Ceev faj rau Vuam Ntawm Cov Yeeb Nkab Hlau

1. Txheeb xyuas qhov kev ntxhov siab, deformation, yooj yim ntawm kev khiav lag luam, thickness ntawm lub vuam, vuam txoj hauj lwm thiab txoj kab uas hla ntawm electrode los npaj cov groove sib thooj.

2. Siv cov nplaim hluav taws kub hnyiab ntawm ob sab ntawm qhov yuav tsum tau welded, kom tag nrho cov roj uas nkag mus rau sab nraud ntawm lub hauv paus lub cev yog volatilized kom txog thaum tsis muaj pa taws.

3. Thaum vuam, lub arc yuav tsum qis, lub arc yuav tsum tau nias sai sai kom tsis txhob muaj arc, thiab lub arc yuav tsum tsis txhob dhia mus rau sab laug thiab txoj cai kom lub vuam zoo nqaim thiab txo qhov thermal stress cheeb tsam, uas yuav ua rau cov hlau ductile. yeeb nkab kev sib txuas siab.

4. Siv luv luv arc thiab luv seam vuam, thiab qhov ntev ntawm vuam seam yuav tsum tsis txhob 60 hli; txais kev sib tshuam segmented vuam, weld ib qho kev ncua deb, thiab tom qab ntawd weld seem tom ntej; txais yuav qhov kub ntawm ntau txheej txheej vuam txheej los tswj ntawm 60 ~ 80 degree, thiab sim ua cov txheej tom ntej ntawm vuam seam ntawm fusion kab ntawm yav dhau los txheej ntawm vuam seam; tshuaj xyuas nws nyob rau lub sijhawm thaum vuam, yog tias koj pom qhov pores, slag inclusions, welding lumps, thiab lwm yam, koj yuav tsum tam sim ntawd zom cov vuam los ntawm tes sib tsoo los ntxuav lub vuam ua ntej vuam txheej tom ntej. txheej.

5. Thaum lub weld yog liab thiab kub, coj mus rhaub lub weld nrog ib tug me me rauj kom txog rau thaum lub weld yuav tsaus ntuj nti, dov tawm lub weld, so lub siab thiab nyem lub stingy qhov, thiab nyob rau tib lub sij hawm kho cov nplej nyob rau hauv weld cheeb tsam. .
