Heavy Duty Ferrules

Heavy Duty Ferrules

The ferrule helps to shield the arc from the operator, it minimizes the atmosphere that the flux must purge, the ferrule helps form the molten metal into the fillet, while allowing the fillet vents allow weld gases to escape. Ferrules are disposable items and as disposable items they are mass manufactured quickly and inexpensively. Ferrules are cast in a mold out of a low grade moldable ceramic, then taken out of the mold and dried. Due to this manufacturing method, ferrule tolerances can be greater than machining or other manufacturing processes. Therefore, it is not recommended to fixture off of a ferrule when exact location is required.
