Cov yam ntxwv thiab kev siv
AWS A5.20 E70T-7Flux CoredArcVuam Hlauyog ib tug self-shielded flux cored hlau tsim rau siab nkag welding.Nws yog qhov tsim nyog rau txoj haujlwm tiaj tus, kab rov tav thiab nqes toj ntawm DCEN polarity.Kev ua tau zoo heev ntawm kev kuaj X-ray, thiab desulfuration txo qhov tawg hauv vuam tuab daim hlau, txwv cov pob qij txha thiab nruab nrab-carbon steel.Qhov raug
daim ntaub ntawv yog dav fabrication thiab structural weldment qhov twg siab deposition nrog zoo nkag thiab kuv los yog ceev ceev mus txawv tebchaws yuav tsum tau.Cov hauj lwm muaj yog tiaj weld, kab rov tav weld thiab ntsug down ones of welding for fllet weld and lap joint.

Cov lus qhia rau kev siv:
1.DC(-) polarity raug pom zoo.
2. thaum cuam tshuam toughness ntawm weld hlau yog qhov tseem ceeb.
3. Khaws cov khoom kom qhuav, thaum nws khaws cia lossis xa khoom.
