With continuous welding, spot welding and discontinuous welding functions, meet different welding requirements. 具有连续焊、点焊、间断焊功能,适合不同的焊接需要。
Experimental study on temperature field of discontinuous welding 间断焊温度场的试验研究
Results indicated that the temperature was much lower while discontinuous welding, but lower axial residual stress can be gained by continuous welding. The annular stress of discontinuous and continuous welding did not have much affection for the pipeline. 结果表明,间断焊可以降低焊接时的温度,而采用连续焊可以获得较小的轴向残余应力,间断焊和连续焊的环向应力对管道的影响不大。
The steel with discontinuous flowline microstructure has lower grooving corrosion susceptibility and only single corrosion groove exists along the welding line. 而不连续流线组织的钢板具有较低的沟槽腐蚀敏感性,在焊缝处产生单腐蚀沟槽。
Numerical simulation on multi-pass welding of T-joint& A comparison between continuous and discontinuous welding 多道焊T型接头的数值模拟&连续焊与间断焊的比较
Numerical Simulation of Multi-pass Discontinuous Welding of T-joint 多道间断焊T型接头的数值模拟
To get the temperature field of discontinuous welding exactly, thermocouple and IR-image equipment were used. 为了准确、全面地得到间断焊的温度场分布规律,采用了热电偶和红外热像仪两套数据采集系统。
Study on strength of discontinuous welding structure 不连续焊接结构的强度研究
It can be concluded that the local high temperature can be reduced effectively using the technique of discontinuous welding and smaller residual stresses are obtained. 结果表明,采用间断焊可以有效降低焊接时的局部高温,而且其残余应力也略低于连续焊。
Contrast the results of the different cases, the entire residual stress zone and three-direction tensile stress condition zone of discontinuous welding are bigger than the continuous case. 对比不同焊接情况的结果,间断焊接会产生比连续焊接更大的应力分布区域和三向拉伸应力状态区,这样对于叶轮的使用和疲劳寿命都是不利的。
There are preheating effect from the welded seam and reheating effect from the sequent weld in the discontinuous welding. 此外,间断焊过程中存在已焊焊缝的预热作用和后续焊缝的再加热作用。
