Fabricator turns up the heat

June 1, 2015


When A.O. Smith, the company known for developing the glass-lined residential water heater, had a bottleneck at its resistance welding station and sought an alternate welding method. It had been making a lap welding on galvanized steel by resistance welding, but this trapped vaporized zinc; escaping vapors weakened the weld. A new method, a butt weld performed by laser welding, doesn’t trap the vapors, leaving a visually appealing weld that is essentially free of defects.
