Understanding the Different Types of Welding in Collision Repair: Why OEM Requirements Matter

When a vehicle is in an accident, repairs often require more than just panel replacement or paintwork—structural integrity must be restored. One of the most critical parts of that process is welding. But did you know there are different types of welding, and that vehicle manufacturers (OEMs) specify which method must be used to keep your car safe? At Solon Collision in Aurora, OH, we follow strict OEM guidelines to ensure your repair meets factory standards.

Why Welding Matters in Auto Body Repair

Modern vehicles are engineered with high-strength steels, aluminum, and advanced alloys. Each metal responds differently to heat and stress. Using the wrong welding process can compromise crashworthiness, void warranties, and even create safety risks for you and your family. That’s why collision repair facilities like ours use OEM repair procedures as the rulebook.

Common Types of Welding in Collision Repair

1. MIG Welding (Metal Inert Gas)

MIG welding is one of the most common methods used in auto body repair. It involves feeding a wire electrode and shielding gas to join metal panels.

• When OEMs allow it: Mild steel repairs, patch panels, and certain structural reinforcements.

• Why it matters: Provides strong, consistent welds, but only when heat levels and wire types match OEM specifications.

2. MIG Brazing (Silicon Bronze Welding)

Unlike traditional MIG welding, MIG brazing uses silicon bronze filler material at lower temperatures.

• When OEMs require it: High-strength steel (HSS) and ultra-high strength steel (UHSS) areas where traditional MIG welding would weaken the metal.

• Why it matters: Preserves the strength of advanced steels while still bonding panels securely.

3. Spot Welding (Resistance Spot Welding / STRSW)

This process uses pressure and an electrical current to fuse panels together—similar to how vehicles are built at the factory.

• When OEMs require it: For many factory seams, especially in unibody construction.

• Why it matters: Produces OEM-like welds without excess heat, preventing distortion and maintaining corrosion protection.

4. TIG Welding (Tungsten Inert Gas)

TIG welding provides precise, high-quality welds and is often used on aluminum and thinner materials.

• When OEMs require it: Repairs involving aluminum body panels or high-end structural components.

• Why it matters: Offers a clean weld, but requires advanced training and equipment.

5. Weld Bonding (Adhesive + Spot Welding)

This hybrid method combines structural adhesive with spot welding.

• When OEMs require it: Often used in roof panels, quarter panels, and areas where corrosion resistance and strength are critical.

• Why it matters: Mimics factory techniques while reducing heat input and improving overall durability.

Why OEM Welding Requirements Shouldn’t Be Ignored

Every car brand—whether Ford, Subaru, Tesla, or Honda—has strict repair guidelines. Using the wrong welding method can:

• Compromise crash protection in future accidents

• Lead to premature rust or corrosion

• Cause insurance or warranty issues

• Put you and your passengers at risk
