Dab tsi yog qhov toughest hlau rau weld

Aluminium. Thawj qhov kev xav ntawm txhuas yog tias nws hloov tau yooj yim thiab yooj yim rau kev ua haujlwm nrog, ua rau nws yooj yim rau vuam. Tab sis nyob rau hauv kev muaj tiag, aluminium yog suav hais tias yog cov hlau nyuaj tshaj plaws rau welding vim nws yog ib qho alloy.

Puas yog Corten steel nyuaj rau vuam?

Weathering steel yog cov hlau alloy uas muaj zog zoo heev. Nws cov tshuaj muaj pes tsawg leeg ua rau nws tiv taus corrosion los ntawm huab cua thiab atmospheric tej yam kev mob (xws li huab cua thiab noo noo). Nws tsim kev tiv thaiv, xim zoo li oxide txheej (hlau oxide lossis xeb) hu ua "patina" ntawm nws qhov chaw, ua rau nws tiv taus corrosion. Nws tsuas yog tsim xeb ntawm sab nrauv. Cov txheej txheej saum npoo no tsis tso cai rau cov xeb nkag mus tob rau hauv cov huab cua hlau, yog li tiv thaiv corrosion.
Weathering steel tseem hu ua weathering steel. Nws tau sau npe nyob rau hauv lub cim lag luam Cor-Ten, uas yog thawj zaug tsim thiab patented los ntawm US Steel nyob rau hauv 1933.Cor-Ten muab nws lub npe los ntawm ob lo lus - corrosion kuj thiab tensile zog. Txawm li cas los xij, American Society for Testing and Materials (ASTM) tom qab ntawd tau tsim nws raws li cov khoom lag luam.

Welding ntawm Corten steel yog qhov zoo ib yam li cov hlau me me. Tib yam uas tus welder yuav tsum paub txog yog cov muab tub lim lossis electrode, uas txawv ntawm cov hlau me me.
