The current edition is DIN EN ISO 13918:2021-12. Design must use the confirmed properties of the welding elements supplied and the requirements applicable to the application.<\/p>\n<p><strong>Strength values of welding elements<\/strong> describe the mechanical properties of welding elements. They must be distinguished from the load-bearing capacity of the finished welded joint. The mechanical forces a threaded stud or headed stud can withstand permanently after joining depend on factors including material, joint geometry, welding execution and loading. In this technical section, Bolzenschwei\u00dftechnik bsk + BTV GmbH provides a verified overview for designers, quality inspectors and production planners in mechanical engineering and structural steelwork. To monitor these loads in accordance with standards, all elements used must meet strict criteria. Detailed regulatory requirements can be found on our information page about <a href=\"https:\/\/www.stud-welding.de\/en\/service\/din-standards\/\">DIN standards in stud welding<\/a> .<\/p>\n<\/div>\n<\/section>\n<section id=\"technik-2\" class=\"brxe-section \">\n<h2 id=\"brxe-kzrefv\" class=\"brxe-heading \">Strength values of steel and stainless steel welding elements<\/h2>\n<div id=\"brxe-kjrysp\" class=\"brxe-text\">\n<p>The table summarises the key mechanical properties of common fastening elements. For conventional welding studs of strength class 4.8 according to ISO 898-1, for example, the tensile strength (Rm) is at least 420 N\/mm\u00b2 and the yield strength (ReH) is 340 N\/mm\u00b2, with elongation at break of at least 14 percent. For stainless steel, such as the weldable material A2-50 (AISI 304 \/ 1.4301) according to ISO 3506-1, tensile strength is at least 500 N\/mm\u00b2. These material properties form a basis for design. The load-bearing capacity of the welded joint and the specific loading must also be demonstrated.<\/p>\n<\/div>\n<\/section>\n<section id=\"technik-3\" class=\"brxe-section \">\n<h2 id=\"brxe-oqlowf\" class=\"brxe-heading \">Which parameters apply to aluminium and brass welding studs?<\/h2>\n<div id=\"brxe-regywj\" class=\"brxe-text\">\n<p>Precise load-related parameters are also essential for materials other than steel and stainless steel. Capacitor discharge welding with tip ignition frequently uses welding elements made of brass (CuZn37 according to EN 12166) with a tensile strength of at least 370 N\/mm\u00b2, or aluminium materials. Pure aluminium studs (EN AW-Al 99,5) achieve at least 100 N\/mm\u00b2, while the stronger AlMg3 alloy (EN AW-5754 according to EN 573-3) has a tensile strength of at least 180 N\/mm\u00b2. The relevant material properties must be confirmed for the welding elements supplied. Applicable standards and process-specific DVS technical bulletins must be consulted for the welding process.<\/p>\n<\/div>\n<\/section>\n<section id=\"technik-4\" class=\"brxe-section \">\n<h2 id=\"brxe-mjbsjh\" class=\"brxe-heading \">How do correct material data support quality in your production?<\/h2>\n<div id=\"brxe-rfkssp\" class=\"brxe-text\">\n<p>Correct mechanical material data support design. They alone do not exclude component failure under static or dynamic loading; geometry, weld quality, loading and the required evidence must also be considered.
