What kind of welding rod is used for Q345R steel plate welding?
With the E5015 DC reverse connection, if the AC welding machine is E5016, the electrode diameter and welding current shall be selected according to the thickness of the plate.
Vessel steel, with wide application range of J506R (E5016) welding, the weather is not good now, less than 15 degrees should pay attention to insulation, preheating, don't let the weld cold air humidity is greater than 70% or no end of trouble for the future, is to do the drying (electrode, weld must be cleaned before welding, final note)
Q345R is an ordinary low alloy steel. It is commonly used in boiler and pressure vessel. The delivery status is hot or normalized, low alloy steel. The performance is similar to that of Q345 (16Mn) (the yield strength of 16mm steel plate is greater than 345Mpa), the tensile strength is (510-640), the elongation is greater than 21%, and the impact strength of zero V is greater than 34J. E5015 calcium electrode is recommended.
