Weld Studs FAQ
CD vs Arc stud welding, which process fits my job?
capacitor discharge (CD) stud welding
The capacitor discharge (CD) stud welding process uses a bank of capacitors to store energy at a voltage based on stud size and material. When the weld begins, this energy is released through an ignition tip at the base of the stud, creating a fast arc that melts both the stud base and the work surface. At the same moment, the welding gun drives the stud into the surface, forming a permanent bond as the molten metal solidifies. CD welding is effective for studs ranging from #4-40 (M3) to 3/8-16 (M10).
Drawn arc stud welding
Drawn arc stud welding joins a stud to another piece of metal by heating both surfaces with an arc. This method is suitable for larger diameter studs on materials 3/8 inch thick and above. It also performs well on metals with curvature or surface imperfections such as rust and grease.
How do I select stud size and length?
Match diameter to load and base metal thickness. Select overall length, then subtract burn off for post-weld length. Keep required thread engagement in mind. See size ranges from #8 to 1-1/4 inch.
What ferrule type should I use?
Match ferrule to stud diameter and application. Use standard for flat work, angle for corners, thru-deck for decking, heavy duty for higher heat. Order by stud size to avoid mismatch.
Threaded vs unthreaded studs, when to choose each?
Threaded suits brackets and hardware with nuts. Unthreaded suits shear connectors and press-on components. Tapped or reduced-base styles serve specialty fixtures.
Headed Concrete Anchors, where are they used?
Use HCA for steel-to-concrete connection, embed plates, and shear transfer. Follow AWS and ACI guidelines. Pair with correct ferrule and power settings.
DBA studs, what is the role in composite construction?
DBA provides mechanical interlock with concrete. Ribbed profile improves shear performance in decks and beams. Specify bar size, length, and finish per plan.
What standards apply to weld studs?
Common references include AWS D1.1 and ACI 318 for anchors. Material specs often cite ASTM grades for carbon steel and stainless. Check item pages for details.
Installation best practices for strong welds
Clean base metal. Set correct lift, time, and current. Use the matched ferrule. Hold steady pressure until solidification. Verify with bend or torque tests when required.
Materials and finishes available
Stock includes carbon steel and stainless. Options include plain, zinc, or other protective finishes by request. Select finish to match corrosion and appearance goals.
Custom or special studs
Non-standard length, reduced base, special threads, or finishes available through order. Provide diameter, length, material, quantity, and any drawing or spec.
Required protrusion and post-weld length
Plan for specified burn off per diameter. Target post-weld length that meets thread engagement or shear requirements. Confirm in submittals when needed.
Nationwide stock and shipping
Inventory ships from Eugene, Oregon and partner warehouses across the United States. Same-day pickup in Eugene. Fast delivery nationwide.
Strength data and testing
Review tensile, yield, and shear data by size and material. Perform bend or torque tests per standard. Request load tables or submittals during quoting.
Choosing studs for concrete connection
Use headed anchors or DBA per design. Verify diameter, head size, embed depth, and spacing. Follow AWS and ACI provisions for welding and placement.
Stud welding equipment and accessories
Use the correct gun, chuck, and ferrule grip. Replace worn consumables to keep arc consistent. Verify cable size and power source capacity for stud diameter.
