The butt welding seam of the long neck flange and cylinder should also be fully welded. 长颈法兰与圆筒的对接焊缝应为全焊透焊缝。
The joints of reinforcing steel after using flash butt welding show that there are only local soften regions in the inside of weld seam and no obvious soften regions in HAZ, and the whole joints have good mechanical property. 钢筋闪光焊接头具有良好的力学性能,接头HAZ不存在明显软化。只在焊缝心部区域出现局部软化,但少许的局部软化并不影响整个接头的性能。
An Analysis and Judgment of Welding Corner Disturbing Echo in Butt Welding Seam Ultrasonic Testing 对接焊缝超声波探伤中焊角干扰回波的分析与判断
Butt Girth Welding Seam X-ray Testing to Natural Gas Transmission Pipeline 天然气输送管线对接环焊缝射线检测
Strength Checking for the Butt Welding Seam between Head and Skirt with Multiple Notch 多缺口的裙座与封头对接焊缝的强度校核
According to the different product structure, butt fusion welding process and lap seam welding process are used to respectively weld left and right half shell of upper body. 上体左、右半壳直焊缝视产品结构不同,分别采用对接熔化焊和搭接缝焊工艺。
Test shows that this way can exhibit good result to butt joint and lap joint of TIG welding and accurately abstract welding seam out, to the welding seam of large magnitude dogleg angle shows good tracking effect ( dogleg angle < 68 °) and procession speed < 100 ms. 实验表明,系统对TIG焊的对接和搭接焊缝有很好地处理效果,对大幅度折线焊缝也能很好的跟踪(折线角>68°),处理速度>100ms。
Shield of Scattered Ray to X-ray Transmission in Butt Welded Seam of Pipes 管道对接焊缝X射线透照时散射线的屏蔽
Flash butt welding joint of reinforced steel bar only resulted in local soften region inside the welded seam but little effect on bulk performance. 显微硬度只在焊缝心部区域出现局部降低,但这并不影响整个接头的宏观性能。
Location of the defect in the butt welded seam of the steel structure with different thicknesses by ultrasonic technique 不等厚对接焊缝中缺陷的超声波定位
It has long been facing the welders that the routine X-ray detection for butt-welded pipe has a high labour intensity and low efficiency-To overcome above disadvantages, a detecting robot has been newly developed to undertake the X-ray periphery welding seam detection for welded pipelines. 针对大口径管道对接焊缝常规X射线检测劳动强度大、效率低的现状,我们研制了管内周向X射线检测机器人。
