Can you weld 6061 aluminum with 4043 wire?

I have a client who wants to weld 6061 aluminum with 4043 wire. He says that he has been doing this for years, and that it works well. I’ve never done it myself, so I wanted to ask if this is possible before we do any work on his project. It’s not the type of thing where you want to find out after the fact that there is a major difference between what you thought would happen and what actually did happen…

The difference between 4043 and the 7000 series of aluminum is that ER4043 Silicon Aluminum Welding Wire is a higher strength material than the 7000 series. This means that it can withstand more pressure and stress before bending or breaking, making it ideal for applications requiring strong, durable materials.

However, if you need to weld 6061 aluminum with 4043 wire (for instance), there are some factors you should keep in mind:

The tensile strength of your finished product will be lower than if you had used 7060 or 7071 wire instead. You may want to consider using thicker sheeting so as not to compromise its integrity too much; otherwise, your part could break under normal use conditions after just a few years!

The answer lies in the difference between the two types of aluminum. 6061 is an alloy with a lower melting point than 4043, which means that it will cool down more quickly. When you're welding with 4043, if you don't keep moving your torch around and keep the heat on for long enough to melt through all your layers of metal, then those layers won't be able to fuse together properly; instead they might just stick together like glue (which is bad).

So when we talk about "welding" these two materials together--and why one can do it and one can't--it's really just a matter of how hot each needs to get before they become liquid enough for us humans to work with them easily!

For best results, you should clean and dry the metal surface before welding. If there is any oil or dirt on the surface, it will interfere with the weld and cause it to be weak or brittle. You can use a wire brush to remove excess residue from grinding or sanding operations that have left particles behind.

You should also use tack welds when assembling pieces together before starting your final welds. This will help hold everything in place so that when you start your actual welds they are aligned correctly with no gaps between them (you don't want air pockets inside). It also ensures that both sides are flat against each other so there's no gap between them either; otherwise this could cause weakness later on down the road when pressure is applied through normal wear-and-tear activities such as walking across floors covered by carpeting rather than hardwood flooring surfaces which don't compress like carpets do - thus causing stress fractures over time due simply due lack adequate support underneath our feet while walking around town every day
