Stud Welding

Stud Welding Product Describsion

Stud welding are Befast Fastener’s main product. We are a manufacturer of  stud welding and also a supplier of stud welding. While producing and supplying stud welding, we also produce nuts, washers and other fastener products used in conjunction with them.

Stud welding is a technique akin to flash welding, involving the welding of a fastener or specially formed nut onto another metal part, typically a base metal or substrate. The fastener can assume various forms, usually categorized as threaded, unthreaded, or tapped. Automation is often employed to feed bolts into the stud welder. Weld nuts typically feature a flange with small nubs that melt to create the weld. Weld studs find application in stud welding systems, designed for the two primary forms of stud welding: capacitor discharge stud welding and drawn arc stud welding.

Welding studs are generally divided into three types according to welding principles: Drawn arc stud welding, Short cycle stud welding, Capacitor discharge stud welding

In addition to different materials and strengths, the biggest impact on stud welding is surface treatment. The following are the more common surface treatments for stud welding: zinc plated (ZP), color zinc plating (CZP /YZP), hot dip galvanized (HDG), brass coating, dacromet coating, etc.

Stud Welding Production Process

stud welding are sent from the raw material line to the final product. They generally go through the following process:
Annealing of raw materials – pickling – drawing – forming – grinding – heat treatment – surface treatment – classification – packaging – shipping

The rough schematic diagram is as follows:

Stud Welding Application fields

• Welding studs, also known as weld studs or welding bolts, are commonly used in steel and metal fabrication for attaching other components through a welding process, providing a fast and secure method of attachment.
• These studs find extensive use in construction and structural engineering for securing structural elements, such as steel beams, columns, and plates, to form strong and durable connections.
• Welding studs are employed in automotive manufacturing and repair for attaching brackets, fixtures, and reinforcements to vehicle frames and bodies, as well as in exhaust system installations.
• They are utilized in manufacturing and industrial settings for attaching machinery components, equipment supports, and fixtures, offering a reliable and efficient fastening solution.
• In the aerospace industry, welding studs are used in aircraft assembly and maintenance for attaching various components, brackets, and structural elements to airplane frames and structures.
• They are commonly used in shipbuilding and marine engineering for attaching fittings, equipment, and structural components to ship hulls and marine structures.
• Welding studs also find application in the production of appliances, HVAC systems, and electrical enclosures, providing a method for attaching mounting brackets, panels, and structural supports.
• Additionally, welding studs are employed in various custom fabrication projects, architectural metalwork, and artistic metal sculptures that require secure and visually appealing fastening solutions.
