Description

Stainless steel A2 type PT weld stud is intended for use where a permanent, threaded fastening point is needed without through-holes. The product complies with ISO 13918 and is used where rapid stud welding and high corrosion resistance are required. It is suitable for professional installations where long service life and consistent performance are critical.

FIELD OF APPLICATION

The product is used in the construction, ventilation, and marine industries, for example in the assembly of sheet metal, railings, cable ladders, and ventilation fittings. It is intended for applications where rapid stud welding without through-holes is required and where the choice of material provides the necessary protection against corrosion and mechanical stress.

FREQUENTLY ASKED QUESTIONS (FAQ)

What does type PT mean and when is it used?
Type PT has a pointed end used for drawn-arc stud welding with a ceramic ferrule. This method provides complete fusion and high pull-out strength, making it suitable for thicker materials and load-bearing fixings, unlike capacitor discharge studs used on thinner sheet metal without a shielding gas.

How do I choose the correct length for the weld stud?
Measure the thickness of the material to be mounted over the stud plus the desired thread length for the attached nut or component, and add a few millimeters for the material consumed in the weld bead during drawn-arc welding.

Can A2 withstand a marine or saltwater environment?
A2 (equivalent to AISI 304) tolerates moisture and moderate chloride exposure well, but for continuous contact with saltwater or high chloride exposure, acid-resistant A4 (AISI 316) is recommended instead for better corrosion resistance.

What welding equipment is required for mounting a type PT stud?
Type PT requires equipment for drawn-arc/short-cycle stud welding with a compatible power source and a ceramic ferrule around the stud during welding, unlike capacitor discharge welding which does not require a ferrule.
