the use of ceramic ferrules for stud welding

For the studs with diameters exceeding 10 mm, ceramic ferrules are the most common protection. Its essential role is: (1) it can focus arc on the workpiece surface, stabilize arc, reduce heat loss and reduce cooling rate and avoid arc diverge and blow. (2) because ceramic ferrule for stud welding allows high temperature, the […]
