Weld Anodized Aluminum

Dec 09, 2019 · There are a couple of work-arounds available that will allow you to avoid welding the anodized aluminum. First, you can do the welding prior to anodizing. Then the finished weld can be anodized as one piece. Depending on your workflow, this may not be possible. If the aluminum parts you need to weld have already been anodized, this won’t be an option. Another alternative is to use a …

Parts can be welded prior to anodizing. The use of 5356 welded rod is strongly recommended, though some discoloration will still occur. 4043 is the worst choice because it will turn a smutty black when anodized. Grinding away the weld before anodizing will result in decreased mechanical integrity and will not solve the appearance variation problem. It is not a good idea to weld after anodizing.

The anodized coating gives the aluminum an attractive, uniform, hard surface that is also highly resistant to corrosion. The characteristics of this aluminum-oxide coating make it very difficult to weld. First of all, aluminum oxide is an electrical insulator, so starting and maintaining a stable arc is difficult.

Guys who do welding anodized aluminum on anodized tuna towers and marine parts can give you some tips on this. Most of them hook up a switch on the torch and pulse weld manually by going from on to off again and again slightly overlapping puddles. This seems to break though the anodized coating.

The bright finish type of anodized aluminum is visually notable from the anodized aluminum because of its shiny and its finish which is chrome-like. This kind of substance includes a thicker sheet of oxides than the standard anodized aluminum, making GTAW welding more difficult and is utilized basically for cosmetic causes. Colored anodized aluminum is again utilized for cosmetic reasons.

Anodizing is simply an electrolytic process that adds a protective coating to the aluminum. To get the best welds, the anodizing should be removed with a flap sanding disc (40-60grit) on the welded areas. 4043 will give the closest color match and 5356 is close.

May 14, 2015 · In fact I go even further and only recommend the 5356 alloy for welding aluminium that is to be anodised. I recommend this to all our anodising clients that have experienced a colour difference. 5356 is a very good colour match when anodised with 6063 in a matt natural finish - it is therefore a good choice for bronze through to black anodised (Type II sulphuric process).

Aug 24, 2020 · The presence of a tough oxide layer on aluminum can lead to issues like porosity, lack of fusion or inclusions in the weld.
