TANDEM双丝焊在平面分段流水线中厚板拼板焊接中的应用
TANDEM双丝焊 拼板 MAG焊
2009/4/2
应用TANDEM双丝焊工艺进行平面分段拼板焊接时，对组对精度要求低，母材种类的适用性强，焊缝机械性能良好，热输入低，变形小，减少焊前焊后处理成本，大大提高了焊接效率。在中厚板焊接时熔敷率可达到20 kg／h，是代替埋弧焊的最佳工艺。
为了提高我国工业企业的焊接生产效率和焊接技术水平，珠海市金宝热融焊接技术有限公司从世界著名的德国克鲁斯（ CLOOS ）公司引进了 TANDEM 高速高效焊接技术，并在国内大力推广应用。在过去的10年里CLOOS提供给用户超过1000 套 Tandem 焊接系统。 现已有100多套TANDEM焊接系统在国内使用。
厚壁钢管生产线TANDEM双丝焊在线接带工艺
CLOOS TANDEM 双丝焊
2009/1/9
在大壁厚钢管的生产中，板材必须连续进入轧辊，在每块板材进行焊接时大约有一分半钟的储带时间，必须在这段时间内完成接带，板材宽度为 500~ 1500mm ，管壁厚在 7~ 20mm ，传统工艺一般采用单丝二氧化碳气体保护焊进行连接，但这种焊接方法只能焊接 6mm 厚度以下的钢板，对于厚度大于 7mm 的钢板，无法在限定时间内一次焊成，针对这种情况，采用德国克鲁斯 TANDEM 高速高效焊接设备 , ...
