Weld yeeb nkab weld porosity cuam tshuam tsis tsuas yog cov kav dej ntom ntom, uas ua rau cov kav dej xau thiab xeb yuav raug cuam tshuam los txo qhov vuam lub zog thiab toughness.Cov yam ntxwv ntawm weld porosity yog: lub flux nyob rau hauv dej, av, oxide thiab hlau filings, vuam cov khoom xyaw thiab npog thickness, nto zoo steel thiab steel sab phaj ua, vuam technology thiab steel molding txheej txheem.

Cov kev tiv thaiv ntsig txog:

1. Flux cov khoom xyaw.CaF2 thiab SiO2 uas muaj qhov tsim nyog ntawm vuam, cov tshuaj tiv thaiv yuav nqus cov H2 ntau, ua kom muaj kev ruaj ntseg ntawm HF insoluble hauv cov kua hlau, yog li tiv thaiv kev tsim ntawm hydrogen gas qhov.

2. Lub thickness ntawm cov flux feem ntau yog 25-45mm, loj solder particle loj, bulk ntom teev coj lub siab tshaj plaws thickness, whereas qhov tsawg kawg nkaus tus nqi;siab tam sim no, tsis tshua muaj vuam ceev tsub kom lub siab tshaj plaws thickness, whereas qhov tsawg kawg nkaus tus nqi ntxiv, lub caij ntuj sov los yog huab cua humidity, flux rov qab yuav tsum tau qhuav ua ntej siv.

3. Cov ntawv kho deg-kho steel.Txhawm rau kom tsis txhob qhib phau ntawv theem tawm oxide nplai thiab lwm cov khib nyiab rau hauv cov txheej txheem molding, lub rooj tsavxwm yuav tsum tau teeb tsa cov cuab yeej tu.

4. Steel phaj ntug ua.Hlau phaj ntug yuav tsum tau teem xeb thiab burr tshem tawm cov cuab yeej kom txo tau qhov tsim ntawm qhov.Tshem tawm cov cuab yeej nruab rau hauv txoj haujlwm zoo tshaj plaws tom qab lub tshuab milling thiab disc shear, cov qauv ntawm cov cuab yeej yog lub zog hlau log sab ob sab thiab nqes txoj hauj lwm adjustable qhov sib txawv, sab sauv thiab qis clamping phaj ntug.

5. Weld profile.Weld forming factor yog me me dhau, nqaim thiab sib sib zog nqus weld zoo, roj thiab kev suav nrog tsis yooj yim rau xau tawm, yooj yim rau daim pores thiab slag.General weld coefficient tswj nyob rau hauv 1.3-1.5, tuab-walled yeeb nkab siab tshaj tus nqi, yam tsawg kawg nkaus tus nqi ntawm nyias-walled.

6. Txo cov hlau nplaum thib ob.Txhawm rau txo qhov cuam tshuam ntawm cov hlau nplaum yuav tsum tau ua rau ntawm qhov chaw ua haujlwm welding cable txuas qhov chaw tsuas yog ua tau deb ntawm lub vuam davhlau ya nyob twg, kom tsis txhob muaj qee qhov vuam cable thib ob magnetic teb generated hauv workpiece.

7. Kev ua haujlwm.Yuav tsum tsim nyog los txo lossis nce qhov ceev ntawm qhov vuam tam sim no, yog li ncua lub crystallization tus nqi ntawm lub vuam hlau da dej kom yooj yim rau kev khiav tawm ntawm cov pa roj, tib lub sijhawm, yog tias cov sawb xaim qhov chaw tsis ruaj khov, yuav tsum tau hloov kho raws sijhawm. tshem tawm cov kev nplua ntau zaus tom qab kev saws me nyuam ntawm lub qag pem hauv ntej los yog choj kom tswj tau cov molding, ua rau cov pa roj kom dim nyuaj.
