Applications
ES 10018 -GV t is particularly used for welding tempered steels having high yield strength values. Therefore, it is recommended in applications when preheating cannot be applied. It can be used in all position and in all types of joints. It is particularly used in the welding of steel parts, boiler and pressure vessels and in construction of heavy machinery that operate under difficult conditions like dynamic loads and very high or low operating temperatures.
