What is the best welder for aluminum welding?
The answer to this question is more than just one weld – it depends on what type of welding application you will use the welder for. For example, if your application falls into the category of high frequency arc welding, you should find a welder that has dual frequency capability. Meanwhile, if your application falls into the category of low frequency stick welding, you need a flux core wire feed welder.
The welding process can be daunting, especially if you’ve never done it before. But don’t let this long list of things to learn scare you – we’ve got the answer!
We don’t want to keep you in the dark – so here are some basic but important facts about aluminum welding that will help you find the best welder for your job.
Aluminum is a lighter metal than steel or iron, so the welders and the machines to weld with them are smaller.
Because of its light weight, aluminum does not need large amounts of heat to be melted. As such, welder settings for aluminum tend to be lower in comparison to other materials.
This lightness has another effect – it can be easily drawn out by the air if left unprotected. So when welding aluminum, it’s important to keep it covered with a mask and gloves.
It is also easier to burn, so you have to be extra careful when handling the material before, during and after the welding is done.
You’re probably wondering how do you know what settings you should use for your job? First off, always check with your instructor or mentor or ask for their recommendations. Take note of what kind of aluminum you are working with (there are several types) because each one needs a different welder setting.
The most commonly used aluminum is called “hot-worked” aluminum. This is when the material has been previously heat-treated to improve its strength and hardness. Basically, this means it is harder than raw aluminum, so you need to use a higher-heat metal than usual for your welding application.
On the other hand, “cold worked” aluminum requires a lower heat because it has already been tempered and hardened in preparation for hardening again. This type of aluminum does not need as high of a heat setting for welding, but you will have to work at a lower temperature as well to keep the welds stable.
To help you make an informed decision, here are three of the best welders for aluminum welding:
