Basic Welding Health Hazards
Welding joins two metal pieces by the use of heat and with or without pressure apply.
Common Welding Processes are:
- Arc Welding Machine
- MIG Welding Machine
- TIG Welding Machine
- Argon Welding Machine
- Welding Rectifier
- Spot Welding Machine
- Plasma Cutting Machine
Health threats by Gases & Fumes
Mainly gases and fumes come from different way:
- Base material and filler material
- Coating and paints
- Shielding gases and their chemical reactions
- Process and different types of consumable used
- Contaminants in the atmosphere
- Wrong welding techniques
Contact of welding gases and fumes may have Short time impact and Long time impact.
Short time Hazards
- Irritate the eyes, nose, chest and respiratory tract.
- Cause coughing, wheezing, shortness of breath, bronchitis, pulmonary edema, and pneumonitis .
- Cause nausea, loss of appetite, vomiting, cramps, and slow digestion.
Long Time Hazards
? Welders may chance a variety of chronic lung problems, including: Bronchitis, asthma, pneumonia, emphysema, pneumoconiosis, decreased lung capacity, silicosis, and siderosis.
Other Health Hazards:
1. Heat exposure
- Skin burns and skin cancer
- May also increased metal stress & blood pressure, and further cause to heart problems, exhaustion, nervousness, and bad temper.
3. Eye damage– More than 5% eye injuries in industries and construction are associated with welding and cutting
- damage to retina
- damage to cornea, resulting in cataracts
- permanent eye damage
