Resistance Welding Electrodes

Nut Welding, Stud Welding & Projection Welding

Projection, Nut and Stud Welding

Specialized electrodes for nut welding, stud welding and studs in automotive production lines. We manufacture from the electrode body to the refractory insert, all under one roof.

Projection welding concentrates the current at specific points through preformed protrusions in the part, enabling high-strength joints in M4-M12 nuts, studs and automotive structural components.

• Electrodes with CuW Insert (Class 10-12) High-strength brazing with silver alloy for maximum conductivity and impact resistance
• Ceramic Guide Pins (Zirconia, Si3N4) and KCF Insulating - precise centering, low spatter adhesion, maximum service life
• Stainless Steel Pins Economical, absorb impacts without breaking - require electrode with insulating bushings
• Threaded Electrodes and Bases In-house manufacturing of holders and bases for quick change
• Shunts / Flexible Connectors Braided cables and connectors for current bypass

Spot Welding

Spot Welding

Electrodes for sheet-to-sheet joining in carbon steel, galvanized, stainless and AHSS/UHSS. Standard RWMA geometries (A, B, C, D, E, F) and custom designs to drawing.

• Cold Forged Caps (Female/Male) Compact grain structure for longer service life
• Shanks and Adapters Taper-to-taper connection - Morse #1, #2 and 1:10 (common in Europe and Japan). Ground tapers for hermetic seal
• Welding Arms (Bananas) Class 2 or Class 3 copper with heat treatment for optimal hardness. Manual guns and robots
• Shunts / Flexible Connectors Laminated flexible cables - primary to secondary transformer connection
• Secondary MCM Cables C11000 copper cables for secondary circuit - 250, 350, 500, 750 and 1000 MCM. Air or water cooled

Seam Welding - Forged Wheels

Seam Welding

Wheels and discs for hermetic continuous welding. Critical applications where leak-tightness is mandatory: fuel tanks, transformers, radiators and pressurized containers.

• Forged Wheels (any diameter) Oriented grain structure, zero internal porosity
• Custom Profile Wheels Machined per customer specification
• Re-profiling / Grinding Service Restoration of worn wheels to original profile

Refractory Metal Faced Electrodes | RWMA Class 13 and 14

Tungsten and Molybdenum Insert Electrodes

Refractory material electrodes for welding copper terminals, silver contacts and electrical motor components. Our specialty is precision machining with high-tech equipment that ensures tight tolerances and exceptional surface finishes.

• Tungsten Electrodes (W, WLa10, WLa15, WLa20) For copper terminals in motors and electrical components
• Molybdenum / TZM Electrodes Mirror finish available - no marks on silver contacts
• Elkonite Electrodes (CuW) For precise parameter control in special applications
• Morse Tapers 1 and 2 Standard mounting for electrical contact welding equipment
