What filler rod do you use for 6061 aluminum?
6061 cannot be welded autogenously, you will have severe hot cracking. You must have a filler metal of a different composition than 6061, that’s why you will not find any 6061 filler metal. Use the 4043 or 5356 and a slightly convex bead to help insure you have enough filler metal added to prevent cracking.
What filler metal is used for aluminum?
Proper filler metal selection is equally important. The most common aluminum filler metals are 4043 and 5356 alloys, both of which are available in wires for gas metal arc welding (GMAW) and cut-lengths (often called filler rods) for gas tungsten arc welding (GTAW).
Which electrode should be used to weld 6061 aluminum?
Furthermore, the correct filler material must be selected. For instance, welding a 6061 alloy with a 6061 filler metal will result in weld failure. Instead, a 5356 or 4043 aluminum filler metal should be used when welding a 6061 base material.
Can you weld aluminum 6061?
There are many aluminum base materials that can be welded successfully with any number of different filler alloys. The base alloy referenced in the above question, 6061-T6 for instance, is commonly welded with at least four totally different filler alloys and can be welded successfully with even more.
Can you weld 6061?
What welding rod do I use for aluminum?
Pick the right tungsten electrode or rod—the best choice for aluminum is typically a pure tungsten rod. Take the time to prepare your aluminum by cleaning and preheating it.
Can I use a 6061 filler metal instead of 6061?
You must have a filler metal of a different composition than 6061, that’s why you will not find any 6061 filler metal. Use the 4043 or 5356 and a slightly convex bead to help insure you have enough filler metal added to prevent cracking.
Why choose Stellite 6 alloy?
Stellite 6 is our most popular alloy as it provides a good balance of all of these properties. The Stellite alloys retain their properties at high temperatures where they also have excellent oxidation resistance.
Can I Weld 6061-T6 with 4043 or 5356?
A: Both are acceptable for welding 6061-T6, but each has advantages and disadvantages depending on the application. An aluminum alloy containing 5 percent magnesium, 5356 generally is stronger and more ductile than 4043.
What is er4043 filler alloy used for?
Filler Alloy ER4043 – While the 4043 filler alloy, a 5% Silicon alloy, is often used to weld 6061 base materials, it is not commonly used when shear strength of the component is a predominant consideration.
