Automotive Service Safety Welding
The fourth safety guidelines must always be followed when storing and transporting compressed gas tanks used for welding
Always keep valves closed when cylinders are empty or not in use. Remember to open them slowly when you start to use them.
STRSW equipment brings with it very different hazards like Fumes
Always use an approved welding respirator and a welding fume extractor. Keep the area ventilated from fumes.
STRSW equipment brings with it very different hazards like Sparks
Always wear PPE to prevent burns. Also, make sure the area is free of all flammable materials such as fuel, butane lighters, oil, and grease.
Burns
Burns to the skin and eyes due to exposure to arc radiation.
when using GTAW or TIG welders, you'll need to protect yourself against
Burns, Electric shock, fume exposure
Electric shock
Comes from power sourced for TIG welding and associated pieces of equipment such as add-on units that require electricity to operate.
The second type of welding used around the automotive shop environment is
Gas Metal Arc Welder (GMAW or MIG)
The third type of welding used around the automotive shop environment is
Gas Tungsten Arc Welder (GTAW or TIG)
Electrical arcing
Gold and silver rings can receive an arc and turn molten. This super-hot molten metal can literally burn fingers off. It's important to know that even necklaces and metal piercings (such as navel, nipple, nose, etc.) can draw an arc under the wrong circumstances.
Health effects from certain fumes
It can cause metal fume fever, stomach ulcers, kidney damage, and nervous system damage. Prolonged exposure to manganese fumes can cause Parkinson's-like symptoms.
The fifth safety guidelines must always be followed when storing and transporting compressed gas tanks used for welding
Light flames according to manufacturer instructions.
The third safety guidelines must always be followed when storing and transporting compressed gas tanks used for welding
Only use cylinders in areas with good ventilation and nothing around them that could burn or explode.
The first type of welding used around the automotive shop environment is
Oxygen/Acetylene Welder
The fourth type of welding used around the automotive shop environment is
Resistance Spot Welders
The first safety guidelines must always be followed when storing and transporting compressed gas tanks used for welding
Store cylinders in dry, ventilated areas on a fireproof floor, away from flammables or heat sources.
Eye injuries
The bright light generated by a welder can actually burn the retina. Always wear a welding helmet with a proper grade of filter plate in order to protect your eyes and face.
Sparks and spatter
The wire welder creates little fountains of flying sparks and small amounts of molten metal spatter than can burn an unprotected person and set small fires. You must protect your body with woolen clothing, a flame-proof apron, gloves, long sleeves, and tight-fitting pants that cover shoes.
Long-term exposure to welding fumes
This can cause lung damage and various types of cancer, including lung, larynx, and urinary tract.
Acute exposure to welding fumes and gases
This can result in eye, nose, and throat irritation, dizziness, and nausea. Workers who display these symptoms need to leave the work area immediately and seek fresh air and medical attention.
The second safety guidelines must always be followed when storing and transporting compressed gas tanks used for welding
When transporting cylinders, strap them to carts so they don't fall or bang into each other. Never drop or roll a cylinder.
STRSW equipment brings with it very different hazards like electric shock
You should use the same caution when around other electrical equipment. Ensure that the area around the welder stays dry. Never cool the tips by immersing them in water. Always inspect all dconnections and wires before each use.
Fume exposure
due to the open arcs which promote the formation of gaseous fumes as a result of the action of ultraviolet light and heat on atmospheric oxygen and nitrogen.
when using GMAW equipment. You'll need to protect yourself against
eye injuries, sparks and spatter, and electrical arcing.
Welding is classified into two groups
fusion (heat alone) or pressure (heat and pressure)
Gases such as helium, argon, and carbon dioxide displace oxygen
if in the air, it can lead to suffocation. This is a particular concern when welding in confined or enclosed spaces. Carbon monoxide gas can form, posing a serious asphyxiation hazard.
