Embodiment 1
[0039] The mass percentage of each component of the drug powder core is as follows: 4% ferroboron, 0.05% ferromolybdenum, 2.5% fluoride, 2.5% zircon sand, 4% magnesium powder, 2.5% quartz sand, 5% ferrosilicon, 14% electrolytic manganese , ferromanganese 2%, nickel powder 3%, metal chromium 3%, copper powder 2%, titanium ferro 3%, feldspar 0.5%, sodium titanate 4%, rutile 40%, and the balance is iron powder.
[0040] The composition of the carbon steel strip is: C: 0.025%, Mn: 0.22%, Si: 0.0082%, S: 0.0056%, P: 0.010%, Al: 0.018%, and N: 0.0023%, and the balance is iron and impurities.
[0041] Before mixing the components of the drug powder core, each drug powder is sieved with an 80-mesh sieve, then mixed evenly according to the proportion, placed on the steel sheath, wrapped or rolled into silk and drawn Flux-cored welding wire whose diameter is reduced to a predetermined specification.
Embodiment 2
[0043] The mass percentage of each component of the drug powder core is as follows: ferroboron 4%, ferromolybdenum 0.05%, fluoride 1.5%, zircon sand 1.5%, magnesium powder 4%, quartz sand 3%, ferrosilicon 5%, electrolytic manganese 12% , ferromanganese 4%, nickel powder 3%, metal chromium 3%, copper powder 2%, titanium ferro 3%, feldspar 2%, sodium titanate 4%, rutile 35%, and the balance is iron powder.
[0044] Other steps are the same as in Example 1.
Embodiment 3
[0046]The mass percentage of each component of the drug powder core is as follows: 4% ferroboron, 0.05% ferromolybdenum, 2.5% fluoride, 1.5% zircon sand, 4% magnesium powder, 3% quartz sand, 5% ferrosilicon, 14% electrolytic manganese , ferromanganese 2%, nickel powder 3.5%, metal chromium 3%, copper powder 2.3%, titanium iron 3%, feldspar 0.5%, sodium titanate 4%, rutile 37.5%, and the balance is iron powder.
[0047] Other steps are the same as in Example 1.
[0048] The weather-resistant steel flux-cored welding wire for coating-free bridge steels implemented in 1-3, when using DC reverse welding, the arc is stable, the spatter is small, the slag is easy to remove, the weld shape is beautiful, and it is suitable for all-position welding. The deposited metal composition was: C: 0.042%, Mn: 1.17%, Si: 0.24%, S: 0.0076%, P: 0.0089%, Cr: 0.42%, Ni: 0.55%, Cu: 0.36%. The mechanical properties of the deposited metal are: yield strength Rel: 510Mpa, tensile strength Rm: 590Mpa, e...
