3 Description of welding equipment
3.1 Description
The BMK-12i stud welding inverter has been designed for mobile use. As a result of intensive
development work in the area of inverter technology, the SOYER®BMK-12i defines a completely new
equipment class. The equipment operates on the basis of a compact inverter source of electricity and
provides constant welding currents up to 800 A with extremely short welding periods. Here, the
rectified mains voltage is converted into a high-frequency voltage with a frequency of 100 kHz via an
inverter on a MOSFET basis. The electrical current is transferred via a high-frequency transformer and
is rectified on the output side. As a result of the high control rate in connection with the integrated SRM
welding procedure of the BMK-12i, the reproducibility of the weld is increased and the quality
significantly improved.
The equipment offers the possibility to store the parameters for different welding tasks as welding
programs and to call them up again at any time. In order to simplify the operation, programs for
different stud diameters can be saved. This enables a simple and rapid switching between different
welding tasks.
The equipment comprises four push-buttons as well as a full graphic display with intuitive menu
navigation on its front panel. The settings are made via the push-buttons. The operating status during
the welding process is indicated on the display.
The following stud welding procedures are supported by the equipment:
●Stud welding in a radially symmetric magnetic field (SRM)
●Drawn arc (DA) stud welding with inert gas
●Short-cycle (SC) drawn arc stud welding (without inert gas and without ceramic ring)
The PH-9 SRM stud welding gun with control cable and SRM inert gas equipment should be
connected to the BMK-12i stud welding inverter as standard gun. This operating manual exclusively
describes the BMK-12i stud welding inverter. Information regarding the stud welding guns to be used
as well as their setting can be obtained from the respective operating manuals of the stud welding
guns.
3.2 Stud welding in a radially symmetric magnetic field (SRM Technology)
For operating the BMK-12i stud welding inverter, we recommend using the patented SRM stud
welding process (patent no. 10 2004 051 389) in conjunction with the newly developed HZ-1 universal
weld stud featuring a plane end face and centring tip (patent no. 10 2006 016 553). This innovative
welding technique enables welds at a ratio of 1:10 from the sheet thickness to the stud diameter
(previously 1:4). Furthermore there is no need to use ceramic rings during this process. The numerous
advantages delivered by the SRM procedure offer completely new potential applications in the entire
field of stud welding technology (for additional information, please refer to www.hz-1.com).
Further benefits of SRM welding include:
●No disturbing weld bead
●No ceramic ferrule required even in constrained positions (out-of-position welding)
●Reduced penetration in the sheet
●Less energy consumption and shorter welding time
●No weld spatters

15
The stud comes into contact
with the workpiece and is
raised. The arc is triggered.
The arc is guided through the
spiral-shaped magnetic field
and fully melts both join parts.
The stud immerses into the
very flat penetration zone and
is inseparably connected.
The above illustration shows the radially symmetric magnetic field stud welding process (SRM).
With this welding process, we recommend using the following inert gases:
gas mixture containing 82% of Argon and 18% of CO2or gas mixture containing 90% of Argon and
10% of CO2.
3.2.1 Drawn arc stud welding technology using shielding gas
With this method, a gas mixture containing 82% of Argon and e.g. 18% of CO2(e.g. Corgon®18*) is used
as auxiliary aid. This shielding gas protects the welding point from the atmosphere and simultaneously
supports the weld pool. Moreover, it ensures a concave fillet weld upset formation with a blank metallic
surface, thus reducing the risk of corrosion and obtaining an improved dynamic behaviour of the
welded joint.
An accurate bulging, to scale or in a calibrated or reproducible type, is not possible when welding with
shielding gas without using any auxiliary aid. Stud welding with shielding gas can be carried out at
much shorter intervals as no ceramic ferrules have to be fitted and removed in each welding process.
