If you can weld a studt, Bearcat solves it

Weld Studs

Stud welding consists of carrying out, in just a few milliseconds, a weld without the addition of material. Its objective is to fix the studs to a sheet without drilling or perforating it, creating a heterogeneous joint and reducing production costs.

Bearcat is the only national company dedicated to 100% of stud welding applications. From the automotive industry, civil construction, to the small workshop. With a wide stock of studs, machines and spare parts to attend to your demand “just in time”, and a technical team with more than 40 years of experience in the sector.

What is a stud

A stud is a screw created specifically for welding. There are different kinds: threaded, smooth, with internal thread, insultation pins, fastons (grounding) or even pieces on plan.

 

Types of welding studs

There are two classes of welding studs, depending on the thickness of the sheet and the application:

Capacitor discharge welding

Capacitor discharge welding is common in metalwork, sheet metal work, and the manufacture of hospitality equipment, white goods, etc. It consists of charging a battery of capacitors, discharging it when welding, creating a voltaic arc that volatilizes the tip of the stud. Taking into account the capacity of the capacitor bank and the material of the connector studs, we can weld studs from Ø3 to Ø10. This system is used for plates from 0.5mm to 5mm.

Arc welding

Arc welding of studs is usually used in boiler plants, heavy industry, shipping industry, rail, civil works and mixed works. It consists of welding the studs using a transformer. It is advantage lies in the little importance of the state of the sheet (fats or oils), being able to weld on galvanized sheets or black sheets. Only mild steel, stainless steel and sychromal (high temperature) studs are used for this type of welding.

There are two types of arc welding:

  • Short cycle arc welding: To weld studs in a short welding time, without using ceramic or shielding gas.
  • Long cycle arc welding or conventional arc: To weld studs of large diameters or metric, in long welding time, using ceramic ferrule or shielding gas.
Condensadores

La soldadura por descarga de condensadores basa su principio en la descarga de energía almacenada en una batería de condensadores permitiendo una fusión muy rápida, de 2 a 3 mseg. Debido a la rapidez del proceso es muy indicado para espesores finos en los que no se quiere que marque el anverso. Los pernos llevan una preparación especial en forma de punta.
