This series butt welding machine is applicable for the vertical electroslag butt welding of 14-36mm,1 ,2 ,3 ,level twisted bar joints in cast-in-place concrete-steel structures of high-rise, bridge, chimney,tower and so on . It can also be used as a general electric arc welding machine to weld all steel structures.
Using this series machine and advanced jigs to conduct electroslag butt welding operation can completely replace the traditional welding mathods, such as binding welding, squeezable welding, assistant electric arc welding, and joint electric arc welding. So it enjoys many features, such as reliable welding quality , high efficiency, saving energy and a large amount of steels.According to the practical operations.
it is proved that using this series machine for welding operation can save 20-35%of the total steels, the cost of each joint is only about 10%of the cost in traditional joint electric arc welding operation , and the rate of work increases by 8-10 times. If one set of this series machine is allocated 1-2 welders and 2-4 assistants, then each shift
98hours)can weld more than 300 steel joints on the vertical shafts or horizontal beams, enjoying remarkable economic and social benefits .
Features and Structures
This welding machine is composed of welding transformer, shift switch,current adjusting handle, vertical welding jig and some other parts.One power can support two or more jigs at the same time to conduct flow operation and increase working efficiency .
The power input loop used SCRto control the contactless electronic switch, enjoying the features of sensitive control ,high reliability ,long life-span, non vibration, and non noise. After finishing the welding of each joint, the electronic switch will automatically cut off the current to aviod the no-load wastage ,having remarkable no-load energy -saving effect.
During the process of welding operation , the voltage and time show on the same screen at the same time, so it is so easy to operate that ordinary workers can learn how to u
