The welding rod you chose must be the proper material to fuse with the alloy of aluminum you are welding. You can use Aluminum welding rods on dissimilar metals copper to aluminum and even galvanized steel.

How to use aluminum welding rods. You want the metal to melt the rod not the flame. When everything is cooled off youll have a strong joint. Clean your aluminum remove any oxide and file the edges that will be joined Avoid pulling while weldinginstead push at a 10 to 15 degree angle Use multiple pass straight beads to improve the overall appearance of the weld and help to avoid defects Use a heat sink which will absorb extra heat and allow you to weld slower.
To answer this question in short yes you can use some welding rods as brazing rods. Trying to melt the rod itself is a sure headache. Stocks in huge qty.
The process of using aluminum welding rods is nothing out of the ordinary and simply requires reasonable attention to details and settings and the welder can get surprisingly superior results. When you sweep the tip of the rod through the joint it should melt in. Hold the electrode vertical to the aluminum workpiece with straight-end angle.
Ensure you have the correct reference point on the type of welding for specific electrode eg. Ad We Stock Duplex Super Duplex Electrodes. The welding current affects the penetration profile of the weld that will be.
Ad We Stock Duplex Super Duplex Electrodes. If not heat the joint more and check it again with another sweep. The key step is to scratch the rod on the surface to break through the aluminum oxide coating and make the metal flow like solder.
In the SMAW process also commonly referred to as stick welding the welding rod aka. There are some metals which are considered to be a good choice when it comes to brazing like iron nickel steel aluminium. Dont worry if the tack welds look like incomplete fusion.

As mentioned earlier aluminum welding rods are a type of filler metal that is used to join two base metals either by using a torch or an electric current. Apply the flame to the joint until its hot enough to melt the rod. The welding electrode which is commonly known as welding rod is a piece of flux-coated metal wire that also acts as filler when used in the welding process known as the shielded metal arc welding or SMAW.
Now the final result may not be as good using the intended rod but it can get the job done. Stick electrodes melts. This revolutionary product designed specifically for aluminum welding uses no flux making it easy to use and environmentally safe.
A low working temperature of 732 F 392 C. Each welding electrode has a specified type of current to be used ie. Start by tacking the aluminum workpiece together.
Use the proper welding rod. The incident is caused by the flux peeling off from the metal edges. In fact you can use it on almost any non-ferrous metal except stainless steel.
Seasoned welders sometimes overlook this easy method to weld repair items like alternator housings aluminum boatsetc. Some can only be used with DC or AC current or even both. Just like when soldering copper pipe.
For electrical arc welding the proper current and amp settings are essential to achieve the proper heat range. We Offer Specialized Welding Solutions in ER2594 ER2209 2205 DSS 2507 Duplex SDSS.
