In many industries where metal is used stud welding is providing fixing and fastening solutions.
By avoiding any cutting, drilling or punching access holes in the sheet , stud welding can achieve:-
No reverse marking.
The welded joint is stronger than the parent material or the stud.
Access is only required from one side.
No holes hence no leaking or weakening of the sheet.
Pre-coated or painted material can be welded.
The advantages in studwelding are:-
Studwelding Improves Design:
Stud welding provides an “invisible” fixing for fascia panels, counter tops, signs and badges – for any surface where final appearance, security or hygiene is paramount.
As stud welding does not break through the surface, there is no subsequent risks of leaks or corrosion on, for example, inspection hatches and cover plates; when mounting heating elements or attaching fluid chambers.
Stud welding in ideal for applications where access cannot be made to the reverse side of an assembly, such as mounting circuit boards, rails, instruments, earth points and many different components.
Stud welding is suitable for fixing fluid and air lines, wiring looms, machine guards, handles, insulations and fireproofing materials.
Stud welding replaced inserts in these applications, resulting in faster productions and stronger joints.
Thinner sheets could now be used, and with no reverse marking.
Corrosion was eliminated as moisture ingress was prevented.
Replacing Drilling and Tapping
Stud welding 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
Replacing Back Welding
Here production increased tenfold when studwelding replaced a back welding process. With no need to grind the top surface flat and polish off excess material and burn marks, time saved was significant – reject components were eliminated with additional cost saving.
Replacing Through Bolting
One component became tamper-proof, a clean design was the biggest benefit on another. One a third part, the gauge was reduced and leakage was prevented. Finally stud welding solved the problem of loose bolts and inaccessibility to the bolt head after assembly.
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 a solder flux. Some components which were previously brazed sustained damage because of the long heat cycle – stud welding eradicated this.
