AWS A5.6 ECu
Nqe lus piav qhia: T107 yog tooj liab electrode ntshiab nrog cov tooj liab ntshiab raws li cov tub ntxhais thiab them nrog qis-hydrogen sodium hom flux.Siv DCEP (direct tam sim no electrode zoo).Cov khoom siv zoo, zoo corrosion kuj rau huab cua thiab dej hiav txwv, tsis haum rau vuam oxygen-muaj tooj liab thiab electrolytic tooj liab.
Daim ntawv thov: Nws yog tsuas yog siv rau vuam cov khoom siv tooj liab xws li cov khoom siv tooj liab, tooj liab kub exchangers, thiab seawater conduits rau nkoj.Nws kuj tseem tuaj yeem siv rau saum npoo vuam ntawm cov pa roj carbon steel qhov chaw tiv taus seawater corrosion.
Tshuaj muaj pes tsawg leeg ntawm weld hlau (%):
| Cu | Si | Mn | P | Pb | Fe+Al+Ni+Zn |
| 9 5.0 | ≤0.5 | ≤3.0 | ≤ 0.30 | ≤ 0.02 | ≤0.50 |
Mechanical zog ntawm weld hlau:
| Cov khoom kuaj | Tensile zog Mpa | Elongation % |
| lav | ≥170 | ≥ 20 |
Pom zoo tam sim no:
| Qws txoj kab uas hla (mm) | 3.2 | 4.0 | 5.0 |
| VuamTam sim no (A) | 120-140 ib | 150-170 Nws | 180-200 Nws |
Daim ntawv ceeb toom:
1. Cov electrode yuav tsum tau ci ntawm li 200 ° C rau 1 teev ua ntej vuam, thiab cov dej noo, roj, oxides thiab lwm yam impurities nyob rau saum npoo ntawm lub vuam yuav tsum tau muab tshem tawm.
2. Vim yog thermal conductivity ntawm tooj liab, thiab lub preheating kub ntawm cov ntoo yuav tsum welded yog feem ntau kuj siab, feem ntau yog siab tshaj 500 ° C.Qhov loj ntawm qhov vuam tam sim no yuav tsum sib haum nrog qhov kub thiab txias ntawm lub hauv paus hlau;Sim ntsug luv arc vuam.Nws tuaj yeem siv rau reciprocating linear motion los txhim kho weld tsim.
3. Rau qhov ntev welds, sim siv txoj kev rov qab kauj ruam vuam, thiab qhov vuam ceev yuav tsum ceev li sai tau.
Thaum welding ntau txheej, slag ntawm txheej yuav tsum tau muab tshem tawm tag nrho;Tom qab vuam, rauj lub vuam nrog lub taub hau rauj kom txo tau kev ntxhov siab,
Txhim kho weld zoo.
