Arc stud welding of galvanized steel

Steel is a strong material that is commonly used in construction of roads, railways, infrastructure and buildings, and variety of other construction-related applications such as bolts, nails and screws. However, long exposure of steel to the atmosphere results in the formation of rust which will is...
