Abstract
A method of single sided spot welding includes the steps of providing a metal tube having a convex surface portion and providing a metal sheet for welding to the metal tube. The method also includes the steps of contacting the metal sheet with the convex surface portion of the metal tube and contacting the metal sheet with a welding electrode. The method further includes the steps of supplying power to the welding electrode for melting metal and solidifying the molten metal to form a weld nugget between the metal sheet and the metal tube.
