Benefits of Using Pulsed MIG Welding on Aluminum
For years, aluminum has been an extremely reliable and effective metal to use in a vast number of different projects and industries overall. From ship building to aerospace, its quality reigns superior above the many other metals out there. Its resistance to corrosion and overall durability/strength make it extremely popular for situations in which materials will come across moisture. How do you weld this material? However Here at Canaweld, we want to explain why MIG PULSED Welders may be the best solution.
When it comes to effectively welding material, heat control is on of the most important factor some materials such as steel, aluminum transfers heat away from the weld at a much faster rate. Since the material also has quite a low melting point, it has a higher chance of either being burnt or warping. When it comes down to it, aluminum doesn’t have the sufficient weight/volume to transfer the heat effectively in a lot of cases. Some other issues you might come across when welding aluminum include but aren’t limited to:
- The inability to receive a proper bead-like appearance
- Excess spatter
- Bad fusion
Due to all of the reasons above (and the many others we haven’t listed), TIG welding is often considered the best route when dealing with aluminum because of its better heat control and overall weld placement. Even so, TIG welding on aluminum can often be a slow and difficult process, taking a long time to train with others who are newer at welding.
If you’re looking for an efficient and effective way to weld aluminum, pulsed MIG welding might just be the option for you. The huge improvement in quality over the traditional TIG process is all the more reason to look into this alternative and see why it’s so beneficial.
How Does it Function?
Pulsed MIG welding is commonly known as a modified spray transfer process. This means that the power source will be switched between a higher peak and a low background current around 30 to 400 times per second. As this switch occurs, the peak current pinches a droplet of wire and moves it to the weld joint. During this process, the background current will maintain the arc. Since this current contains an extremely low heat, metal transfer will not be an issue.
You may have heard the same warnings time and time again — that aluminum can be prone to certain problems such as lack of fusion, spatter or warping. If you want to avoid these issues, MIG welding is the perfect option. The lower heat input offers similar benefits to using TIG welding.
The advantages to using pulsed MIG welding on aluminum run quite a large list. Some of these benefits include:
- Great directional control over the weld puddle
- Quicker wire feed/travel speeds
- Better control over bead profile & a better quality bead overall
- The ability for use on thick and thin aluminum
- Prevents burn-through
