
