Tech Tip: Proper Storage of Aluminum Wire

Key to Making Quality Welds & Longer Lasting Wire: Storing Aluminum Wire When Not In Use


WHAT: ALUMINUM WIRE WILL GO BAD IF NOT STORED PROPERLY (No matter how little is used).

WHY: In today's collision repair industry aluminum is becoming more abundant due to OEM'S racing to meet the C.A.F.E Standards for fuel economy. With this comes the challenge to the industry to know how to properly repair, weld and deal with aluminum in the shop setting.Although aluminum is becoming more abundant in vehicle production; for some shops, aluminum welding may not be a regular occurrence like steel is.

HOW: Proper wire storage is very important when not in use. Aluminum oxidizes rapidly and this can cause issues with weld quality and overall strength of the repair. When oxidation forms on the aluminum wire it will disrupt the arc and will be nearly impossible to maintain a proper arc.
This is something that is often an afterthought or overlooked in the shop, and blame gets placed on the welder instead of looking at the wire.

FIX: Proper Storage when Not In Use
  1. Removed from the welder and torch. 
  2. Once removed storing in either a zip lock freezer bag, or wrapping in cellophane similar to how a new spool would come is the best option. 
  3. When wire is stored properly, oxidation is less likely to form on the wire making for better weld quality, less chance of contamination and longer lasting wire.
 
Proper storage:
Sealed in a bag

Improper storage: 
Left in machine over time
