Ceramic ferrule for stud welding is used to protect the welding fluid from leakage because ceramic ferrule is high temperature resistant , so that welding ferrules can cool down and improve the welding quality. Prevent fire from welding gun and component welding place, prevent to damage the head of the gun, assist the forming of molten iron in the melting place, make the weld more beautiful, and use stud welding ceramic ferrule with the professional welding machine. Compared with the manual arc welding, the operation of ceramic ferrule for stud welding is simple and the skill is not high, and the damage of the arc and smoke to the workers is reduced.
Ceramic ferrule is important for stud welding 1)helps to shield the arc from the operator, 2)minimizes the atmosphere that the flux must purge, 3)forms the molten metal into the fillet, 4)the fillet vents allow weld gases to escape.
PF ceramic ferrule is designed for threaded stud, there are 7 sizes for choice: PF6, PF8, PF10, PF12, PF16, PF20, PF24.
PF ceramic ferrule’s main raw material is cordierite. And by molding, making the green body, calcining, etc. It is widely used for magnetic force floating railway engineer, building the bridge, building the railway, large power plant, plane depot that needs wide span.
SC choose low-expansion cordierite and other quality mixtures, and we also use higher temperature to burning the semi-product to confirm the final high quality to match the BS EN ISO13918:2008 standard(It can be used in all fields of the metal-working industry)
