Spot Welding Supplies - Seam Welding Wheels
SCI distributes individually upset-forged and heat-treated seam welding wheels, tube mill electrodes, plate and bar. Most products are available from inventory, or can be custom made to meet your specific needs.
Forged electrodes are available -- either forged and heat treated-only, or fully machined-to-print -- in RWMA Class 2, 2-premium, 3 and 4 materials. Click on Resistance Welding Copper Alloys for details and availability.
There is a direct relationship between production down-time and the method of manufacture of seam welding wheels (resistance welding electrodes). Individually upset-forged welding wheels outperform cast wheels every time, making them the clear choice for extending electrode life. Many RWMA suppliers do not understand the importance of, and do not supply, individually forged wheels.
Why upset-forged seam welding wheels perform better, last longer...
How to tell them apart...
Every wheel we produce is individually forged and heat treated. Each customer job is internally certified under our quality system of process verification. Certification is essential to ensure that your wheels are individually forged.
If the wheels you're currently using are performing poorly, ask your supplier to certify method of manufacture. Suppliers sometimes do mix wheels. If you're not satisfied, we'll gladly test them for structural form.
