Meco Resistance Welding Capabilities
Automated joining solutions for enclosures, structural assemblies, and leak-proof containers.
Resistance Spot Welding (RSW)
The most common form of resistance welding, RSW joins overlapping sheets of metal at specific "spots." Our automated spot welding cells are ideal for rapidly joining sheet metal enclosures, brackets, and structural assemblies.
- Automated Cells
- Rapid Assembly
Projection Welding (PW)
Small projections are pre-formed on parts to allow multiple simultaneous welds. This process offers greater consistency and longer electrode life, making it perfect for welding weld nuts, studs, or joining thicker materials.
- Nuts & Studs
- High Consistency
Seam Welding (RSEW)
Seam welding uses rotating wheel-shaped electrodes to create a continuous, leak-proof weld. This is the ideal solution for manufacturing sealed containers, fuel tanks, and drums where a continuous joint is required.
- Leak-Proof Joints
- Continuous Weld

Resistance Welding FAQ
What is resistance welding?
Resistance welding (RW) is a thermo-electric process where metal parts are joined by heat generated from resistance to electric current, combined with mechanical pressure. It requires no filler metal or shielding gas, making it highly efficient for sheet metal assembly.
How does it differ from MIG or TIG?
Unlike MIG/TIG, Resistance Welding does not use an external arc or filler rod. It is significantly faster (often taking milliseconds per weld) and cleaner, but it is generally limited to overlapping joints in thinner gauge materials rather than structural butt welds.
What materials are best suited for this?
It is the industry standard for Low Carbon Steel sheet metal (automotive bodies, appliances). Stainless Steel welds excellently. Aluminum can be resistance welded but requires higher current and precise control due to its high conductivity.
Is resistance welding automated?
Yes, it has excellent automation potential. From simple fixed pedestal spot welders to multi-axis robotic arms carrying weld guns, the process is easily integrated into high-speed assembly lines for consistent, repeatable results.
What are the main cost benefits?
The primary benefits are speed and low unit cost. With no consumables (gas/wire) to replenish and cycle times measured in fractions of a second, it offers the lowest cost-per-joint for high-volume manufacturing runs.
