Welding Badge By Christian Fisher with Mr. Mitchell
Hazards There are a couple hazards when welding - Bright light caused by the arc - The heat caused by the arc as you weld - The potential for shock
Bright light hazard The light caused by striking and arc can severely damage your eyes over time. To prevent this from happing you must wear a mask that covers your face and eyes.
Heat hazards As you weld splatter from the welding rod can burn your skin Metal holds heat for a long time and the hot metal can burn you well after you have finished welding
Shock Hazards Welding is accomplished using high amperage electricity. IF you do not have a good ground source the electricity may shock you or worse Electricity travels the path of least resistance so while welding you must take precautions you are not that path
First Aid Electric shock Call 911 Look first. Don't touch. The person may still be in contact with the electrical source. Touching the person may pass the current through you. Turn off the source of electricity, if possible. If not, move the source away from you and the person, using a dry, no conducting object made of cardboard, plastic or wood
First Aid Check for signs of circulation (breathing, coughing or movement). If absent, begin cardiopulmonary resuscitation (CPR) immediately. Prevent shock. Lay the person down and, if possible, position the head slightly lower than
First Aid Burn Cool the burn. Hold the burned area under cool (not cold) running water for 10 or 15 minutes or until the pain subsides. If this is impractical, immerse the burn in cool water or cool it with cold compresses. Cooling the burn reduces swelling by conducting heat away from the skin. Don't put ice on the burn. Cover the burn with a sterile gauze bandage. Don't use fluffy cotton, or other material that may get lint in the wound. Wrap the gauze loosely to avoid putting pressure on burned skin.
First Aid Bandaging keeps air off the burn, reduces pain and protects blistered skin. Take an over-the- counter pain reliever. These include aspirin, ibuprofen (Advil, Motrin, others), naproxen (Aleve) or acetaminophen (Tylenol, others).
MSDS A Material Safety Data Sheet (MSDS) or internationally known as Safety Data Sheet (SDS) (also known as PSDS, Product Safety Data Sheet) is an important component of product stewardship and workplace safety. It is intended to provide workers and emergency personnel with procedures for handling or working with that substance in a safe manner.

Welding definitions Welding -Join together two pieces of metal by heating the surfaces to the point of melting with a electric arc. Electrode - An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit. Slag- is a partially vitreous by-product of smelting ore to separate the metal fraction from the unwanted fraction Oxidation- A reaction in which the atoms in an element lose electrons and the valence of the element is correspondingly increased. (otherwise known as rust)

In some cases, an associate's or bachelor's degree could be needed
American welding society The American Welding Society (AWS) is a nonprofit organization dedicated to advancing the science technology, and application of welding and allied joining and cutting processes, including brazing and soldering.
