How To Spot A Good Weld
VS. A Bad Weld

In our modern civilization, it is
normal to see towering skyscrapers,
bridges, and other infrastructure
everywhere you look. 
Although welding may not be the first
thing that comes to your mind
whenever you see impressive
buildings, it is one of the most
important procedures in every
construction project.
Welding is a skill that anyone can
learn. There are several tools you
must learn to operate in order to do it
correctly. 
However, when you first start
learning how to weld, it can be
difficult to measure the quality of
your welding. Knowing how to spot a
good weld vs bad weld is necessary to
ensure the quality of a welding job.
What Does a Good Weld Look
Like?
Since there are different welding
processes, there are also different
varieties and ways to determine the
quality of each weld. That’s why it is
important to know the pros and cons
of each type of welding process.
Regardless of what process was used
for the welding job, quality and
strength are always the most
important criteria for good welds. If a
welding job is low-quality, it will not
be as strong.
Here are the different types of
welding and how to determine their
quality:
1. Stick Welding
Stick welding, most commonly
referred to as shielded metal arc
welding or SMAW, is one of the
easiest types of welding. 
It can work with different materials
such as alloy, stainless steel, iron,
copper, carbon steel, and even
aluminum.
A good stick weld has a straight and
uniform finish. The thickness of the
steel must not change, and there must
be no holes, drops of spatter, or
cracks. If there are visible spatters,
cracks, undercutting, or an
inconsistent width of the bead, it
means that you have a bad stick weld.
2. TIG Welding
TIG welding is a more complicated
procedure compared to stick welding
because it requires more skill and
accuracy to accomplish. 
TIG stands for tungsten inert gas
welding. This type of welding can be
used in different types of metals such
as aluminum, stainless steel, and
magnesium.
A good TIG welder can accomplish
the welding job perfectly, but an
inexperienced welder will leave
indistinct patterns on the steel.
A good TIG weld will appear neat and
flawless. There will be tiny welds
layered to create a pattern in the weld.
If your weld does not have any slag or
burnout, consider it a very good weld.
However, if you see a flat bead
without any distinct pattern, this
means that your TIG weld is poor.
You will have to re-do it because you
want to see clear patterns of layered
welds, no burnout, and no beads out
of place or misaligned.
3. MIG Welding
MIG welding is the most common
and easiest type of welding. It is the
type of welding usually done at home.
MIG stands for metal inert gas
because the welding gun gives power
to a wire electrode to act as the filler
metal that joins pieces of metal
together. It can be used on thin metals
such as mild steel and aluminum.
A good MIG welding must be straight
and uniform. There must be no
cracks, holes, or any type of breaking
in the weld. 
If your weld is too thin and has craters
on the bead, it means that the welding
job needs mending. Unlike TIG weld,
MIG weld does not have any
complicated patterns. All you need to
do is make sure that the welding
result is smooth and perfect.
Inconsistencies or cracks in the weld
are signs of a poor MIG welding job. If
there is no uniformity, the weld will
lack straightness; and if the bead
comes out too thin, the weld will not
have enough strength. All of which
are signs of bad welding.
4. Oxy Welding
This type of welding is not as
common as the others because it is
mostly used for the maintenance and
cutting of metal. It is often used for
welding intricate and soft metals such
as aluminum parts, bronze, and
copper.
The best way to spot a good Oxy
welding is to look for uniformity.
There must be no holes or signs of
melted metal. Poor Oxy welding will
result in holes and disarrayed
patterns.
Welding is one of the most important
parts of the construction process. It
can also be a useful skill if you want to
build or mend any metal projects.
There is certainly a lot to learn
including the different welding
processes. To determine a good vs.
bad weld, you must know the type of
metal that needs welding and the
welding process suitable for it.
