Description

A kind of control method of submerged-arc welding deposited metal phosphorus content
Technical field
The present invention relates to a kind of buried arc welding method, belong to a kind of control method of submerged-arc welding deposited metal phosphorus content particularly.
Background technology
Phosphorus in weld seam is one of main harm element.Especially in the weld seam of the welding such as nuclear power structure, high-performance pipeline, the content requirement of phosphorus is strict, but in actual welding, want the Forecast and control of the content of P in submerged arc weld very difficult again, its reason be submerged-arc welding use welding wire and solder flux be welding material, in welding process, welding wire and solder melts form molten bath, molten pool metal carries out complicated metallurgical reaction, along with a series of de-P process, main as following various:
2[Fe 2P]+5(FeO)→P 2O 5+9[Fe]，P 2O 5+3(CaO)→(CaO)3·P 2O 5，P 2O 5+4(CaO)→(CaO)4·P 2O 5。

P seam=(2/3P silk+ 1/3P agent)+0.001 (ln0.010/P silk+ ln0.020/P agent)
In formula: P seamthe weight percent content of-expression submerged-arc welding deposited metal phosphorus,
P silkthe weight percent content of phosphorus in-expression welding wire,
P agentthe weight percent content of phosphorus in-expression solder flux;
3) according to step 2) in the submerged-arc welding deposited metal phosphorus P that predicts seamvalue, determines concrete containing P welding wire and solder flux; As predicted submerged-arc welding deposited metal phosphorus P seamwhen value meets the requirements, then the welding wire containing P used and solder flux are then as welding wire during actual welding and solder flux; As predicted submerged-arc welding deposited metal phosphorus P seamwhen being worth undesirable, then continue to select, until meet the requirements.
It is: selected solder flux before use, will toast 1.5 hours under 350 DEG C of conditions.
Calculating formula of the present invention through being verified in laboratory, adopt the welding wire of different P content select and solder flux weld, the weld seam P content of PREDICTIVE CONTROL and experiment results identical; Through verifying further in engineering welding test, measured value is equally comparatively identical, obtains good result.
The present invention compared with prior art, pass through set up calculating formula, strictly can control submerged arc weld P content, fast, accurately can select again the phosphorous welding wire and solder flux that mate, without the need to carrying out test apolegamy welding wire and solder flux, and the weld seam P content of PREDICTIVE CONTROL and experiment results are coincide; Through verifying further in engineering welding test, measured value is identical equally, obtains good result.
