STUDWELDING EQUIPMENT AND SYSTEMS

CD controllers use advanced inverter technology to make them lightweight and portable. All our controllers are compact, robust and mobile, with stabilised settings which allow for accurate adjustments, achieving the highest quality welds.

All electrical components are soak tested for reliability. Unintentional firing is prevented by safety circuits and in the event of component failure,
system shutdown will occur.

STUDWELDING ACCESSORIES

We stock a wide array of studwelding accessories.
Below are three popular items, but there are many other
offset attachments, centring jigs, extension legs, foot adapters, etc.

chucks CHUCKS

Collets, perhaps better known as chucks fit into the handtool and hold the weld stud during welding. Grip on the stud is motivated by a metal clip or rubber ring.

nosecone NOSE CONE ASSEMBLIES

Used to accurately locate studs when using templates. These are available in three diameters; 30mm (standard), 1 inch and 22mm.

bending bar TESTING NOZZLES

Should be used in conjunction with the DIN tester bending bar. This enables the mechanical testing of welded studs in accordance with DIN267 part 5.

THE ALL NEW CDM8 HANDTOOL

The new smooth ergonomic design of the CDM8 handtool is something we are proud of. As the business end of your studwelding system, the hand tool can take a lot of punishment in a busy production line.

The exceptional build quality of this handtool ensures high levels of productivity, and accuracy whilst all the time minimising operator fatigue.

Take a closer look
pressed-inserts PRESSED
INSERTS

Inserts can work loose, crack paint and leave stains. Holes need to be punched then deburred in parent material, weakening it. The reverse side is not always left flat and the insert is visible and unsightly. The resulting joint cannot always be guaranteed leak-proof.

pressed-inserts REPLACING
INSERTS

Studwelding replaced inserts on these applications, resulting in faster production and stronger joints. Thinner sheet could now be used and with no reverse marking. Corrosion was eliminated as moisture ingress was prevented.

drilling and tapping DRILLING
AND TAPPING

Drilling and Tapping are very slow processes, requiring thicker parent material to achieve full joint strength.
Drills and taps get broken and fasteners can vibrate loose. Through drill holes need sealing and bind holes need clearing out.

drilling and tapping REPLACING DRILLING AND TAPPING

Studwelding allowed this manufacturer to speed up production considerably. Previously he had to leak test every through drilled and tapped hole. An alternative solution of using thicker flanges would have resulted in additional time and cost implications.

through bolting THROUGH
BOLTING

Through bolting is not tamper-proof and is a cumbersome and slow process requiring two-handed assembly with access from both sides.
Holes weaken the parent material and leakage stains from the unsightly bolt heads are common.

through bolting REPLACING THROUGH BOLTING

One component became tamper-proof, a clean design was the biggest benefit on another. On a third part, the gauge was reduced and leakage was prevented. Finally studwelding solved the problem of loose bolts and inaccessibility to the bolt head after assembly.

backwelding PROJECTION AND RESISTANCE WELDING

means taking a component to slow fixed equipment, replacing electrodes and high power consumption costs. Soldering and Brazing requires clamping and causes distortion. Riveting is untidy, irreversible, requires holes, works loose and require reverse access.

backwelding REPLACING RESISTANCE WELDING

removed a bottleneck by not having to take the biggest component to a large resistance welding machine. Replacing Soldering cured a corrosion problem caused by solder flux. Previously brazed components sustained heat damage.

SELECT THE BEST PROCESS

There are three types of studwelding: Capacitor Discharge (CD), Short Cycle (SC) and Drawn Arc (DA). They are complementary and should not be regarded as alternatives. With each method, a weld stud is held in a handtool or production head, then presented squarely to the workpiece. The processes work as follows:

CD   M2.5 to M10
CD PROC
Capacitor Discharge
  • Energy is stored in a bank of capacitors, charged to a pre-set voltage determined by type of stud and parent material.
  • When triggered, energy discharges as a high current pulse, melting the pip to produce an arc.
  • Spring pressure forges the stud onto the molten surface to ensure complete fusion across the flange.
  • Weld duration: Under 4 milliseconds.
Book demonstration
SC   M2.5 to M8
SC PROC
Short Cycle
  • A transformer rectifier supplies a fixed current power source.
  • Triggering produces a pilot arc and the stud lifts to a pre-set height.
  • The main arc melts the end of the stud, producing a molten pool in the parent material.
  • Return spring pressure then forges the stud into the pool. Shrouding gas reduces weld spatter.
  • Weld duration: 10 to 100 milliseconds.
Book demonstration
DA   M5 to M24
DA PROC
Drawn Arc
  • Current, level and duration are determined by the stud diameter.
  • Triggering produces a pilot arc and the stud lifts to a pre-set height.
  • The main arc melts to end of the stud, producing a molten pool in the material.
  • Return spring pressure then forges the stud into the pool. A ceramic ferrule contains and shapes the weld fillet.
  • Weld duration: 100 to 1000 milliseconds
