How to do aluminium welding?
Aluminium welding is a very common thing, which is used in welding workshops. Every welder should have knowledge of aluminium welding.
Welding
Since the world requires iron and steel a lot and lot, the need for welding is more and more.
There are many different types of welding used in the industry, in order to shape up the raw metals.
We are detailing those types and regular updates in our blog.
Here, today we are detailing something that is very useful for welders, who can go to a higher level in their welding career.
As all we know, our Indian Welders Welfare Association is performing a vital role in the welder’s life.
And also, the association always provides many benefits by delivering, job offers and posting many useful topics in the welding industry.
Now, the Indian Welders Welfare Association made an article, which will be very useful for all the persons who are in the welding industry.
Aluminium welding
Aluminium is a very common thing, that is used in Welding workshops. By working on this, the welder needs to be done at a low temperature, otherwise, the material would end up in blowing holes.
Welding aluminum is quite difficult than welding steel, as it requires more guidance and consideration. Aluminum welding looks clean, smart only when the welder understands everything that’s involved.
Many tools and techniques are there to weld steel.
But, Aluminum welding has it’s own technique and equipment.
There are five important aspects of aluminum welding in the preparation of the metal.
- Remove oil, grease, and water vapor using a solvent or mild alkaline.
- Remove the surface oxides with a wire brush or strong alkaline or acid.
- Assemble the joint.
- Keep the joint dry.
- Weld within a few days.
There are many ways used to weld aluminum metal. The important is,
1. MIG Weld Aluminum – Aluminium welding
Can you use MIG welding to weld Aluminum?
Yes. Here is some useful advice.
Welding aluminum through MIG welding is an easy and most commonly used type of welding.
This Gas Metal Arc Welding (GMAW) is commonly called ‘Aluminum Welding‘ and as well as it is also called ‘Metal Inert Gas (MIG)‘.
This type of welding has typically faster travel speeds and have higher deposition rates than the TIG welding
However, this type of welding needs a mechanical wire feeding system, so the welder may use a pool gun or push-pull gun to feed the wire, possible.
Important factors for Aluminum welding:
Preparation, Wire feeding, and a Shielding gas are playing a great role in welding with aluminum.
Before a welder starts MIG welding aluminum, the welder should get hold of a tank of shielded gas.
Trying a push-pull wire feed system or a spool gun to avoid this a hassle. This avoids aluminum filler, which tends to jam in the system.
When using a MIG welder, it is best to make welds in the horizontal and in the flat positions. It would be very easy to do fillet welds in lap joints than groove welds in the butt joints.
2. TIG Aluminum welding – Aluminium welding
TIG aluminum welding needs only basics.
Although many TIG welding is welded, aluminum is the frequency metal combined with the process. The popularity of aluminum in automotive applications has brought TIG welding to a new golden age.
Advantages of Aluminum TIG welding –
- A filler rod
- AC polarity for Aluminum and Magnesium
- Gives high Quality Welds
- Gives all position welding
- This type can be used in variety of metals
- Here, Fusion welding is possible
- No slag and no spatter
- High efficiency
Yes, that’s it we have covered important topics over Aluminum welding over TIG and MIG. Here are some other factors to know how other types of Aluminum is welded,
Welding a Cast Aluminum – Aluminium welding
When compared to weld the pure or alloyed aluminum, cast aluminum is quite a tuff task in welding. In this, as soon as the metal heats up, the impurities and air pockets start to bubble on the surface.
TIG welding is the best welding process for these types of jobs, as it gives greater control over the welds, as well as heat and speed.
Welding an Aluminum to steel
Aluminum is a soft, thin, and lightweight metal, whereas steel is quite a bit tougher, heavier, and thicker. So combining these two materials is a difficult task.
There are two ways used to weld Aluminum to steel.
The first is to insert bimetallic transition, which is considered to be a specially made piece of metal. It is specifically a small piece of metal, which contains two different metallic elements. One of these metals is Aluminum and the other will be welded (without using ARC welding) and is placed already and be combined with steel.
The Second step is to weld the steel to the other side of the insert.
But, be remember, aluminum doesn’t change its appearance as it heats up. It stays as silver and never has a red hot glow. The material should not be overheated. If it happens, it fall apart and the total work will be spoiled.
That’s it. We have covered an important topic under welding, which will be useful for all the welders.
