TECH TIP: Proper Storage For Aluminum Wire Affects Weld Quality and Wire Longevity



This Week's Tech Tip Reveals How Proper Storage For Aluminum Wire Affects Weld Quality and Wire Longevity...

WARNING:
ALUMINUM WIRE WILL GO BAD IF IT IS NOT STORED PROPERLY, REGARDLESS OF HOW LITTLE IT IS BEING USED.
It's hard to deny the impact that Aluminum is making on today's collision repair industry...

In recent years, OEM'S have grown more and more competitive when it comes to meeting Cafe standards for fuel economy. This competition challenges the abilities of industry professionals in how they properly repair, weld and deal with Aluminum in their shops.

For many shops, Aluminum welding has become the norm for day-to-day production. However, there are still shops who may not be as familiar with Aluminum as they are with steel.

Regardless of whether or not you're an Aluminum expert, it is imperative that you remember to store your Aluminum wires when they are not being used. 
It matters because...
  1. Aluminum oxidizes rapidly. This can cause issues with weld quality and overall strength of repair.
  2. When oxidation forms on the Aluminum wire, it disrupts the arc and makes it nearly impossible to maintain it.       
REMEMBER:
Properly storing your wires should not be considered an afterthought. When this step gets overlooked in the shop, its almost always the welder who takes the blame for the issue..             
Proper Storage When not In Use:
When the Aluminum welding wire is not in use, it should be removed from both the welder and torch. 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. 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

TECH TIP: SP MIG 'Hot Start': The Why & How!

SP MIG 'Hot Start': The Why & How! The Benefits & Programming of the SP Pulse MIG Welder's Hot Start Function. Quick Overview It's no secret that welding aluminum is different than steel. One of the biggest differences is how heat is dissipated on aluminum. Steel: Heat stays confined to the area where the heat is applied. Aluminum: Heat rapidly transfers throughout the material.  This causes what is known as a " Cold Start ";  the beginning of the weld bead is weak due to not enough heat at the start causing poor penetration. To counter this we have two options:  Tail-In Method -   You start the weld outside and move in toward the weld join so that the material is pre-heated allowing proper penetration.  Hot Start function  - The cleanest way to program it and avoid the cold start. (See VIDEO below) Solution :  The SP series MIG welder's " Hot Start Function ",...

TECH TIP: How to Save Your Aluminum Wire

Image
Proper storage for aluminum wire when not in use is KEY to making it last longer and for producing quality welds!  Aluminum  oxidizes rapidly , and this can cause issues with weld quality and overall strength of repair.  When oxidation forms on the aluminum wire it will disrupt the arc and will be nearly impossible to maintain a proper arc. ALUMINUM WIRE WILL GO BAD IF NOT STORED PROPERLY  NO MATTER HOW LITTLE IT IS USED   Although Aluminum is becoming more abundant during production, depending on the shop, Aluminum welding may not be a regular occurrence like steel is. Proper wire storage is very important when not in use, as the aluminum  oxidizes rapidly  and this can cause issues with weld quality and overall strength of repair. This is something that is often an after thought or overlooked in the shop, and blame gets placed on welder instead of looking at the wire. When Aluminum welding wire is not in us...
