Product ID : PD, RD, UD, ID Weld Studs
Product Attributes :
hreaded studs accord to DIN EN ISO 13918:2017 – with a reduced welding tip to an approximate core diameter.
Studs made of the materials steel blank 4.8, 1.4301 and 1.4571 without aluminium ball are generally in stock.
Arc stud welding is popular because of what it offers: the ability to quickly and efficiently join a metal stud to one side of a metal work piece without marring the other side. Dependability and ease have made stud welding one of the most utilized methods of fastening on offshore platforms and shipyards across the globe.
Nominal dimensions are listed. The tables divergence in outline shape, finish or dimensions shall be permitted, provided the welding area complies with the specifications of the said tables. The length after welding, l2, is a design value. By proper control of the welding it is possible to keep variations in l2 to within ± 1 mm. Under special conditions, l2 may be constantly different from the nominal value. The form of the central part of the stud tip comprised inside the diameter d1/3 for stud types UD, SD (d2/3 for stud types PD, RD, ID) shall be at the manufacturer’s discretion. The tip shall be at the manufacturer’s discretion in the case of flux in the form of a press-fitted aluminium ball (e.g. flattened in the centre with a diameter not exceeding 0,5 d1).
