Stud Welding

With over 20 years’ experience in stud welding operations, FASTEN is undoubtedly Singapore’s leading stud welding expert.

Fasten Enterprises provide on-site and work services for the fixing of shear connectors, including thru-deck stud welding. We also supply a large range of shear connectors and stud welding equipment from NELSON Stud Welding.
Currently, our sales network is supplying more than 3 million studs per year across different projects and applications.

We also provide rental services of Stud Welding Machines to project sites and steelyards. Our NELSON Stud Welding Machines are at the top of its class in stud welding and Where site space is limited, we can also supply inverter units, if required.


Stud Welding

Welding thru-deck is a common practice in the composite slab design. The shear connectors (or shear studs) are welded by the drawn arc stud welding machine. As stated in the ISO 13918 standard, there are two types of ceramic ferrules, one for direct welding (directly welding on the beam), and the other for thru-deck welding. No holes are required on the metal deck and there is no need to clean or finish the metal deck after the process.

Stud welding is an extremely quick fastening technique. To use stud welding on a large scale, users can speed up the process by using a heavy-duty NELSON Stud Welding Machine. With the training provided by the Fasten Technical Team, your workers can create up to eight stud welds per minute.

When it comes to your power source, consult our Fasten Technical Department for the recommended fusing, primary wire size, and primary wire length for the power source to be used. Inadequate primary power or incorrect wire size or length can contribute to a reduction in weld current when some rectifier type power sources are used. Inadequate power or fusing can also hamper the starting and output current for the generator.

It is essential to have the correct weld current and weld time to achieve a good weld. When excessive cable lengths are used, our Fasten Technical Team will look into the reduction in weld currents and adjust the settings accordingly for our users. Without technical support, these factors may contribute to weld inconsistency or even weld failure. The amount of cable totally depends upon the power source being used. Our technical department will advise if there is a need to parallel cable when long runs are needed.
