That is, as a result of finite element analysis performed on the first steel plate 1 and the second steel plate 2, when the thickness values of the first steel plate 1 and the second steel plate 2 are 15mm, the structural parameters L, W and θ are selected to be L equal to 9mm, W equal to 4mm, and θ equal to 48 °, the stress values applied to the first steel plate 1 and the second steel plate 2 are the smallest, and at this time, the engagement effect between the protrusion 3 and the engagement groove 4 is the best, which is most beneficial for the welding operation.
Specifically, the structural parameters of the bump 3 are obtained by obtaining the structural parameters of the bump 3 through finite element analysis of the first steel plate 1 and the second steel plate 2
(unit mm),
(unit mm),
(unit °), stress applied to the first steel plate 1 and the second steel plate 2 during the joining process can be minimized, and the joint between the first steel plate 1 and the second steel plate 2 can be firmly secured.
The specific welding process of the jointed board welding method in the embodiment is as follows:
first, according to the thickness values H of the first steel plate 1 and the second steel plate 2, and
calculating the sizes of the convex block 3 and the clamping groove 4; then, according to the calculated structural parameters L, W and θ, the bump 3 is formed on the first side surface 11 of the first steel plate 1, and the engaging groove 4 is formed on the second steel plate 2.
Then, the bump 3 is clamped in the clamping groove 4, so that the first side surface 11 of the first steel plate 1 is abutted against the second side surface of the second steel plate 2, and the first steel plate 1 and the second steel plate 2 are connected once.
