How to MIG Spot Weld Car Body – Lincoln Welders

Introduction

MIG spot welding is a type of welding that is used to join metal sheets together. It is a fast and efficient process that can be used to weld a variety of materials, including steel, aluminum, and stainless steel. MIG spot welding is often used in the automotive industry to weld car bodies together.

In this article, we will discuss the basics of MIG spot welding and how to use a Lincoln welder to spot weld car body panels.

Equipment

You will need the following equipment to MIG spot weld car body panels:

• A MIG welder
• A spot welding gun
• A welding helmet
• Welding gloves
• Safety glasses
• A piece of scrap metal

Safety Precautions

MIG spot welding can be dangerous if proper safety precautions are not taken. Always wear a welding helmet, welding gloves, and safety glasses when welding. Also, be sure to work in a well-ventilated area.

Setting Up the Welder

Before you can begin welding, you need to set up the welder. First, connect the welder to a power source. Then, set the voltage and wire feed speed according to the manufacturer’s instructions.

Attaching the Spot Welding Gun

Once the welder is set up, you need to attach the spot welding gun. The spot welding gun is a handheld device that is used to deliver the welding current to the metal sheets. To attach the spot welding gun, simply plug it into the welder.

Practicing on Scrap Metal

Before you begin welding on the car body, it is a good idea to practice on scrap metal. This will help you get the hang of the welding process and avoid making any mistakes on the car body.

To practice, simply place a piece of scrap metal on the welding table and weld a few spots. Once you are comfortable with the welding process, you can begin welding on the car body.

Welding the Car Body

To weld the car body, simply place the spot welding gun on the metal sheets and pull the trigger. The welder will deliver a short burst of current to the metal sheets, which will cause them to melt and fuse together.

Continue welding spots until the metal sheets are securely joined together. Be sure to overlap the welds slightly to create a strong bond.

Tips

Here are a few tips for MIG spot welding car body panels:

• Use a clean welding gun. A dirty welding gun can cause the welds to be weak and brittle.
• Use the correct voltage and wire feed speed. Using the wrong voltage or wire feed speed can cause the welds to be weak or burn through the metal.
• Overlap the welds slightly. Overlapping the welds will create a stronger bond.
• Practice on scrap metal before welding on the car body. This will help you get the hang of the welding process and avoid making any mistakes on the car body.

Conclusion

MIG spot welding is a fast and efficient way to weld car body panels. By following the steps outlined in this article, you can safely and easily weld your own car body.
