Impulsion Controller for ARC Welding
Updating Time:2016-1-13 11:10:45 Hits:

1.       Introduction

This equipment can be used as a accessory of arc welding machine. Able to be connected easily to the welding machine, such as LINCOLN DC series(DC-400, DC-600, DC-1000), it is a improving method and reduces production cost.


2.       Impulsive submerged-arc welding

This newly innovation welding method can be used to improve welding velocity markedly without lower welding quality. Shanghai boiler factory added this accessory to submerged-arc welding machine (LINCOLN DC-600). This outcome reveals that when this method is applied to weld flat steel (thickness<=6.5mm), the welding velocity can at least increase by 30%. Even when flat steel (thickness<=9.5mm) has no groove, the penetration is still sufficient.

This method is also successfully applied to the petroleum tank welding, increasing welding current by 15% while keep the welding quality sufficient.
