The weld specimen with an overlap defect contained a large cavity-type defect inside the weld bead, which significantly reduced the fatigue life. When the surface of the defective test piece was peened, the fatigue life of the weld plate was restored, resulting in an equivalent or ...
a1. Welding plate after,Welding plate and product overlap there will be a squeeze,Extrusion can cause wafer and gold thread damage and fracture can lead to produce light。 1. 那里焊接板材以后,焊接板材和产品交叠将是挤压,挤压可能导致薄酥饼,并且金螺纹损伤和破裂可能带领导致光。[translate]...
Glass ribbon in the defect measuring method and the glass ribbon in the defect measuring system And if there is a defect in the vicinity of the interface of the glass ribbon, even if the defect is large, to provide a glass ribbon in the defect measuri... 藤井 信治,楜澤 信,吉川 信 ...
In narrow overlap welding, serious defects in the weld will lead to band breakage accident, and the whole hot dip galvanizing unit will be shut down. Laser vision inspection hardware is used to collect real-time image of weld surface, and image defect recognition and evaluation system is ...
Accordingly, the size of the hook-like defect in a weld joint obtained through welding of the tool is greatly reduced, and the strength coefficient of the joint is remarkably improved.宋友宝杨新岐
Last, to achieve real-time detection of narrow overlap welding, a two-stage defect recognition model is built which greatly improves the efficiency of weld defect identification without affecting the accuracy of weld defect identification.doi:10.1016/j.jmsy.2021.01.012Rui Miao...
The microstructures with a welding zone and heat-affected zone mainly consisted of upper bainite. The hardness value was highest in the welding zone and lowest in the base material. During the pull-out tests, all the welds failed in the stud. Moreover, the defect-free welds broke at the ...
friction stir welding soldering set of overlap passes through the setting of emery wheel board, can be in welding process effectual deburring defect, obtain the glossy welding seam of high -quality surfacing, has avoided welding back machinery and technology such as has polished to the material ...
Purpose: a method of for feeling that being superposed between the weld metal in mash seam welding prevents the defect of welding, by measuring superposition between the displacement of one end face of weld metal and notifying whether a user changes within permissible range. Construction: several ...
defect,in which the up-trend was larger.When R was equal to 0.1,the fatigue strength Δσk of Aluminum alloy FSW overlap joints was 18.25MPa for the 95% survival probability,which meant an increase of 31.11% as compared with the Δσk=13.92MPa of Aluminum alloy fusion overlap welded ...
