stud welding ferrule is a kind of ring-shaped ceramic molten pool which is used to protect the molten metal after the welding nail and the base material are melted by discharge. Working principle: stud welding ferrule use the high temperature resistance of ceramics to protect the welding melt from leaking, […]

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 […]
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 […]
Ceramic ferrule for stud welding of main chemical composition is 2MgO*2Al2O3*5SiO2, adhere to control the content of impurities with the raw materials of high purity, pure and stable chemical composition in the process of sintering or calcined materials, bring customers more added value.The dry pressing and sintering of 1300 degrees […]
