管极电渣焊(又称管状焊条丝极电渣焊)是熔咀电渣焊的改进形式。这种方法的优点是:设备比较简单,生产率高,质量稳定,焊后状态未经正火处理机械性能仍可达到压力容器的要求。现将试验情况小结如下: 管极电渣焊实质管极电渣焊和熔咀电渣焊的原理基本相同,其不同点是熔咀电渣焊采用极状电极作为焊丝导向,导电和填充金属;管极电渣焊是将板状熔咀简化为管状熔咀——外带特种涂料的钢
Pipe Electroslag Welding (also known as the tubular electrode wire electrode electroslag welding) is meltblown electroslag welding improved form. The advantage of this method is that the equipment is relatively simple, the productivity is high, the quality is stable, the mechanical properties of the post-weld state without normalizing can still meet the requirements of the pressure vessel. Now the summary of the test are as follows: Tube Electroslag Welding Tube Electroslag welding and melting Tsui electroslag welding principle is basically the same, the difference is the meltblown Electroslag welding pole electrode as the wire guide, conductive and metal filler ; Electrode Electrode Welding is the simplified tube-shaped melt Tsui tubular melts Tsui - takeaway special coating of steel
