1. A manufacturing method for a plate with channels, the manufacturing method including:
a superpositioning step during which a first and a second strip are superposed on one another,
a welding step during which the first and second strips are welded together along a plurality of weld seams,
a blocking step during which zones between the first strip and the second strip, where the zones between adjacent weld seams of the plurality of weld seams open out at one edge of the first strip and one edge of the second strip, are blocked,
a pressurizing step during which a compressed fluid is injected via another edge of the first strip and of the second strip, where the zones between the adjacent weld seams of the plurality of weld seams open out between the first strip and the second strip, to expand the two strips, and
an opening step during which the zones blocked during the blocking step are opened,
wherein the superposition step comprises successively:
a first positioning step during which the first strip is positioned on a base,
a second positioning step during which the second strip is positioned on the first strip, and
a covering step during which supporting parts that together form a first welding channel are arranged on the second strip,
wherein the welding step involves moving a welder along the first welding channel to weld the two strips together along a first weld seam of the plurality of weld seams, and
wherein the supporting parts are moved after the first weld seam is formed to form a second weld channel on the second strip, and
wherein the welding step further involves moving the welder along the second welding channel to weld the two strips together along a second weld seam of the plurality of weld seams,
wherein the method includes a depositing step, between the first positioning step and the second positioning step, during which beads of a thermal insulator are deposited on the first strip, and wherein the second positioning step involves positioning the second strip on the beads.
