Welding Basics for Beginners
By Kenzie Thompson
Welding has been around for centuries, though not in the forms most
commonly used today. One of the first welding processes ever used was
known as forge welding. Forge welding attempts to join two metals through
a process of heating, and then pounding and striking. It’s what
blacksmiths did. But since then, there have been quite a few advancements
in the welding world. With these new methods and techniques, welding
has left the confines of industrial settings and can now be done practically
anywhere – even underwater or in outer space!
As you can guess from the history of welding, the ability to join two
or more pieces of metal together in a strong bond has been fundamental
in our advancements in all areas of life, from housing to transportation;
from manufacturing to repairs. Understanding welding basics can come
in handy at work, but it will just as often come in handy around the
house, in the workshop or on the farm. Because of this, welding is a
skill that almost anyone can benefit from, male or female, young or
old.
Why Weld? If you own any equipment or machinery that
is metal, welding will certainly serve as a useful skill. Some typical
goals of a welding job include:
• Fixing stress cracks • Reinforcing weak joints, and •
Cutting/shaping new parts and adapters from raw plating.
For chores like these, many welders rely on a process known as arc
welding. Arc welding is a method where during the welding process, an
electrical current jumps through an air gap (between a positively charged
electrode and a negatively charged steel
plate) and produces an enormous amount of heat. This heat is produced
at the end of a welding rod, and when it does, metal can be melted.
Well, it’s a little more complicated than that, but the concept
is the same.
Perhaps the most common and economical welding method used today is
AC (alternating current) arc welding. You can locate a simple AC welder
just about anywhere, such as your local farm store or home improvement
center. This welding process is ideal for most of your simple, routine
welding jobs. Therefore, AC arc welding is ideal for those of you just
starting out.
Minimize Your Risk While arc welding isn’t incredibly complicated,
there are a few risks and hazards that you should be aware of:
1. Exposure to radiation 2. Flying sparks (in the form of globs
of molten metal) 3. Electric Shock 4. Fumes 5. Damage to your
eyes, and 6. Burns
However, by wearing protective clothing and specialized welding helmets
and other gear, you can greatly reduce the inherent risks of welding.
Here are a few other tips to help keep you safe while arc welding:
• Make sure to work on a dry floor. Wear thick rubber shoes and
dry leather welding gloves. • Be sure to use insulated electrode
holders. • Check to make sure that your equipment is all
properly grounded. • Keep your work area properly ventilated to
avoid inhaling any potentially toxic fumes. • Be on the look out
for flying bits of melted metal. • Most importantly, be aware
of
any other people who are around you. If they aren’t wearing the
proper gear, then keep them away from your project.
This will get you started welding safely – one of the most important
things when learning a new craft.
