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.\u003c\/p\u003e\n\u003ch3\u003eFIELD OF APPLICATION\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003eProduct type: Weld stud\u003c\/li\u003e\n\n\u003cli\u003eProduct family: Weld studs\u003c\/li\u003e\n\n\u003cli\u003eMaterial grade: A2\u003c\/li\u003e\n\n\u003cli\u003eStrength class: A2-50 (some dimensions A2-70, see variant)\u003c\/li\u003e\n\n\u003cli\u003eStandard: ISO 13918, type PT\u003c\/li\u003e\n\n\u003cli\u003eThread size: M4–M8\u003c\/li\u003e\n\n\u003cli\u003eDesign: Type PT (pointed end for arc ignition)\u003c\/li\u003e\n\n\u003cli\u003eEnvironment: Outdoor \/ Marine\u003c\/li\u003e\n\n\u003cli\u003eDelivery unit: Piece\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003ch3\u003eFREQUENTLY ASKED QUESTIONS (FAQ)\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does type PT mean and when is it used?\u003c\/strong\u003e\u003cbr\u003eType 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I choose the correct length for the weld stud?\u003c\/strong\u003e\u003cbr\u003eMeasure 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan A2 withstand a marine or saltwater environment?\u003c\/strong\u003e\u003cbr\u003eA2 (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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat welding equipment is required for mounting a type PT stud?\u003c\/strong\u003e\u003cbr\u003eType 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.\u003c\/p\u003e","brand":"WASI","offers":[{"title":"M4 \/ 8","offer_id":55348678623574,"sku":"104500","price":0.75,"currency_code":"SEK","in_stock":true},{"title":"M4 \/
