CD weld studs

1. What is weld studs ?

Stud welding is one of the complete fastening system. Weld studs come in a variety of designs, threaded, untreaded, taped, etc., weld studs are used to attach various tools. Stud welding consists of round shaped metal parts with metal work pieces such as sheet metal profiles and pipes this is an economical welding process. Many welding studs are connected through the stud welding process in many areas of the metal industry. Simple handling of equipment technology plays an important role in the process of stud welding. Weld studs can be useful for good quality and permanent connection of high quality metal work with high strength. weld studs can be attached immediately anywhere.

Weld Studs Manufacturer

Stud welding is a technique which similarly used in flash welding. fasteners or nuts are welded to another metal part, i.e. metal or substrate. Fasteners can take any form while using. Nut bolts can be automatically inserted into the stud welder. Weld nuts usually have a flange with small nubs that will melt in the form of weld. Weld studs are used in the stud welding process. There are two main types of stud welding such type are mainly manufactured by manufactures.

2. Stud Welding Process

Stud welding is a process in which a metal stud is attached to a metal workpiece by heating both parts with pressure. An important factor that distinguishes stud welding from other fastening processes is the fastener key that attaches to the work piece without inserting the other side. While running stud welding process, an arc is ignited between the studs and one end of the work piece. And those two joining part is melt and then come together under the pressure of low contact. The stud welding process takes less than a second. Stud welding can be used to join round and rectangular cross-sections.

The arc stud welding method is a very useful and reliable fastening method for a variety of applications. This method allows quick welding of any size or configuration of metal studs to the work piece while providing maximum weld penetration with high reliability. Depending on the customer's demand, components, materials and process requirements, different stud welding processes may be used and their decisive quality and criteria may be used. The diameter of the welding component, the materials and component surfaces used, the thickness of the sheet and the working conditions, the required connected load all play an important role in the manufacturing process of weld studs.

3. Methods of Stud Welding

There are four stud welding methods which are available - Capacitor Discharge Stud Welding , Drawn Arc Weld Studs, Short Cycle Weld Stud, Projection Weld Studs. The stud welding method used depends on the type of stud fastener required, the welded stud fastener can be welded depending on the application and the base metal. Weld studs are made in the following four types

3.1 - Capacitor Discharge Stud Welding

Capacitor discharge stud welding is commonly used to weld small diameter fasteners into thin base metal. The entire weld cycle is completed in milliseconds, welds can be made without pronounced deformation, burn through or reverse deformation. As long as one end of the fastener is designed for CD welding equipment, CD studs can be made in almost any size. Capacitor discharge weld studs are 14 gauge to 3/8 in diameter. 1/4 to 5 and larger lengths are made in different lengths. They are usually made from mild or stainless steel, brass, aluminum and aluminum alloys.

3.2 - Drawn Arc Weld Studs

welding studs for drawn arc stud welding standardly have a pressed-in aluminium ball at the welding tip. This serves as flux for improved ignition and stabilization of the electric arc as well as for deoxidizing the weld pool. These studs range in diameter from 8 to 11⁄4. Length varies from 3/8 to 60. Arch studs are usually loaded on the weld end with an aluminum flux ball Welding process. Draw arc weld studs are usually made of mild steel and stainless steel.

3.3 - Short Cycle Weld Stud

Short cycle stud welding is a quicker form of draw arc stud welding that can use capacitor discharge weld studs instead of drawn arc studs. This method allows the welding studs to withstand thinner sheet metals than the drawn arc process, although it may not obtain as strong or penetrating welds, nor does it require the use of ceramic ferrules. Sometimes operators using this process use overlap gas to reduce spatter.

3.4 - Projection Weld Studs

Stud welding is the joining of round-shaped parts with a flat work piece using a welding arc and the use of pressing force. Projection weld studs and screws are special types of fasteners that are specifically designed to weld another object. Welder machines can also be automatic, with controls for arching and applying pressure. This tool is used to increase the speed and accuracy of CNC stud welding machine production and construction work. Stud welding is versatile; Typical applications include automobile body, electrical panel, shipbuilding and building construction.

4. Benefits of Stud Welding

  • Stud welding is extremely fast. 3/4 fastener completes welding in less than a second.
  • It is one-sided. This means there is no need to enter the other side of the work piece.
  • The stud welding system is also safe. The peripheral welds used for spot bolt welding, stud weld is a full cross sectional weld. This means the full face of the fastener is welded in place which provides a very strong weld.
  • It is aesthetically superior. There are no indicators attached to the fastener as a single sided fastener.
  • It is welded and it will not work for free like press in fasteners
  • No special skills and training are required to work with this.
