Background
Steel structures are structures composed of steel materials and are one of the main building structure types. The structure mainly comprises beam steel, steel columns, steel trusses and other members made of section steel, steel plates and the like, and rust removing and preventing processes such as silanization, pure manganese phosphating, washing drying, galvanization and the like are adopted. The components or parts are typically joined by welds, bolts or rivets. Because of its light dead weight, and construction is simple and convenient, widely apply to fields such as large-scale factory building, venue, superelevation layer.
Because of the large batch of tensile tests required by the laboratory, some of these tensile specimens require the dotting of the original markings. The dotting process generally uses the original method that a hammer and a metal dotter are used, and the dotter is impacted by the hammer to leave marks on a standard tensile test.
In the dotting process of the tensile standard sample, the dotting effect is different due to different force of each person, the sample is scratched due to overlarge force, and the tensile sample is broken at the dotting point, so that the tensile strength, the yield strength and the elongation after breakage of the final result do not reach the standard; the trace is not easy to leave due to too small force, and the force required by different materials is different, so that the force is strictly controlled, the deformation of a tensile sample in the tensile process is large, the final dotting is fuzzy, the original gauge length cannot be found, and the final elongation after fracture cannot be measured. In GB/T228.1, it is clearly specified that sample dotting needs to be paired, each pair of dotting is on the same horizontal line, and the same group of dotting is difficult to ensure to be in the horizontal position in the traditional dotting, so that the accuracy of elongation after fracture is influenced, and the scientificity and the rigor of a tensile test cannot be met. During the dotting process of the tensile standard sample, the same group of points are not marked simultaneously. In the middle, a large amount of time is needed for comparison and dotting at the same horizontal position, time is often wasted, dotting is not necessarily on the same horizontal line, and therefore errors are generated in the final result, and the rigor of the future test is met.
