1. Yog hais tias qhov sib txawv loj heev, cov nyhuv nyob ze yuav raug txo, qhov kub ntawm lub vortex tsis txaus, thiab cov vuam seam crystals yog indirectly ua ke nrog molten los yog tawg.
2. Yog tias qhov sib txawv me me dhau, qhov cuam tshuam ntawm cov neeg nyob sib ze yuav nce, qhov vuam kub loj dhau, ua rau vuam seams puas; los yog cov welding seams yog squeezed thiab dov los ua ib tug sib sib zog nqus pit, uas cuam tshuam rau qhov zoo ntawm lub welding.
Tom qab cua sov ob npoo ntawm lub raj billet mus rau qhov kub thiab txias, nyob rau hauv lub nyem ntawm cov squeezing cov menyuam, cov hlau nplej ntau nkag mus thiab crystallize, thiab thaum kawg tsim ib tug ruaj welding seam. Yog hais tias lub siab ntawm cov kauv steel yeeb nkab me me dhau lawm, tus naj npawb ntawm cov khoom siv lead ua yuav me me, qhov kev siv ntawm cov hlau hlau ntawm cov welding yog txo, thiab nws yuav tawg tom qab lub zog; yog tias lub siab loj dhau lawm, cov hlau ntawm lub xeev melting yuav raug nyem tawm ntawm qhov vuam. Tsis tsuas yog txo qhov kev siv ntawm welds, tab sis nws kuj yuav tsim ib tug loj npaum li cas ntawm sab hauv thiab sab nraud burrs, thiab txawm yuav ua rau tsis xws luag xws li vuam seams.
Tsis tsuas yog nws yuav tsum tau welded, tab sis kuj cov welds sab hauv thiab sab nraud yog 1-3 hli. Lub kaum sab xis ntawm kauv raj weld feem ntau yog 50-75 degrees, yog li qhov kev ntxhov siab hluavtaws ntawm cov kauv vuam yog 60-85 % ntawm qhov kev ntxhov siab tseem ceeb uas ncaj qha welded. Nyob rau hauv tib lub zog ua hauj lwm, lub kauv raj nrog tib lub raj yog txo los ntawm ncaj welding ntawm phab ntsa thickness.
Nyob rau hauv tus txheej txheem ntawm kev tsim, cov yeeb nkab steel yog uniformly deformed, residual kev nyuaj siab yog me me, thiab nto tsis tsim khawb. Cov txheej txheem muab kauv steel kav muaj qhov yooj yim dua nyob rau hauv qhov loj thiab specification ntau ntawm txoj kab uas hla thiab phab ntsa thickness.
Kauv steel kav yuav siv tau rau kev thauj mus los ua kua: dej ntws. Nws tuaj yeem siv rau kev thauj mus los ntawm ntuj: roj, nkev, roj av liquefied. Nws tuaj yeem siv rau cov qauv: pawg tube, kab teeb, docks, txoj kev thiab architectural lug.
