SRM stud welding - a new arc stud welding variant

摘要

In SRM stud welding (welding in a radial-symmetric magnetic field), a radial-symmetric magnetic field in combination with a shielding gas atmosphere protects the arc from external influence. This results in higher efficiency due to repeatable, high welding quality without arc blow problems. In practice, this means very even and defined partial melting of stud and sheet with considerably reduced energy input into the welded connection, reduced spatter formation and a small bead.
