1. Welding Safety SECTION OVERVIEW:
The next few slides identify safety requirements when welding.
TEACHER NOTES:
Slides 15-27: Bulleted information on topical areas is provided to lead class discussion on important areas of safety in the welding environment.
Use this time to discuss OSHA (Occupational Safety & Health Administration)
OSHA -
Regulation 1910 – Occupational Safety and Health Standards for general industry
Tell the students where all the information listed on the following slides can be found.
MSDS – Quick Links: MSDS or call
See slide 20 for additional website links
See Facilitator’s Guide for more information on welding hazards such as Fumes and Gases and Electrical Shock.
For a free DVD on Welding Safely, submit the order form found in the back of the Lesson Plan Facilitator’s Guide (shipping and handling charges will apply).

2. 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)

3. Understand and follow all warning labels found:
On welding equipment
With all consumable packaging
Within instruction manuals

4. 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:

7. Protect yourself and others from potential hazards including:
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

8. 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

9. Do not make repairs yourself, alert your instructor immediately!
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!

10. 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

11. 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

12. Loud noises can damage your hearing
Keep loud noises at a safe level by using proper hearing protection such as:
Ear plugs
Ear muffs

13. 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

14. Welder Responsibilities
SECTION OVERVIEW:
The next few slides reference information extracted from the ‘Guide for the Training and Qualification of Welding Personnel, Entry Level Welder’ (AWS EG 2.0) booklet to help students understand about the responsibilities of a welder.
TEACHER NOTES:
Slides 49-55: These slides include bulleted information on topical areas to lead class discussion on the importance of each area when conducting the welding processes.
‘Guide for the Training and Qualification of Welding Personnel, Entry Level Welder’ (AWS EG 2.0) book available through the AWS. (
For more information on Lincoln Electric's Welding Educator’s Workshop see the Technical Training Guide (ED122):

15. 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

16. A welder MUST always follow safe work practices:
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)

17. Welding can teach you about….
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?

18. 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
Promote a positive attitude
Provide solutions to problems
Take pride in workmanship
These welders work together to inspect a weld.

19. Skills/Performance
A welder must demonstrate technical skills when performing welding processes
A welder must know how to:
Use hand tools and materials, to operate equipment in a safe, accurate, and consistent manner
Acquire and evaluate information needed for problem solving
Complete quality work
Maintain equipment
There is no room for poor workmanship in NASCAR

20. Work Habits/Daily Functions
A welder must practice good working habits when performing welding processes
This means being able to …
Follow detailed verbal and written instructions
Maintain workspace, equipment, and tool cleanliness
Correctly fill out, maintain and submit time cards, work assignment cards, and other records as required
Follow safe working practices
