#Ferrosilicon 1-4 molybdenum-iron 1.5-3
When using welding rod of the present invention, needn't be to the workpiece preheating of going ahead of the rest, just can directly weld pearlite heatproof steel, and form deposited metal in the welding position with Ultra-low carbon, ultralow hydrogen composition, the chemical composition content of this deposited metal is stable, and this deposited metal has higher impact flexibility, has excellent cracking resistance, therefore, can not produce weld crack in the welding position.
Compared with the prior art the present invention has following advantage:
1, can improve preheating, insulation and the slow cooling welding procedure of existing pearlite heatproof steel, significantly reduce the time of back work, improve working (machining) efficiency.
Workpiece is in the normal temperature state when 2, welding, and has exempted the baking of high temperature, has improved workman's working condition.
3, needn't heat for a long time preheating, energy savings in a large number of Han Jie workpiece.
4, the deposited metal that forms of the present invention has higher impact flexibility, has excellent cracking resistance, has improved welding quality greatly.
5, owing to the preheating of having exempted workpiece, can site operation, the expense of reduction maintenance greatly to repairing in the equipment repair welding of usefulness.
