The contact state of the bolt joint surface has an important influence on the contact stiffness, damping, and other properties of the equipment. To obtain the contact state of the bolt joint surface, the method to detect the contact state of the bolt joint surface based on laser ultrasonic technology is proposed in this paper. The reflectivity under different working conditions is obtained by the reflection amplitude of the longitudinal wave before and after bolt tightening. The relationship between reflectivity and bolt torque is studied. The results show methods proposed in this paper can effectively detect the contact state of the bolt joint surface, and it provides a basis for the study of the mechanical properties of the contact surface.

“…Q550D high-strength low-alloy (HSLA) steel is smelted by adding an alloy solid solution on the basis of carbon structural steel [9]. By reinforcing the solution, the inner ferrite of Q550D is deformed, the hardenability and tempering stability of the steel are improved, and the strength of the steel is enhanced [10].…”

The microstructure and mechanical properties of the welded joints of 6252 armor steel and Q550D high-strength low-alloy (HSLA) steel welded by MIG welding were studied. ER70S-G and ER140S-G were used as fillers to obtain welded joints with good formation and no faults. The joint microstructure (OM) analysis showed that a large Widmanstätten structure was observed at the fusion line on the Q550D side, and the apparent grain sizes changed on the 6252 side. Cylindrical ferrite growth along the bainite grain boundary was observed in the ER70S-G filler weld zone, while the ER140S-G filler weld zone was occupied by lower bainite structures. The XRD phase analysis showed that more Fe-Ni-Cr compounds and less ferrite were formed in the ER140S-G filler weld. The hardness test showed that the hardness of the HAZ on the 6252 side was significantly higher than that of the BM and the WZ, and the welded joint obtained by the ER140S-G filler had a higher hardness. The tensile strength test showed that WZ (>772 MPa) had a higher strength than Q550D BM, and the tensile fracture (SEM) was primarily a ductile fracture. The impact test results showed that the welded joint had better impact resistance at room temperature, but the impact absorption energy of the weld and the heat-affected zone was strongly affected by changes in temperature, and brittle fracture occurred easily at low temperatures.

This paper presents the finite-element analysis of the shear-connection shear-out fracture (SOF) performance, covering the prediction of the SOF displacement at fracture and surface and through-thickness fracture failure analyses. The appearance of fracture on the connected plate surface, taken, as the SOF initiation in published literature is not the accurate SOF initiation. This work proposes using SOF displacement or fracture strain as a displacement or strain-based fracture limit state for shear connections that exhibit the SOF. The displacement or strain at fracture initiation at the middle-thickness of the connected plate represents the accurate SOF displacement or strain at fracture.
