What are AC welding and DC welding?
When you are just stepping into the world of welding, you can feel quite overwhelmed by the sheer amount of information there is to learn. There are tons of terminologies and infinite variables. From knowing how to set up your equipment to knowing different types of metals, there are several different things that you should learn about. You also need to learn about the variations that might be made in thickness, amperage, and filler material. For instance, you might notice that your welding machine settings offer two options - AC (Alternate Current) welding and DC (Direct Current) welding. Whether you opt for flux-cored welding for which flux-cored wire can be procured from flux cored wire manufacturer in India or solid-wired welding, it is important to understand the major differences between AC and DC welding.
AC welding v/s DC welding
Apart
from the kind of current you choose, the choice of your electrodes will also
have a major impact on your welding performance. So make sure to procure
superior quality flux cored wire from Flux Cored Wire Manufacturers.
It is important to note that one is not superior to the other. You just need to
understand which one works better in different situations. The choice you make
will depend on a variety of factors, which are discussed in the following
sections of the article.
AC Welding
When
it comes to AC electricity, the direction of the flow of electrons switches up
around 120 times each second. Given that the current is always alternating,
this one is rightfully called the alternating current. However, when it comes
to welding, AC is usually considered to be inferior and DC is the go-to choice
for most people.
However,
it should be noted that this is not always the case. AC welders are much more
inexpensive in comparison to DC welders and hence, they are much more suitable
for beginners. Also if you plan on welding magnetic materials then opting was
AC welding would be sensible. Alternating current helps in creating a steadier
arc when it comes to magnetic materials and this helps in reducing the arc blow
that you might experience if you use the DC welder. You can also shield
yourself from the splatter by making use of DIFFCOR glass procured from Diffcor manufacturer.
DC Welding
DC
is an abbreviation for direct current as the electrons flow only in a single
direction. This type of current is usually found in low-voltage devices and
batteries. The absence of zero-amperage, which is present in AC welding, helps
in creating a much more stable arc overall. DC welders are much easier to
control and help in creating cleaner and smoother welds. It also produces less
splatter. If you are a beginner then it is advisable to opt for DC welding as
there is a shorter learning curve and this allows you to produce attractive
welds.
It
should be remembered, however, that DC welding is not the best choice since you
will get arc blow. You can also make use of diffcor purchased from diffcor suppliers to
shield your weld from environmental factors. If you plan on working with
magnetic materials, settling for AC welding would be advisable.
