Drawn arc types include FD (fully threaded), MD (almost fully threaded), PD (partially threaded), RD (reduced shank), UD (pin), ID (internally threaded pin) and SD (headed stud). Short-cycle drawn arc types include PS (flanged threaded stud), US (pin) and IS (internally threaded pin). Capacitor discharge types include PT (threaded stud), UT (pin) and IT (internally threaded pin). Bolzenschwei\u00dftechnik bsk + BTV GmbH supplies these types. In our range, ND denotes an insulation nail.<\/p>\n<\/div>\n<\/section>\n<section id=\"technik-18\" class=\"brxe-section \">\n<h2 id=\"brxe-huglmf\" class=\"brxe-heading \">What strength class do welding studs have?<\/h2>\n<div id=\"brxe-migzsu\" class=\"brxe-text\">\n<p>Steel studs usually have strength class 4.8 according to ISO 898-1, meaning a weldable steel with specified minimum tensile strength and yield strength. Stainless steel studs are available as A2-70 or A4-70 according to ISO 3506-1. Type SD headed studs have their own material groups with specified minimum values. Bolzenschwei\u00dftechnik bsk + BTV GmbH supplies the appropriate strength class for the application.<\/p>\n<\/div>\n<\/section>\n<section id=\"technik-19\" class=\"brxe-section \">\n<h2 id=\"brxe-idgpwo\" class=\"brxe-heading \">Are stainless steel welding studs available?<\/h2>\n<div id=\"brxe-mbvcfm\" class=\"brxe-text\">\n<p>Yes, welding studs made of austenitic stainless steel are standardised, commonly as A2 or A4 according to ISO 3506-1. They are suitable for higher corrosion resistance requirements. Bolzenschwei\u00dftechnik bsk + BTV GmbH also supplies stainless steel welding elements.<\/p>\n<\/div>\n<\/section>\n<section id=\"technik-20\" class=\"brxe-section \">\n<h2 id=\"brxe-cdlrri\" class=\"brxe-heading \">What is a bimetallic stud?<\/h2>\n<div id=\"brxe-qrftyy\" class=\"brxe-text\">\n<p>A bimetallic stud consists of two materials joined by friction welding. The welding part matches the base material for clean welding, while the remaining part is highly alloyed for improved corrosion protection. Bolzenschwei\u00dftechnik bsk + BTV GmbH advises when such a stud is appropriate.<\/p>\n<\/div>\n<\/section>\n<section id=\"technik-21\" class=\"brxe-section \">\n<h2 id=\"brxe-orbjpl\" class=\"brxe-heading \">Must welding studs be coated?<\/h2>\n<div id=\"brxe-fdkmxn\" class=\"brxe-text\">\n<p>The surface depends on the stud type, material and agreed specification. Capacitor discharge steel studs in class 4.8 are offered with copper plating. This must not be assumed for all drawn arc and short-cycle studs; PD and US are offered without copper plating. Other surface finishes are available by agreement.<\/p>\n<\/div>\n<\/section>\n<section id=\"technik-22\" class=\"brxe-section \">\n<h2 id=\"brxe-zenqey\" class=\"brxe-heading \">How are welding studs designated?<\/h2>\n<div id=\"brxe-veurol\" class=\"brxe-text\">\n<p>The designation according to DIN EN ISO 13918 specifies type, dimensions and strength class, for example a PT threaded stud in M8 with a length of 20 mm and class 4.8. This allows each element to be ordered unambiguously. Bolzenschwei\u00dftechnik bsk + BTV GmbH helps with the correct designation.<\/p>\n<\/div>\n<\/section>\n<section id=\"technik-23\" class=\"brxe-section \">\n<h2 id=\"brxe-dslrzz\" class=\"brxe-heading \">What is the purpose of the ignition tip or aluminium ball on the stud?<\/h2>\n<div id=\"brxe-rvaeeb\" class=\"brxe-text\">\n<p>In capacitor discharge welding, the ignition tip initiates the arc. In suitably designed drawn arc studs, a pressed-in aluminium ball supports deoxidation of the weld pool. The appropriate version depends on the welding process and material. Bolzenschwei\u00dftechnik bsk + BTV GmbH supplies suitable elements.<\/p>\n<\/div>\n<\/section>\n<section id=\"technik-24\" class=\"brxe-section \">\n<h2 id=\"brxe-vsxaik\" class=\"brxe-heading \">What is the purpose of the flange on a welding stud?<\/h2>\n<div id=\"brxe-wvomdm\" class=\"brxe-text\">\n<p>The upset flange increases the welding area.
