Basic technical indexes of ceramic ferrules

Ceramic ferrules quality is very important to arc stud welding.also the welding strength is very important.normally the below information can decide the quality of ceramic ferrule 1, keep dry, not easy to absorb moisture,due to high temperature gasification, avoid water molecules  to let the weld gap have air hole and other defects. 2, moderate strength,ceramic ferrules for stud welding will not break or have large cracks after slight pressure...

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 metal vapor formed in the ceramic ferrule combustion chamber can escape from the incision exhaust. This prevents the...
