The MPF arc-welded stud is threaded almost to the welding tip, the cross-section diameter is the wire size with which the MPF type weld stud is produced, so the weld bead will be about 3-4mm wider of the thread.
The maximum load borne by a MPF type weld pin is the same as any bolt made of material 4.8.
The MPF welding stud complete with ceramic ferrule is available with thread starting from M6 up to M20.
Through the use of the arc-stud welding machine, the arc-welded pin type MPF is welded in a long arc with a ferrule ceramic or welded in gas protection with appropriate limitations.
The production of the MPF arc-welded stud is carried out using the 4.8 iron, MPF pin in stainless steel A2-50 and stud welding type MPF in 1.4571.
