<p>The invention concerns a method to perform reciprocal welding of two tubular metal bodies positioned in such a manner that their axes, in the welding area, form an angle different from 0 DEG between each other, said tubular metal bodies being particularly used to manufacture metal furniture, such as garden furniture or the like. To avoid the inconveniences of usual seam welding, one (10) of the two tubular bodies is submitted to a flattening operation by locally pinching its wall, so creating a double-thick area (12), and then the two bodies (10, 14) are welded by projection with at least partial penetration of the double-wall area (12) into the original shape of the other tubular body (14).</p> |
