5. Arc welding is most commonly used to join two pieces of metal
What is Arc Welding?
Arc welding is most commonly used to join two pieces of metal
The welder creates an electric arc that melts the base metals and filler metal (consumable) together so that they all fuse into one solid piece of metal
Steel Pipe – Tack Welded
Final weld after several beads are made
Root Pass or “Stringer Bead”

6. Basic Steps of Arc Welding
Prepare the base materials: remove paint and rust
Choose the right welding process
Choose the right filler material
Assess and comply with safety requirements
Use proper welding techniques and be sure to protect the molten puddle from contaminants in the air
Inspect the weld

7. 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).

8. 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

9. 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

10. 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!

11. 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

12. 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

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

14. 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
