Thaum phau ntawv hluav taws xob arc vuam cuam tshuam rau lub kaum sab xis ntawm kev tiv thaiv ntawm vuam loj, yog tias tsis nyob rau hauv cov txheej txheem vuam ib txwm tuav lub kaum sab xis kom raug, yuav ua rau muaj kev phom sij rau sab nraud, tsis muaj qhov nce ntawm qhov tseeb vuam seam ntev, yuav tsim. ib strip vent.Thaum cov theem ntawm txoj kab uas hla loj yog tsau rau tag nrho txoj hauj lwm vuam taub hau rau vuam, vim qhov siab yog li ntawd tus welder yuav tsum coj lub vuam txoj hauj lwm sib txawv ntawm ntau txoj hauj lwm nyob rau hauv thiaj li yuav tswj lub lag luam ntawm lub kaum sab xis bar.Nyob rau hauv oblique oblique tiaj welding thiab overhead vuam txoj hauj lwm, welder nyob rau hauv posture nyuaj, nws yog ib qho nyuaj rau tuav lub kaum sab xis tuav xa, yog li cov weld cov chaw no nquag mus strip qhov.Cov kab me me ntawm cov yeeb nkab vuam tsis zoo tshwm sim feem ntau vim yog lub txee erection tsis zoo tagnrho.Kev thauj mus los ceev thiab viav vias txiav txim siab lub thickness ntawm ib lub hlaws, xa tawm ceev ceev ua rau cov electrodes yuav tsum tau hloov lub kaum sab xis sai, lossis tsis tuaj yeem tsim cov slag zoo = roj sib koom ua ke tiv thaiv.Tom qab qhov qis-walled tube vuam yuav tsum npog nyias, tes vuam yuav tsum ceev thauj ceev, yuav muaj qhov strips.

Kev nkag tsis tiav

Fin tube welded pob qij txha yuav xav nyob rau hauv ib tug kab counterpart, ntxiv rau welding shrinkage deformation, ua nyob rau hauv ntau nyuaj rau tswj kom zoo clearance counterparts, thaum welding backing ntawm melting degree bevel tsis muaj zog, ua rau tsis muaj kev nkag mus.Stainless hlau welding consumables molten hlau ntws tsis zoo, thiab lub tshav kub sai sai, lub tshav kub tsis yog yooj yim mus mloog, uas ua rau lub arc cua sov thiab melting ntawm lub hauv paus hlau los yog weld hlau yog nyuaj rau sau, tsim ntawm incomplete nkag mus rau qhov tsis xws luag. .Feem ntau loj txoj kab uas hla tuab phab ntsa yeeb nkab, cov pob qij txha thaum vuam rov qab yog tias tsis muaj hauv paus nkag mus, yog tshwm sim los ntawm tsis muaj kev nkag mus;loj txoj kab uas hla tuab-walled raj blunt ntug yog loj, yuav ua rau tsis tiav nkag.

Slag

Thaum soldering, lub thickness ntawm cov hlau muab tub lim yuav cuam tshuam rau lub slag floating overflow, slag defects tsis tuaj yeem overrun yog tias lub slag tsim.Loj txoj kab uas hla tuab-walled yeeb nkab vuam feem ntau yog siv thaum lub sij hawm loj tam sim no, qhov loj dua thickness ntawm ib leeg-dhau vuam slag kiag li floating ntau nyuaj los tsim ib tug slag defects.Liquidity muab tub lim hlau slag muaj kev cuam tshuam zoo rau lub cim ntawm qhov tsis xws luag.Cov khoom siv stainless hlau ntawm cov hlau molten tsis muaj zog, ua ke nrog kev siv me me tam sim no nqaim weld ua haujlwm, cov hlau weld solidification, nyuaj rau tag nrho nto weld slag, slag tsim ntawm qhov tsis xws luag.Kab rov tav welding, soldering oblique vuam lub taub hau txais txoj kab, txoj kab xov tooj raws li kev tswj tsis zoo, tuaj yeem ua rau weld "tuag", muaj feem ntau dua ntawm slag defects.

Txhaum

TIG ntaus hauv qab li nyias, kev ntxhov siab yuav ua rau nws tshwm sim thaum sau kua muag los ntawm kev tsim cov kab nrib pleb;tsis raws sij hawm sub-layer backing weld tom qab vuam, tab sis kuj ua rau tawg.Preheat qhov kub thiab qhov tsis zoo vuam pas nrig cia, siv tsis raug, yuav ua rau muaj kev tawg.
