Products :

Speciality weldable fasteners / hardware used for stud welding, for Capacitor Discharge and Drawn Arc / Short-Cycle Applications conforming to EN ISO 131918 standard and Projection studs for Resistance Welding are available. We offer a complete range of capacitor discharge / stored-arc / tip-ignition studs for processes specified by the EN ISO 14555 standard.

Capacitor Discharge Welding Studs with diameters from M3 to M8 with or without threads, or with interval thread tapped bush, in Mild Steel or Stainless Steel (304, 316); Aluminium Alloy AlMg3, or in special sizes (square / round), lead-free Brass studs are available in standard lengths from 8 to 40 mm in increments of 2 mm vize. M3x10, M3x12, etc. and threads according to Metric/UNC or Imperial (BSW) dimensions.

Projection Welding studs are available in standard dimensions up to M8 in diameter in Mild Steel and Stainless Steel.

Capacitor Discharge Stud Welding - A User Friendly Process For Instant Fastening :
[ Features / Advantages ]

• Saves Time : A stud weld takes only a split-second to make and only two-three seconds to re-load the welding tool
• Saves Material : The component to which the fasteners are welded is not weakened by drilling - as a result plate thickness can be reduced. In addition, this process alleviates the need for punching holes and what's more - the reverse face of the component can be painted or covered as there is no rear side marking.
• Saves Labor : Semi-skilled operators too can quickly learn to make perfect stud welds ... consistently.
• Increases Design and Production Flexibility : Access is only necessary from one side of the job - the equipment is readily portable and may even be bench-mounted. The designer has greater freedom and this production flexibility, with special auto-feeding studs, makes it possible to have methods of assembly that would otherwise be impractical.
• Product Quality : Provides leakproof fastening. Leaves a smooth unbroken finish on the rear/reverse side of the component or fabrication.
• Wider choice of metals : Dis-similar metals can be welded as long as both are conductive, e.g. brass to steel, brass to copper, aluminium to die-cast zinc.

Standards :

Our products conform to ISO 13918:1998 standard, which supercedes the DIN 32501 (type 1 to 5) standard. The high quality is readily apparent from the high break loads (torque values) of the product.

Quality Control :

Every batch of studs that leaves our factory is subjected to thorough inspection and testing. Test certificates are issued with each batch as per standard Quality Control norms.

The studs can be tested by mechanical / destructive testing, using a torque wrench. This indicates whether the strength is within prescribed torque values. Non-destructive inspection can be conducted by using a torsion meter or other methods specified in the AWS Handbook (Vol. 3, 9th edition. Ref :C5.4-93. "Recommended Practices For Stud Welding" ).
