Abstract: Welding techniques, including, for example, resistance spot welding, can be used to join or weld two or more metal sheets together. A clamping force (204) and an electric current (212) can be applied to two or more sheets to create localized melting that combines the material of the two sheets. Applying a clamping force (204) and a cooling current (224) can include gradually decreasing the amount of the electric current applied to the weld while applying the forging force. By adjusting the amount of the electric current applied to the weld can allow the weld to cool gradually, which may reduce thermal stresses and allow the forging force to close cracks, pores, or otherwise be used to remove or prevent defects (102) formed in the weld.

Abstract: Disclosed are aluminum alloy products and methods of making and processing such products. Thus, disclosed are aluminum alloy products exhibiting controllable surface properties, including excellent bond durability, low contact resistance, and corrosion resistance. Aluminum alloy products described herein include a migrant element, a subsurface portion having a concentration of the migrant element, and a bulk portion having a concentration of the migrant element. The aluminum alloy product comprises an enrichment ratio of 4.0 or less, wherein the enrichment ratio is a ratio of the migrant element concentration in the subsurface portion to the concentration in the bulk portion. Additionally, the aluminum alloy products surface and/or subsurface can contain phosphorus (e.g., elemental phosphorus or oxidized phosphorus). The phosphorus containing surface provides reduced electronic stress on an electrode tip of a resistance spot welding apparatus, and an extended service lifetime (e.g., weld cycles to failure) of the electrode tip.

Resistance spot welding includes positioning a first metal sheet and a second metal sheet between two electrodes, contacting the two electrodes together on to opposing surfaces of the first metal sheet and the second metal sheet, and applying at least a minimum current to the first metal sheet and the second metal sheet through the two electrodes to form a weld having a minimum weld size to join the first metal sheet with the second metal sheet. At least one of the first metal sheet and the second metal sheet is a fusion alloy where the composition of at least one outer layer of the sheet is different from the composition of the core of the sheet.

Abstract: Systems and methods are described for roll-forming metal substrates. The metal substrates are subjected to induction heating during the roll-forming process by exposure to time-varying magnetic fields, such as by exposure to a rotating permanent magnet, or exposure to laser radiation from a laser source. Heating of the metal substrates allows improved formability or plasticity of the substrate in order to reduce or eliminate damage to the substrate during roll-forming to low bending radius to thickness ratios. Heating of the high-strength metal substrates can also function to temper the substrates and/or improve surface corrosion resistance and form high-strength end products with desirable properties.
