arc welding safety
Arc Welding Safety
  • Welding can be safe when sufficient measures are taken to protect yourself and others from potential hazards
  • Students should read and understand the following before welding:
    • Warning Labels
    • Material Safety Data Sheets (MSDS)
  • Students should also be familiar with the following information
    • ‘Safety in Welding, Cutting, and Allied Processes’ (ANSI Z49.1)
    • Lincoln Electric’s ‘Arc Welding Safety’ (E205)
warning labels
Warning Labels
  • Understand and follow all warning labels found:
    • On welding equipment
    • With all consumable packaging
    • Within instruction manuals
material safety data sheets
Material Safety Data Sheets
  • Material Safety Data Sheets (MSDS) are:
    • Required by law and OSHA
    • Created by the manufacturer of a product per OSHA guidelines
    • Designed to inform users
    • Shipped with every box of Lincoln Electric consumable product
    • Available free online at:

arc welding safety1
Arc Welding Safety
  • Protect yourself and others from potential hazards including:
    • Fumes and Gases
    • Electric Shock
    • Arc Rays
    • Fire and Explosion Hazards
    • Noise
    • Hot objects
fumes and gases
Fumes and gases can be hazardous to your health

Keep your head out of the fumes

Use enough ventilation, exhaust at the arc, or both, to keep fumes and gases from your breathing zone and the general area

See product labeling and MSDS for ventilation and respirator requirements

Fumes and Gases
electric shock
Electric Shock
  • Electric shock can kill
  • Do not touch live electrical parts
    • Primary Voltage –230, 460 volt input power
    • Secondary Voltage – 6 to 100 volts for welding
  • Insulate yourself from work and ground
  • Follow all warnings on welding equipment

Do not make repairs yourself, alert your instructor immediately!

arc rays
Arc rays can injure eyes and burn skin

The welding arc is brighter than the sun

Precaution must be taken to protect your eyes and skin from UV radiation

Wear correct eye and body protection

Arc Rays
fire and explosion hazards
Welding sparks can cause fires and explosions

Sparks and spatter from the welding arc can spray up to 35 feet from your work

Flammable materials should be removed from the welding area or shielded from sparks and spatter

Have a fire extinguisher ready

Inspect area for fires 30 minutes after welding

Fire and Explosion Hazards
noise
Noise
  • Loud noises can damage your hearing
  • Keep loud noises at a safe level by using proper hearing protection such as:
    • Ear plugs
    • Ear muffs
protective clothing
Protective Clothing

Welders must wear protective clothing for

    • Protection from sparks, spatter and UV radiation
    • Insulation from electric shock
  • Protective clothing includes …
    • Fire-proof clothing without rolled sleeves, cuffs or frays
    • Work boots
    • Welding gloves, jackets, bibs, and fire-proof pants
    • Welding cap, helmet and safety glasses
    • Ear protection – ear plugs and muffs
what are the responsibilities of a welder
What are the Responsibilities of a Welder?
  • Welders have many areas of important responsibilities
  • These relate to:
    • Arc Welding Safety
    • Knowledge – Content
    • Attitude – Reactions
    • Skills – Performance
    • Work Habits – Daily Functions

Always keep safety in mind when welding

Arc Welding Safety
  • A welder MUST always follow safe work practices:
    • Students should read and understand the following before welding:
      • Warning Labels
      • Material Safety Data Sheets (MSDS)
    • Students should also be familiar with the following information
      • ‘Safety in Welding, Cutting, and Allied Processes’ (ANSI Z49.1)
      • Lincoln Electric’s ‘Arc Welding Safety’ (E205)
knowledge content
Knowledge - Content
  • Welding can teach you about….
    • Science when applying metallurgy, chemistry, electricity, etc.
    • Math when calculating angles, joint design, and weld size
    • English when communicating and interpreting drawings, codes, and procedures
    • Technical areas when performing the actual welding applications

How much science and math went into the development of this bike?

attitude
Attitude
  • The best welders demonstrate a can-do attitude when performing welding processes
  • This means being able to…
    • Work as a team member
    • Communicate ideas to others
    • Listen to opinions of others
