Welding On Galvanized Metals One of the most significant health hazards in the welding process is the generation of fumes and gasses. Do you weld on galvanized metals? Zinc is the coating used on galvanized metals, and when you heat the metal, it produces vaporized metal droplets which are called fumes. This is the smoky haze which consists of fine particles of metals or silicates. When you breathe these fumes, they may work deeply into your lungs. The typical effect of breathing zinc fumes is metal fume fever. One or two hours or more after welding-without proper personal protection-you may experience severe...

What You Need To Know About Welding & Cutting Protecting yourself when performing welding operations depends on your understanding of the hazards involved and the proper way to control them. Control of welding hazards includes avoiding eye injury, respiratory protection, ventilation of the work area, protective clothing and having safe equipment to use. Eye hazards include exposure to ultraviolet and infrared light. Welders and their helpers should wear filter glasses with shades ranging from 2 to 14, depending on the type of welding being done, to protect their eyes. Unless a welding arc is behind a screen, not only the welder, but...

Warning: Welding May be Hazardous to your Health You’ve heard the expression, “You are what you eat.” Well, with welding, one could say you are what you breathe. Welding smoke is a complex mixture of very small, condensed solids (fumes) and gases. The base and filler metals, fluxes, coatings, and shielding gases all contribute. Even chemical changes to the surrounding atmosphere from the intense radiation and heat can add to the mix. The effects of welding smoke on a person will depend on the particular components of the smoke and how much of it the welder breathes. Some effects may occur shortly after...
