Seam Welding Services: How Continuous Resistance Welds Seal Tanks, Bellows, and Enclosures
Seam welding services produce a continuous, leak-tight joint by rolling two sheet-metal workpieces between a pair of rotating electrode wheels while a pulsed current flows through the interface. Unlike a row of overlapping spot welds, a true seam weld is an unbroken fusion line, which is why it is the standard choice for fuel tanks, […]
Resistance Welding Services: Spot, Seam, Projection & Butt Welding for Production
When your production line demands thousands of identical, repeatable joints every shift, few processes beat resistance welding. By passing a controlled electrical current through the part itself and squeezing it between copper electrodes, resistance welding creates a clean, solid-state bond in a fraction of a second—no filler wire, no shielding gas, no open flame. At […]
Spot Welding Services: Fast Sheet-Metal Joints
Spot Welding Services: Fast Sheet-Metal Joints Spot welding (resistance welding) joins sheet-metal parts by passing a concentrated current through overlapping sheets between copper electrodes, fusing them at discrete points in milliseconds. For automotive bodies and enclosures, it’s the high-speed way to make strong, clean joints without filler. This guide covers how it works, when to […]
