Device for checking a weld bead
Devices and methods comprise at least one gauge for inspecting weld seams comprising a plurality of cutouts: a square cutout, a rectangular cutout, a concave cutout with a protuberance; and a straight edge ending with a protruding part. The devices and methods make it possible to inspect the compliance of a weld bead with various quality standards, without taking measurements, or referring to said standards.
1. A device configured for inspecting at least one flaw of a weld bead relative to a welding quality standard, the device comprises a plurality of gauges positioned on one or several elements of the device, the plurality of gauges comprising:
a) at least one first gauge made of a square cutout;
b) at least one second gauge made of a first concave cutout comprising a pilot point extending toward an outside of the first concave cutout;
c) at least one third gauge made of a rectangular cutout; and
d) a first fourth gauge made of a straight edge extending along a first straight line and a sole and unique first protruding part extending at a first distance from the first straight line or having a distal end that is at a first distance from the first straight line.
2. The device according to claim 1 , wherein the first fourth gauge further comprises a second concave cutout positioned between the sole and unique first protruding part and the straight edge.
3. The device according to claim 1 , wherein a side of the square cutout has a length in a range between 1 mm and 30 mm.
4. The device according to claim 1 , wherein a distance between an end of the pilot point extending toward the outside of the first concave cutout and a point situated at an intersection between two edges positioned on both sides of the first concave cutout is in a range between 1 mm and 30 mm.
5. The device according to claim 1 , wherein a length of the rectangular cutout is in a range between 2 mm and 50 mm.
6. The device according to claim 1 , wherein a width of the rectangular cutout is in a range between 1 mm and 30 mm.
7. The device according to claim 1 , wherein the first distance of the sole and unique first protruding part from the first straight line is between 0.2 mm and 5 mm.
8. The device according to claim 1 , wherein the device comprises at least two first gauges, and in that the sides of the square cutouts have different lengths.
9. The device according to claim 8 , wherein the device comprises at least two second gauges, and in that distances between distal ends of pilot points extending toward the outside of first concave cutouts and the points situated at intersections between two edges positioned on both sides of the first concave cutouts are different.
10. The device according to claim 8 , wherein the device comprises at least two third gauges, and in that the lengths of the rectangles are different.
11. The device according to claim 8 , further comprising:
at least one second fourth gauge made of a straight edge extending along a second straight line and a sole and unique second protruding part extending at a second distance from the second straight line of the at least one second fourth gauge or having a distal end that is at a second distance from the second straight line of the at least one fourth gauge, wherein the first distance of the sole and unique first protruding part is a different distance than the second distance of the sole and unique second protruding part.
12. A method comprising:
inspecting at least one dimension of a weld bead by at least one gauge of the device according to claim 1 based on dimensional values of at least one welding quality standard, wherein the at least one gauge of the device is selected from the at least one first gauge, the at least one second gauge, the at least one third gauge and the first fourth gauge of the device.
