Frequently asked questions

Conventional Studs, generally with both ends threading, are used for fastening two objects, say plates. A hole is drilled in one plate and a drill and tap in another plate. Stud is fitted in one plate and another plate is clamped, using a nut. Weld Studs are directly welded to one plate, in fraction of a second. Another plate with drilled hole, is clamped with nut to studded plate. Thus, cumbersome & time consuming operation of drilling & tapping is avoided. No leakage through tapped hole. Very high productivity is achieved.

Depending upon the method of welding, studs are classified into following types:

  • Drawn Arc studs (welded by generation of arc between stud and base metal). Ceramic ferrule is used for drawn arc welding. (M6~M20)
  • Capacitor Discharge studs (Welded by discharging current through the stud. The charge is stored in a bank of capacitors) (M3~M8)
  • Projection Weld Studs / Weld Bolts – These are welded by pasing current through projections which are present under the head of stud. (M5~M12)
Automotive – Studs welded on frame for fitting external parts like dashboard, bumper, etc
Transformers – Studs are welded on transformer tanks for ease of fastening lids, etc.
Boilers – Non-threaded studs are welded on surface of boiler tubes like fins to increase the surface are for heat dissipation.
Construction – Shear connectors, a type of Drawn Arc weld stud, is used in construction as reinforcement in RCC / composite structure
Sheet metal fabrication – CD studs are extensively used in fabrication and also in control panels.
  • High Productivity – Process lasts for fraction of a second only.
  • Costly and time consuming operation like drilling, punching, threading, riveting, etc are eliminated.
  • Thin plates can be used as base material.
  • Strength of joint is higher than base material and stud

The type and material of stud is selected depending on following factors:

  • Application (heavy/light duty)
  • Torque requirement
  • Material of base metal
  • Thickness of base metal
  • Surrounding environmental conditions

Ferrules are ceramic rings, used during welding of drawn arc weld studs. It is mainly used to:

  • Confine the molten metal at base of stud
  • Provide protection from oxidation
  • Protect welder’s eyes from bright arc light
  • Thickness of base metal
  • Provide proper path for gases to escape

One ferrule is required for every Drawn Arc stud and it is broken after welding.
