Threaded tungsten-copper resistance-welding electrodes

Application

Resistance Welding Electrodes

Threaded electrodes and caps for guns, robots and fixtures

Overview

Why tungsten-copper here

Spot and projection welding electrodes live a harder life than their size suggests: thousands of weld cycles per shift, each one a thermal shock. Tungsten-copper facings and shanks keep their shape where pure copper deforms, cutting dressing frequency and nugget-size variation on high-strength and coated steels.

We machine threaded electrodes to drawing — metric, UNC/UNF and special forms — on a 15-lathe cell, with thread gauges verified per batch. Rods and blocks in both W/Cu grades are stocked for shops that machine their own caps, holders and shanks.

  • Less dressing, steadier welds

    W/Cu faces resist mushrooming, so nugget size stays stable across the shift.

  • Threaded to drawing

    Metric, UNC/UNF or special thread forms, batch-verified with thread gauges.

  • Stock for in-house machining

    Rods and blocks in W/Cu 75/25 and 70/30 for caps, holders and shanks.

  • Robot-cell ready

    Repeatable dimensions keep automated stations running without re-teaching.
