Description
Drawn Arc stud welding (DA stud welding) is one method of stud welding that creates a lasting weld to a piece of material on a single side. The drawn arc is suited for welding onto thick materials (2mm+). DA products are the only choice for stud welding large diameters, and they can tolerate surface curvature and imperfections such as light rust, grease, and scale. The Drawn Arc stud welding process provides a supremely neat and controlled weld fillet suited to multi-gun applications.

Q&A
Dimensions :
Generally, the nominal length of the stud is ‘after welding’, the studs delivered are 1 to 5mm longer than the nominal length.Only shear connectors’nominal length is ‘before welding’, as its ‘after welding’ length is different according to different welding methods.
Thread :
The threads of our studs are cold-rolled with a tolerance 6g.
Surface Treatment :
DA studs are delivered uncoated unless specified.DA studs are delivered uncoated unless specified.Phosphorition is available as an optional surface treatment
Aluminum Flux :
All SOLID’S shear connectors, and M8 or larger welding studs, are provided with a flux tip.It can help facilitate the ignition of arc, stabilize arc, and deoxidize welding surface.The correct amount of flux is an essential factor of perfect welding results.
Ceramic Ferrules :
Each ferrule can be used only once. It is important to choose the correct ferrules to always obtain stable and good quality welding.
Weld collar :
A weld collar is formed where the stud is welded to work piece. its diameter and height depend on the welding parameters as well as the ceramic ferrule used, the value
in the drawing is approximated according to SOLID’S ceramic ferrule.
Packing :
Plastic bag + Carton box + Plywood pallet, other packing material is available upon request.
