Abstract: A system and method of braze resistance spot welding of an aluminum component to a galvanized steel component involve providing an aluminum-side electrode having a first tip defining a rounded shape, providing a galvanized steel-side electrode having a second tip defining a flat shape, depositing a braze filler material between the aluminum and galvanized steel components at a desired location for a spot weld, performing a pre-heat including providing a first current across the electrodes for a first period such that the braze filler melts and removes a portion of a zinc coating from the galvanized steel component, and after performing the pre-heat, performing a spot weld between the aluminum and galvanized steel components by providing a second current across the electrodes for a second period such that the aluminum melts and the galvanized steel does not melt, wherein the second current is greater than the first current.

Abstract: A shielding device for protecting decks from rotting includes an upper member, a pair of opposing main body sidewalls, an upper grip, and a side tab. The main body sidewalls may include a first portion and a second portion terminating with a drip edge. The upper grip may protrude from the bottom of the upper member, and the side tab may protrude from the inner portion of at least one of the main body sidewalls.
