    I am assuming you are concerned about the fumes produced #1 or maybe whether the galvanized coating should be removed prior to welding #2. #1 Galvanizing is usually a hot dipped process that contains zinc. Zinc can make you extremely ill and possibly kill you. Low doses give you zinc chills. Symptons feel like malaria. You can tell when you are being exposed to too much as it begins to smell sweet. Weld with plenty of ventilation. Upwind of air movement is best. #2 Zinc burns fiercely and vaporizes well below the temperature of the arc. It mixes with the weld creating a poor weld. Grinding off the zinc prior to welding greatly reduces this effect. Painting with a zinc coating while the pipe is still hot is recommended.
