What type of welding rod is applied to Q345 steel plate?
Q345 steel plate is welded with J506 or J507 electrode.J506 is a low hydrogen potassium electrode, it is a kind of basic electrode, welding steel structure and the typical Q235, Q245R, Q345 steel, the tensile strength of E4315 is much larger relative to the common electrode, so the general welding force or by welding steel structure of dynamic load.J506 welding rod diameter ranging from 2.5mm to 6.0mm, can be carried out in all position welding, welding using alternative welding machine.The weld formation after J506 welding is more difficult than that of the acid welding rod. If an electrode is used on the cover of the steel structure, the acid electrode can be used.J507 is a low sodium hydrogen electrode, it is a kind of basic electrode, can be Q235, Q245R, Q345 typical welding structure steel in steel, the tensile strength of E4315 is much larger compared to the common electrode, so the general welding force or under dynamic load of steel structure.J507 welding rod diameter ranging from 2.5mm to 6.0mm, can be carried out in all position welding, welding using DC welder, polarity reversal. Of course, if there is only AC welder in the field, AC welder can be used, but the current needs to be switched on.The weld formation after J507 welding is more difficult than that of the acid welding rod. If an electrode is used on the cover of the steel structure, the acid electrode can be used.
E50 series (E5001~E5048) welding rod can be. To adapt to the requirements and welding of steel used in SMAW electrode, using the intensity principle of E50 series E55 series above right above strength, high cost, comprehensive strength and economic aspects, should choose E50 series of electrode.
