What safety procedures should a person follow when welding?
Welding Safety Precautions
- Welding helmets with side-shields. Welding helmets protect you from UV radiation, particles, debris, hot slag and chemical burns.
- Respirators. Respirators protect you from fumes and oxides that the welding process creates.
- Fire resistant clothing.
- Ear protection.
- Boots and gloves.
What are the procedure in carrying out welding?
How to weld (Arc)
- Step 1: Safety.
- Step 2: Gather necessary equipment.
- Step 3: Clean your metal.
- Step 4: Cut your metal.
- Step 5: Set up your work-piece.
- Step 6: Turn on the welder and adjust the settings.
- Step 7: Tack-weld the work-piece.
- Step 8: Fill in the remaining areas with ‘bead’ welds.
What are the 4 welding processes?
There are four main types of welding. MIG – Gas Metal Arc Welding (GMAW), TIG – Gas Tungsten Arc Welding (GTAW), Stick – Shielded Metal Arc Welding (SMAW) and Flux-cored – Flux-cored Arc Welding (FCAW). We dive deeper into each type of welding here.
What are the 5 essentials for proper welding procedures?

- 3) CORRECT ARC LENGTH or VOLTAGE.
- 4) CORRECT TRAVEL SPEED.
- 5) CORRECT ELECTRODE ANGLE.
- 8 FACTORS to consider in selecting arc welding electrodes.
What are the top 10 safety rules when welding?
10 Arc Welding Safety Tips
- Tip #1 – Read the owner’s manual, warning labels and relevant codes.
- Tip #2 – Avoid electric shock.
- Tip #3 – Shield eyes and skin from UV light.
- Tip #4 – Avoid burns.
- Tip #5 – Maintain your equipment.
- Tip #6 – Avoid breathing fumes.
- Tip #7 – Protect your eyes and ears.
- Tip #8 – Wear the right gear.
Why can’t you look at a welding flame?
A flash burn occurs when you are exposed to bright ultraviolet (UV) light. It can be caused by all types of UV light, but welding torches are the most common source. That’s why it’s sometimes called ‘welder’s flash’ or ‘arc eye’. Flash burns are like sunburn in the eye and can affect both your eyes.
Why is it important to follow the correct procedure in welding?
Welding fumes cause some illnesses such as lung cancer, heart disease, kidney damage, stomach disease, motor and neurological problems. Some specific materials may require respirators when welding that’s why it’s important to provide employee safety training.
What is 5S in welding?
5S is a system to reduction waste, productivity optimization and quality through maintaining and organizing work-place [3]. The 5S concept consists of Sort (seiri), Set in Order (seiton), Shine (seiso), Standardise (seiketsu) and Sustain (shitsuke). 5S is generally applied to medium to large scale industries.
What is the easiest welding method?
MIG Welding (Beginner) As a semi-automatic or automatic process, gas metal arc welding (GMAW or MIG), is the easiest to learn.
What are the 5 essentials of welding and why they are important?
WELDING PROCEDURES 1) CORRECT ELECTRODE SIZE. 2) CORRECT CURRENT. 3) CORRECT ARC LENGTH or VOLTAGE. 4) CORRECT TRAVEL SPEED.
Should tack welds be removed?
Tack welds used to secure alignment shall either be removed completely when they have served their purpose, or their stopping and starting ends shall be properly prepared by grinding or other suitable means so that they may be satisfactorily incorporated into the final weld.
What do you need to know about welding procedures?
Contact Us . Open in a New Window. Welding-procedures convey the required information to the workers performing welding operations. They also assist in controlling workmanship and consistency . Welding Procedure Specifications (WPS) are detailed welding work instructions .
What are the General Welding guidelines for code welds?
All ASME Section IX variables are covered in the Welding Procedure Specifications (WPSs). The welder shall follow the instructions in the WPS when making Code welds. In addition to the instructions in the WPSs, the following portion of the General Welding Guidelines shall be followed during all welding. Joints
What are the essential variables in a welding procedure?
Therefore, a change in any of the essentials will invalidate the welding procedure and will require a new approval test to be carried out. The essential variables are detailed in the relevant specification but include material type, welding process, thickness range and sometimes welding position.
Can you buy a prequalified Welding Procedure Specification?
A prequalified welding procedure specification is only allowed by certain welding codes. And a prequalified WPS is not a published document you can buy, it still must be developed. If you buy a copy of AWS D1.1 Structural Welding Code (Steel) expecting to find prequalified welding procedures you are in for a big surprise.
