from Ekeeda then I’ll talk about shielded metal arc welding it would be
the arc which is shielded with some flux or with some slag with enhance your
welding process so we’ll go into detail in this video so in shielded metal arc
welding the arc itself is shielded with some flux material it is coated and
coated properly so that it should not get welded away or should not let take
away then I come to power supply cables as it is an arc welding power supply
cables and additional stuff which is required for welding basically arc
welding is used for shielded metal arc welding so it is one of the oldest
method of doing welding strong waves can be formed as well as shielding can be
done at a faster rate and at a very proper rate if it is done properly so
these are some of the advantage of shielded metal arc welding and as I have
told you the arc is shielded like electrode is shielded with some flux
because the name is shielded metal arc welding so in this diagram we can see
that there is your workpiece on that slag is there shielding is there
shielding of what your electrode because of that shielding gas is being produced
around your weld pool so you have to provide some input power supply because
of that there are cables which are used so in this diagram you can also see a
slag layer which is there there is a protective layer of gas the arc is used
which is shielded and there is a power supply also filler metal can be used or
not used according to the need so its composition should be such that it
should get mixed with your base metal so it should have the same composition your
electrode should have the coating of oxide flux slag etc so that during the
welding process when the arc is that is a power supply is used it is
fully welded so in this photo you can see that the person who is doing the
welding is wearing some kind of protection that apart but the welding is
done which is not shielded metal arc welding electrode is it which is coated
as well as you can additionally use a filler metal so the basic applications
where shielded metal arc welding can be used are you can use it in cast iron
steels etcetera but it is not used in alloys coppers tins these whole methods
so this is shielded metal arc welding thank you for watching this video stay
