Background

In various professional skill welder technical contests, relevant requirements and evaluation standards are set for the weld size of metal welding, wherein the convexity of the corner weld is specified clearly. For example, in the technical document of "welding equipment for professional skill and large-scale welding equipment for workers-robot competition and resolution" in 2022, the criterion of convexity of the corner weld is specified: more than or equal to-1 mm and less than or equal to 0mm, and obtaining 10 points; more than 0mm and less than or equal to 1mm, and 7 points are obtained; more than 1mm and less than or equal to 2mm, and 4 points are obtained; 2mm, which is less than-1 mm, to obtain a score of 0; however, the measurement of the amount of concavity and convexity of the corner weld has a problem that it is not easy to measure in actual operation; since there are no specialized measuring tools, the measurement is typically made empirically by visual inspection and estimation, or by existing conventional measuring tools; the results obtained by each measuring person are not comparable due to the different measuring methods, and the measured data are also inaccurate.

Detailed Description

As shown in fig. 1-5, a corner weld convexity gauge, comprising: gauge 1 (thickness is 1 mm's ASTM 304 stainless steel is made), gauge 1 is cross flat structure, four interior angles of gauge 1 are opened respectively and are had two arc mouths 2, have the measurement tongue between two arc mouths 2, the measurement tongue is four measurement tongues A31 that the end radian is different, measurement tongue B32, measurement tongue C33, measurement tongue D34, measurement tongue A31's end is the plane and marks scale 0 on the end, and with measurement tongue A31's plane as datum line 5, measurement tongue B32's end is concave cambered surface and marks scale 1 on the end, and concave cambered surface top point is 1mm apart from datum line 5 subsides, measurement tongue C33's end is concave cambered surface and marks scale 2 on the end, and is 2mm apart from datum line 5 subsides on concave cambered surface top point, measurement tongue D34's end is protruding cambered surface, and marks scale-1 on the top point, measurement tongue D34's end is 5 salient peak distance 1mm.

Preferably, the length of the gauge 1 is 80mm, and the width of the end head is 20mm.

Preferably, a round hole 4 is formed in the end of the gauge 1.

The specific measurement method is as follows:

if the corner weld 6 is concave, the convexity of the corner weld can be measured by the measuring tongue D34, and when the convexity is measured, one of the two sides of the measuring tongue D34 is attached to one side of the corner weld 6, and the gauge is moved downward, so that the end of the measuring tongue D34 is close to the corner weld 6. If the other side edge of the measuring tongue D34 is attached to the other side edge of the corner welding seam 6, the measuring tongue D34 is attached to the corner welding seam, and the convexity of the corner welding seam 6 is-1 mm; if the two side edges of the measuring tongue D34 are attached to the two side edges of the corner weld 6, and the measuring tongue D34 is not contacted with the corner weld, the convexity of the corner weld 6 is smaller than-1 mm; if one side edge of the measuring tongue D34 is attached to one side edge of the corner weld 6, and the measuring tongue D34 is already in contact with the corner weld 6, the other side edge of the measuring tongue D34 is not in contact with the other side edge of the corner weld 6, which means that the convexity of the corner weld is between 0mm and-1 mm.

If the corner weld 6 is convex, the convexity of the corner weld can be measured by measuring tongue B32 or measuring tongue C33, as described above.

If the corner weld 6 is straight, the convexity of the corner weld 6 can be measured by the measuring tongue a31 in the same manner as above.
