6.2.1 Stud welding with SRM technology
®
The welding process recommended by SOYER
®
for operating the BMK-10i is the
patented SRM welding process (patent no.: 10 2004 051 389) in conjunction with the
also newly developed HZ-1 universal studs with flat front face and centring tip (patent
no.: 10 2006 016 553).
SRM means stud welding in a radially symmetrical magnetic field. This innovative weld
technology allows welds in a ratio of 1:10 of the sheet thickness to the stud diameter
(previously 1:4) where the use of ceramic rings can be dispensed with.
The versatile advantages of the SRM process provides completely new application
options in the entire stud welding sector (additional information available at
www.srm-technology.de ).
Functional principle
The stud tip touches the
workpiece and is lifted.
The arc is initiated. The ignited arc is guided
by a magnetic field and
melts both joint parts
fully. The stud immerses in the
very flat weld penetration
zone and is solidly
connected.
The advantages of the SRM welding process are:

No bothersome weld bead

Welding from constrained positions now also without ceramic ring

Reduced weld penetration in the plate

Lower energy consumption and reduced welding time

No welding spatter
