2.1Technology of tip ignition
The SOYER® Stud Welding Systems function according to the principle of
capacitor discharge with tip ignition in compliance with DVS leaflet 0903
(German Welding Society).
This system utilises the abrupt discharge of a capacitor battery to generate
electric arc energy.
Adjusting screw Stud holder
Workpiece
Stud
SZ.0001.E
The electric arc is initiated via the calibrated and close fit ignition tip on the
welding studs and the welding elements. The stud weld base and the opposite
surface of the workpieces is then melted slightly. The stud is automatically
immersed into the thin melted zone and/or the liquid weld bath. After the
immediate solidification of the material, an homogenous high-strength joint in
an extremely short welding time ranging only between 1-3 milliseconds (0.001-
0.003 sec.) is achieved.

Description of the Stud Welder Pistols
2.2Stud Welding Pistol PS-1
The SOYER® Stud Welding Pistol PS-1 is designed for a wide variety of
applications. The field-proven patented Positioning Pistol has a handy design,
is lightweight and is injection moulded of shock-proof, fully insulated plastic.
With this pistol the welding stud can be positioned exactly on a specific part of
the workpiece without requiring any auxiliary aids. Templates are not required.
Before welding the stud position has to be marked or centred slightly. The
calibrated ignition tip is then positioned on the marked point. When the pistol is
operated, the stud is mechanically lifted. A necessary air gap is created
between the tip and the workpiece. The stud is then mechanically moved to
the marked point and is welded with electric arc ignition as soon as the marked
point is reached.
R
The pistol guide is protected by rubber bellows especially against weld spatters
and dirt.
A special spring pressure display with scale shows the spring pressure for the
respective welding task and enables the reproducibility of welding joints, if
necessary.

Quality Control
6Quality Control
6.1General information
The DVS directive 0905, part 2 of April 1979 is valid with regard to ensuring the
quality of stud welded joints. The tests described in this section have been
written in a simplified form on the basis of this directive. They refer to work
tests which are carried out and controlled by the User prior to and during
welding works.
Heinz Soyer Bolzenschweißtechnik GmbH is a member of the Deutscher
Verband für Schweißtechnik e.V. (DVS) (German Welding Society), Munich.
6.2Demands on the company
R
The company must appoint a responsible welding supervisor and employ
appropriately qualified operating personnel for stud welding (see DVS Directive
0905, part 2, section 4).
6.3Proof of qualification
In the case of components which are subject to documentation requirements
and/or stud welding works which are subject to acceptance in compliance with
DIN 4100, DIN 4113, the manufacturing company must submit proof of
competence or a qualification certificate (see DVS Directive 0905, part 2,
sections 4.1 and 4.2). The competence qualification is applicable in particular
for fastening constructions concerning safety regulations. If the Stud Welder is
used in the construction industry, only permissible base and stud materials
(see e.g. DIN 4100, clause 2.1, registration license for stainless steel ifBT; DIN
4113, part 2) may be applied.
6.4Type and scope of testing
If the SOYER stud welding system is handled in compliance with regulations
and the proper materials are selected, the welded joint strength (welding zone)
will always be higher than that of the stud or base material. In practical
operation, the following work tests are carried out:
6-24
• Normal work test (see DVS Directive 0905, part 2, section 5.1.2)
• Simplified work test (see DVS Directive 0905, part 2, section 5.1.2)
R
6.4.1 Normal work test
Quality Control
Normal work tests are generally to be implemented and controlled by the
Operator prior to carrying out welding works at a construction and after a
certain number of welds. The number of welds after which a normal work test
is necessary is agreed with the customer.
The normal work test is restricted to the stud diameters, base material and
stud welder type used. It includes the following tests:
• Visual check (all samples)
• Tension test (at least 3 samples)
• Bending test (at least 3 samples)
In case of doubt, the scope of testing should be extended in compliance with
the DVS Directive 0905, part 2, section 5.1.1).
6.4.2 Simplified work test
Simplified work tests serve to control the correct stud welder setting and
functioning of the equipment. They are carried out before starting any shift or
after any interruption lasting for several hours.
The simplified work test includes:
• Visual check (all samples)
• Bending test (all samples)
6.5Implementation of sample taking
6.5.1 Production of samples
The studs for the work test are welded to a sheet metal the minimum size of
which is 700 mm x 200 mm. The same welding positions and distances to the
borders shall be adhered to as on the construction part. Identical parts to
those to be used in later production should be used for the tests provided this
is possible and economically justifiable.
6.5.2 Visual check
The visual check serves as a rough control to detect any possible major faults.
The uniformity of the welding is assessed. Tension or bending tests must be
carried out in case of doubt.

Quality Control
6.5.3 Tension test
R
The tension test serves to test the metallic bond between the stud and the
base material. At least 3 studs are welded and then axially loaded by means of
an appropriate tensile testing machine unitl they break. If the Customer
demands that a certain percentage of the welded studs should be tested with
a predefined test load in production, a tensile testing machine with load unit
display must be used.
If the stud breaks beyond the welding zone, the sample test is regarded as
successful. If the stud breaks within the welding zone, the fracture must be
examined. The unwelded surface must not exceed a maximum of 20% of the
welding surface. In cases of doubt, the breaking load is to be examined in
accordance with DIN 267, part 3.
If the number of faulty studs in any one random test exceeds the acceptance
number in compliance with DIN 267, part 5, according to AQL 4, it is
necessary to determine the reason for the faults. In such a case it is necessary
to modify the setting values and then repeat the test.
6.5.4 Bending test
The bending test is a simple work test and is designed to roughly control the
setting values selected. An undefined tension, pressure and bending is exerted
on the welding zone. At least 3 studs are welded and bent by 30° using an
attached laterally ground tube. The test is regarded as successful if no tear or
fracture is detected in the welding zone. The acceptance figure in compliance
with DIN 267, part 5, according to AQL 4 must be observed. If in one test
batch the number of faulty parts exceeds the acceptance figure AQL 4 (see
DIN 267), the reason for the faults must be determined and the complete test
repeated.

7.Maintenance
7.1Stud Welding Pistols
The Stud Welding Pistols have been constructed in such a way to require only
a minimum of maintenance. The parts of the Stud Welding Pistol which may
get damaged by weld spatters, such as stud holder and pistol feet and/or
centering support tube should, however, be kept clean. The stud holder and
pistol feet are wear-and-tear parts and should be replaced if they display any
signs of wear and tear.
