TITLE(s): PLATER, HOT DIP (galvanizing) alternate titles: galvanizing dipper; pot runner
Tends equipment to coat iron and steel products with corrosion-resistant molten nonferrous metal:
Suspends metal objects, such as pails, shelving, nuts and bolts, and structural steel from conveyor
hooks or places them in wire baskets. Immerses objects in chemical solution to clean surface of
scale and foreign matter. Lowers objects into tank of ammonium chloride or other flux to protect
surface from oxidation and facilitate coating. Dips objects into tank of molten metal to coat
objects, using hoist or conveyor. Removes objects from tanks after specified time. Places objects,
such as nuts and bolts, in centrifuge and starts machine to cool objects and remove excessive
coating. Places objects, such as shelving and structural steel, into water tank or transfers them to
storage area to cool. Smooths coating, using wire brush and file. Inspects objects for even and
complete coating and returns defective objects for reprocessing. Scoops dross from tank, using
long-handled scoop, pours dross into molds, and weighs molded dross. Turns valves to regulate
