Which wire type has limited availability for collision repair welding?

• A. ER70S-2
• B. ER80S-6
• C. ER70S-6
• D. AWS ER70S-7

Answer: (D)

In collision repair welding, the filler metal you pick is guided not only by the base metal but also by what’s readily stocked and commonly used in auto body shops. Some wires are standard, versatile choices that cover typical mild steel, painted or galvanized surfaces, and common thicknesses. Those wires—think of them as the workhorses of shop inventory—are widely available because they handle the everyday repairs you see in a body shop. The wire with limited availability is a specialized option designed for particular high-strength steels and specific welding conditions. It isn’t needed for most typical auto body work, so distributors stock it less, and it can be harder to find when you do encounter it. Because its use is narrower, shops don’t keep large inventories of it, making it the least readily available choice in collision repair settings.
