1, you are the tank, it should be said that the pressure is not too much, directly with the electrode arc welding can be, the choice of A022 electrode, should be open bevel, the bottom layer of welding should be applied after the carbon arc gas planer or grinding wheel to clear the root of the weld, regardless of whether to open a single-face bevel or double-face bevel, contact with the S02 solution of the cover layer of the weld should be the last weld.
2, the electrode's chromium, nickel content is a little higher than the base material is possible, but too high will increase the cost.
3, alloy steel welding material selection is to match the chemical composition, can not be low.
4, 16mm thick plate welding without argon arc welding, to clear the welding root.
5, there is no need to use a separate argon arc welding, low efficiency, increase costs.
