Can You Electric Weld on a Car?


Professional projections estimate a 4.6% annual growth in the global welding market between 2021 and 2028. The industry is expected to grow from $20.99 billion in 2021 to $28.66 billion by 2028

If you want to take advantage of the industry’s lucrative projections, it’s important to be ready for all possible situations and concerns, such as whether electric welding on a car is safe.

nexAir is armed with all the welding supplies to get every job done. We have the KnowHow to address all your welding concerns on automotive vehicles. 

Let’s discuss the consequences of electric welding directly on a car.


Welding and Safety: What You Need to Know

Welding is the most common way to attach metal components and perform other metal-related fixes for vehicles. However, electric welding might not be a good idea.

To put it simply, welding on a vehicle can cause damage to its electronic and other vital components because the electricity that courses from the welding equipment might travel through the electronics attached to the car’s metal parts.

Here are some of the dangers of welding directly on a car’s metal frame:

  • You can damage the car battery due to high voltage electricity from the welding torch.
  • The car radio which normally gets electrical power from the car battery can get damaged.
  • It can deploy the airbag if the welding impact is mistakenly interpreted as a crash.
  • It can fry the car’s electronic control unit (ECU) which controls all the electrical parts.
  • The risk of fire accidents increases due to the car’s circuitry, wiring, batteries, and fuel because they’re sensitive to sparks and increases in heat.

As you can see, the electric current released by the welding torch could indirectly damage car electronics. It can also unintentionally deploy airbags. So, you would ideally want to perform the actual welding on a separate surface instead of directly on the vehicle.

Keep these safety tips in mind when electric welding on a car:

  • Avoid welding activities near flammable objects and environments; this includes emptying the fuel tank beforehand to reduce the likelihood of fire accidents.
  • Always disconnect the ECU, battery, and all attached wires before getting started.
  • Disconnect as many parts as possible from the car’s electrical circuitry, including the control panel, radio, and wires; you may also remove the windshield wipers.
  • Use grounding clamps to catch excess electricity on the ground and prevent damage to the car battery and other sensitive automotive equipment.

As much as possible, remove the car part that you’re welding. This is the best way to prevent accidents and car damage. In any case, keep a fire extinguisher near the location where you’ll be performing welding activities.
