Unique Applications

Comprehensive Stud Welding Solutions for Structural Steel & Sheet Metal

ZOC provides complete stud welding solutions for demanding job sites and production lines—from heavy-duty drawn arc stud welding machines for structural steel (plate thickness ≥ 3 mm) to capacitor discharge (CD) stud welding machines for thin sheet metal (0.5–3.0 mm). Our systems are widely used in steel structures, bridges, composite floor slabs, high-rise buildings, embedded parts, power plants, shipbuilding, and heavy machinery, as well as cabinets, enclosures, HVAC ducts, appliances, and metal products. Suitable for welding shear connector studs, threaded studs/bolts, screws, pins, insulation studs, and anchor parts. Share your application details to get the best stud welding machine recommendation and specifications.

Material Compatibility

All-Position Stud Welding Material Compatibility

ZOC Stud Welding Machines support all-position stud welding (flat, vertical, overhead, and angled) across a wide range of arc-weldable metals, including low-carbon steel, stainless steel, alloy steel, copper, and aluminum. On structural steel and thicker plates (typically ≥ 3 mm), the drawn arc stud welding process delivers stable arc ignition and repeatable fusion. Meanwhile, on thin sheet metal (0.5–3.0 mm), a capacitor discharge (CD) Stud Welding Machine helps minimize burn-through and backside distortion, although the final process selection depends on your application. To achieve the best weld quality, use clean, smooth surfaces and remove oxide, oil, primer/paint, and plating in the weld area; additionally, galvanized steel should be cleaned to bare metal at the welding spot. Share your base metal, plate thickness, and stud type/diameter for a quick weldability check and model recommendation.

Quick Answer

Stud Welding Machine FAQs

Find quick answers about our stud welding machines, including drawn arc stud welding machines for structural steel and capacitor discharge (CD) stud welders for thin sheet metal. If you share your plate thickness, stud type/diameter, and base metal, we can recommend the right model and parameters.

Carbon steel, stainless steel, and low-alloy steel are common. Aluminum and copper are possible case-by-case. For best results, remove oil, oxide, paint/primer, and plating in the weld area (clean galvanized steel to bare metal at the spot).

Yes. We offer multiple power levels and stud diameter ranges (e.g., M3 to larger sizes depending on the model). Share your stud diameter and output target for a recommendation.

Yes. We can provide automation-ready configurations (e.g., remote start/I-O and fixture integration). Tell us your workflow and requirements.

Export-grade packing is available, including reinforced pallets and wooden-case options, plus shipping documents support.

Lead time depends on model, quantity, and customization. Shipping is available by sea, air, or land—send your destination for an accurate quote.

In most cases, use a drawn arc Stud Welding Machine for structural steel and thicker plates (typically ≥ 3 mm). Choose a CD Stud Welding Machine for thin sheet metal (0.5–3.0 mm) to help minimize burn-through and backside distortion.

CD stud welding typically requires no ceramic ferrules and no shielding gas. Drawn arc stud welding often uses ceramic ferrules; shielding method depends on stud type and application.

Advantages of double gun stud welding machine

With the adoption of dual core technology, our welders have peace of mind.
ZOC Double Gun Stud Welding Machine, when used, is equivalent to two Stud Welding Machines operating separately, welding does not affect each other, welding speed is fast, quality is good, and efficiency is high. So why not use two Stud Welding Machines directly? In addition to the characteristics of IGBT inverter single machine, this welding machine also has the following advantages:
