The invention provides a method and apparatus for automatically welding and handling mash welded tailored blank composits. Each completed blank consists of two or more sheets of equal or unequal thickness welded together along linear weld seams, as is conventional. The novel method comprises the steps of: transfering first an second sheet component parts, from respective input stacks of said first and second parts, to an assembly table of a mash welding machine; assembling the sheet components disposed in an overlapping lap joint configuration; welding the lap joint along a linear weld seam, thus defining a welded blank; conveying the welded blank in a timed step manner from the welding machine to an output stacking machine via a magnetic stepping conveyor; tranferring the blank from the conveyor to an output stack of completed blanks with a stacking machine. The apparatus according to the invention comprises: a mash welding machine having an assembly table including means for assembling the sheet components disposed in an overlapping lap joint configuration and means for welding the lap joint along a linear weld seam; stacking machine means for stacking completed blanks into an output stack; means for transferring first and second sheet component parts, from respective input stacks of said first and second parts, to said assembly table of the mash welding machine; and magnetic conveyor means for conveying the welded blank in a timed step manner from the welding machine to said stacking machine means.
