Welding is a fabrication process that is used for
fusing metal parts. Usually, welding is used for thermoplastics and metals
only. The importance of a good weld is simple and cannot be understated. It
largely determines the strength of the structure. Hence, it is imperative to
create a flawless weld. However, the most essential aspect of creating a
successful weld is the kind of welding rod you use. The welding rod known as
the welding electrode is easily available from welding electrodes suppliers.
How to Choose the
Right Welding Electrode?
These electrodes are the medium that is used for
fusing two different metals. Different types of welding rods can be availed
from Welding Electrodes Manufacturers in India. They are available
in different types and sizes, and their utility depends entirely on the
machinery you will be using to create the weld. To create a perfect weld, it is
crucial to choose the right electrode before you start welding process.
There are essentially three kinds of welding
electrodes that are manufactured by welding electrodes manufacturers and they are as
follows:
1.
Covered Rods
2.
Bare Welding Rods
3.
Tubular
The following are some factors that you can take
into consideration when selecting your welding rod:
1.
Properties of the
Base Metal
The chemical and physical properties of your base
metals should match or at least closely resemble the properties of the
electrode for your weld to be successful. You can refer to a metal composition
and an electrode chart for this purpose. This will make your task of selection
much more convenient.
2. Tensile
Strength
Other than matching the compositions of the base
metal and the electrode, you also need to match the metal's tensile strength
and compare it with the minimum value of the electrode's tensile strength. This
will help you avoid any cracks or other kinds of damage to the weld during the
process. If cracks appear in the weld, you will have to redo the entire
process. However, you’ll first have to clean up the cracked weld and restart.
Thus, not matching the tensile strength can prolong the process. The first two
numbers of the AWS classification define the tensile strength of the electrode.
3. Welding Current
Most electrodes come with the specification of the
kind of power sources they can be used with. This means that they can either be
used with DC or AC current. Some electrodes can be used with both types of
current. If you need to deeply penetrate the metal, you can go for electrodes
that can be used with AC currents. These electrodes also create a soft arc and
even clean metal sheets can be welded by using them.
Conclusion:
Apart from these, you need to determine the
thickness of the base metal and the welding position you will be using. These
factors will also influence the kind of welding electrode you should procure
from Welding Electrodes Suppliers in India. All of these
considerations will help you in creating the perfect desired weld.
