+G stud welding guns can be connected to the
BMK-8i ACCU stud welding device as standard guns. Using an adapter, the PH-
3 SRM stud welding gun can also be connected to it.
7.2.1 Stud welding with SRM® technology
The welding procedure recommended by SOYER® for operating the BMK-8i
ACCU is the patented SRM® welding procedure (patent no.: 10 2004 051 389) in
conjunction with the also newly developed HZ-1 universal stud with a plane end
face and centring tip (patent no.: 10 2006 016 553).
SRM® stands for stud welding in a radially symmetric magnetic field.
This innovative welding technology allows for welding in a ratio of 1:10 of the
sheet metal thickness to the stud diameter (up to now 1:4) with the use of ceramic
rings being no longer needed.
The various advantages of the SRM® procedure open up completely new possi-
ble applications in the entire stud welding area (for additional information, please
visit: www.srm-technology.de).
Functional principle
The advantages of the SRM® welding procedure are as follows:
• No annoying welding beads
• Welding under difficult conditions, now also without ceramic rings
• Reduced penetration in the sheet metal
• Less energy consumption and shorter welding time
• No welding spatters
The stud tip is placed
into contact with the
workpiece and raised.
The arc is triggered.
The ignited arc is guided
through a magnetic field
and melts both join parts
on their entire surface.
The stud is immersed in
the very flat penetration
zone and is inseparably
connected.
