• 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)

Arc Welding SafetyArc 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 GasesFumes 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

Electric ShockElectric 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 RaysArc 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 HazardsFire 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

NoiseNoise

• 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 ClothingProtective 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

16

Arc Welding SafetyArc 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

Knowledge - ContentKnowledge - 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

AttitudeAttitude

• 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/PerformanceSkills/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 FunctionsWork 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
