A clamping device for butt welding metal sheets includes a base for supporting adjoining edges of a first and a second associated metal sheet. A first clamping unit is positioned above the base. The first clamping unit includes a plurality of first springs longitudinally spaced from each other. Each first spring has a first end, for selectively contacting the first associated metal sheet, and a second end as well as a first support linkage to which the second ends of each of the plurality of first springs are secured. The support linkage selectively applies the plurality of first springs to the associated first metal sheet. A second clamping unit is positioned above the base in a spaced manner from the first clamping unit. The second clamping unit includes a plurality of second springs longitudinally spaced from each other. Each second spring has a first end for selectively contacting the second associated metal sheet and a second end. The second ends of each of the second springs are secured to a second support linkage. The second support linkage selectively applies the plurality of second springs to the associated second metal sheet.

A clamping device for butt-welding material sheets together comprising: a base for supporting adjoining edges of a first and a second associated sheet of material; a first clamping unit positioned above said base, said first clamping unit comprising: a plurality of first springs spaced from each other, each first spring having a first end, for independently contacting the associated first sheet, and a second end, and a first support linkage including a pivoting member to which said second ends of each of said plurality of first springs is secured, for selectively applying a force by said plurality of first springs in a downward and inward direction to the associated first sheet; a second clamping unit, positioned above said base and spaced from said first clamping unit, said second clamping unit comprising: a plurality of second springs longitudinally spaced from each other, each second spring having a first end, for independently contacting the associated second sheet, and a second end, and a second support linkage including a pivoting member to which said second ends of each of said plurality of second springs is secured, for selectively applying a force by said plurality of second springs in a downward and inward direction to the associated second sheet.
