摘要： A method for producing a component structure from a first component and a second component may involve connecting the first component to the second component by way of a thermal joining process. The component structure has good crash properties, has good vibration resistance, has a lightweight construction, and is produced cost-effectively at least in part because the first component being a steel composite structure comprising a softer layer and a more-rigid layer. The softer layer may have a lower material strength and a higher deformability than the more-rigid layer. A part of a joint zone that is located in the first component may be formed at least partially in the relatively soft layer.

摘要： Embodiments of the present invention comprise a system and method to weld or join coated materials using an arc welding system alone, or in combination with a hot wire system, where the arc welding system uses a welding current having an AC current portion to build a droplet for transfer to the workpiece. In further embodiments, the workpiece is coated with a material, such as zinc, and the arc welding system uses an AC welding waveform which is capable of welding coated workpieces with little or no porosity or spatter and can achieve enhanced performance. Additional embodiments use an enhanced electrode to provide optimum porosity performance. Such embodiments allow for the welding of coated material with little or no porosity and spatter, and at a high welding rate.
