Mig Welding Quarter Panels – A Step-By-Step Guide

If you’re a car enthusiast or a professional mechanic, you’ll know that the quarter panels of a car are integral to its structural integrity. This is why it is important to ensure that they are welded correctly and securely. In this article, we’ll be taking you through the process of mig welding quarter panels, step-by-step.

What is Mig Welding?

Mig welding, also known as gas metal arc welding (GMAW), is a process of welding two pieces of metal together using an electric arc and a consumable wire electrode. This process is widely used for automotive repairs, as it produces strong and reliable welds. When mig welding quarter panels, it’s important to make sure that the welds are clean and secure.

Tools and Materials Required for Mig Welding Quarter Panels

Before you start mig welding quarter panels, you’ll need to make sure you have all the right tools and materials. Here’s a list of everything you’ll need:

  • Mig welder
  • Welding helmet
  • Welding gloves
  • Welding clamps
  • Welding wire
  • Wire brush
  • Grinder
  • Safety glasses

Step 1: Preparing the Quarter Panels for Welding

The first step in mig welding quarter panels is to prepare the metal for welding. Start by cleaning the quarter panels with a wire brush to remove any debris or rust. Then, use a grinder to remove any paint or corrosion from the metal. Once the surface is clean, use the welding clamps to hold the two pieces of metal together in the right position.

Step 2: Setting Up the Welder

Once the quarter panels are prepared, you can start setting up the welder. Make sure that the welding wire is clean and free from any dirt or rust. Then, set the power of the welder according to the thickness of the metal that you’re welding. If you’re not sure how to set up the welder, consult the manufacturer’s instructions.

Step 3: Welding the Quarter Panels

Once the welder is set up and the quarter panels are clamped together, you’re ready to start welding. Make sure that you’re wearing the right protective gear, such as a welding helmet, gloves, and safety glasses. Then, start welding slowly and steadily, moving the torch along the length of the joint. Continue welding until the entire joint is covered.

Step 4: Finishing the Weld

Once you’ve finished welding the quarter panels, you’ll need to finish the weld. Use a wire brush to remove any slag or debris from the weld. Then, use a grinder to smooth out the weld and make it look more aesthetically pleasing. Finally, use a damp cloth to remove any dust or debris from the weld.


Mig welding quarter panels is a simple process that can be done with the right tools and materials. Make sure to take your time and be precise when welding the panels to ensure that the welds are clean and secure. With a bit of practice, you’ll be able to master mig welding quarter panels in no time.
