Pushing Aluminum Wire - Improving Weld Quality

Aluminum was the original wire type associated with MIG welding and remains a popular choice today. Along with the prevention of weld metal porosity (explained in High Current News Volume 4, Dec. 2010), proper travel of aluminum wire through the utilities and the torch is essential for clean, consistent welds, and can also reduce a few costs.

Just recently the engineers at D/F were able to make a tremendous difference in the quality of the aluminum welds for a customer by suggesting a few simple adjustments to their setup. These changes can be seen in the Before and After pictures below. The customer is welding 50 ft. trailer beds with 3/64" aluminum.

First, there was an opportunity for the torch to be moved much closer to the wire feeder, about 3 feet closer in this case. The less distance the wire has to travel, the less chance for the wire to lose its straightness. Turning the wire feeder 90° toward the torch also helped reduce this distance.

Next, the point at which the wire left the spool was put inline with the wire feeder so that there was no bend prior to entering the wire drive.

These changes also reduced overall bend of the utilities to just a single simple radius into the torch resulting in a tighter, cleaner, more compact overall setup. Along with better wire travel, the customer will see increased contact tip life due to a straighter wire exit (less friction on the tip), and also see reduced cost for replacement utilities as their length has been cut by more than half.
