The joining process of two metal elements through melting is known as welding. It is not an easy job. It is pretty much challenging.

However, when it is the matter of welding any light thing, for example, Al welding, then you will face more challenge. For ensuring a strong bond, you need more accuracy.

Before giving your Aluminum to stick weld, first, take some knowledge about the stick welding.

Stick welding: SMAW is known as stick welding. It is a standard and widely used process. With electrode and electric power, it can join various materials. The core contains solid rod metal. Metal powders and mineral compounds enclose it.

The initial task of the electrode is covering the arc and protecting the hot item from the environment.

The shield helps to save from the composition of the chemical. The structure of covering depends on electrode category.

The using facilities of stick welding

o It is a versatile process.
o It can be operated in any place.
o Perfect for both outdoor and indoor performance.
o No requirement of gas, water hose.
o It is a handy object. It is not too much responsive to air.
o Maximum our daily use metal can be weld through it.

For welding Aluminum, stick welding is a good option. Though stick welding has some limitation, which described later in the article for aluminum, it is doubtlessly perfect.

Required materials for stick welding:


o An electrode (tungsten) and inert gas.
o The inert gas for shielding the welding area.
o TIG is expensive but gives the best accuracy.
o It is most suitable for welding Aluminum.

Filler Rod :

o The filler rod is required for bonding the two materials together.
o Unclean filler rod must be avoided.
o Otherwise, it will hamper the welding.
o Make a weak weld.
o Its size should be the same size as the electrode.

Argon gas:

o The role of Argon gas for shielding process.
o In good pure argon has 3 % He.
o It makes the arc stable.

Protective cloth:

o Use the shirt with long sleeve.
o The fabric should be thicker.
o Protect UV radiation.
o Cuffed pants can catch fire.
o So make sure that there are no cuffs on your pants.
o Use CVC (cheap value cotton or 100% cotton) shirts

Take protective or safety tools :

o For saving use heavy helmet
o A couple of gloves
o Gas musk etc.

Those will help you to protect from burning, light, radiation, and others unwanted situation. After managing all welding items, your next work is given a good set up of the working place.

Aluminum cleaning:

o If Aluminum is coated with oxide, it should be removed.
o Because it will be the reason for the high temperature.
o By grinding or by brushing it can be cleaned.
o Use water to clean. Let it dry.
o Rub it with wool

Filler rod cleaning:

o The dirty rod can pollute welding.
o Use a cleaning pad.
o Clean it properly.
o Make it dirt free.

Tight workpiece:

o The unfitted joint can be costly.
o Before starting, fit the clamp properly.

Preheating: Preheating can give you benefit. It makes the aluminum to a smooth weld.

When the room temperature is hot, welding becomes easy. A propane torch can help to make heat. Target temperature should be 300 F to 400 F.

Working Atmosphere: the location of work have to Ventilated, safe easy assessable.

Now let’s discuss the motion of welding:

Brazing torch with the hand:

o Pull the tip at the correct angle.
o Pulling it far can cause difficult welding.
o 90-degree angle filler:
o Keep it at 90-degree angle for torching tip.
o Push the torch instead of dragging

Torch moving:

o Try to move it correctly.
o Keep practicing to be an expert.

Button pressing:

o The simple process, there is a button to utilize it for pressing on the torch.
o It helps to electric arc forming.

Using foot pedal:

o If there is no button, use the food pedal for creating the arc.
o Check amp if it is not starting.
