Ukulungiswa kwe-Roll Submerged Arc Welding
Roll ukulungisa ukuwelda kwe-arc yindlela yokudibanisa i-arc eyomeleleyo ye-welding, yendalo kwinkqubo ye-welding ayikwazi ukubona i-arc, kwaye ininzi ye-welding ezenzekelayo, iimeko zabasebenzi ziphuculwe kakhulu.Ukuwelda kwe-arc emanzini, umgaqo wokukhetha ukucaciswa kwe-welding kukuba: ukuqinisekisa i-arc evuthayo ezinzileyo, imilo ye-weld kunye nobukhulu ukuhlangabezana neemfuno, umphezulu wenziwa ngokugudileyo kwaye ucocekile, akukho pores yangaphakathi, i-slag, iintanda, i-weld tumor kunye nezinye. iziphene.Iindlela zokukhetha eziqhele ukusetyenziswa yindlela yetafile, indlela yovavanyo, indlela yobungqina, indlela yokubala.Kungakhathaliseki ukuba yeyiphi indlela esetyenziselwa ukumisela iiparitha, kufuneka ilungiswe ekusetyenzisweni kwe-welding, ukufezekisa eyona nto isebenzayo xa i-welding iqhubekayo.
Ngokoluhlu olusebenzayo lwangoku lwe-monofilamentUkuwelda kwe-arc emanzini, xa ubukhulu beplate bungaphantsi kwe-14mm, awukwazi ukuvula i-bevel, indibano kunye nesithuba esithile;ubukhulu bepleyiti 14 ~ 22mm, vula ngokubanzi i-bevel emile okwe-V;ipleyiti ubukhulu 22 ~ 50mm, vula X-emilise bevel;kwibhoyila gas ladle kunye nezinye iinqanawa zoxinzelelo ngokuqhelekileyo zisebenzisa U-shaped okanye kabini U-shaped bevel, ukuqinisekisa ukuba umaleko ezantsi weld ngokusebenzisa kunye nokuphelisa slag.Iindlela zokusetyenzwa kwe-bevel zihlala zisebenzisa umatshini wokucwangcisa umda kunye nomatshini wokusika igesi, kufuneka kubekho inqanaba elithile lokuchaneka kokusebenza.Ukudibanisa okuthe tye kufuneka kufakwe kwiiphelo zombini ze-arc-priming plate kunye ne-arc-extinguishing plate, ukwenzela ukunciphisa i-arc-priming kunye ne-lead-out defects.
Kuba indawo ukuwelda emva iinxalenye welding, ngokubanzi ukwandisa ubushushu ukusebenza okanye sandblasting kunye nezinye iindlela ukuqinisekisa umgangatho welding.
In ukuwelda kwe-arc emanzini, ngokuqhelekileyo kuyimfuneko ukuhlengahlengisa i-welding yangoku kunye nokulinganisa i-arc voltage ngokuzenzekelayo.Izinto ezichaphazela i-welding current zezi: ubukhulu beplate, isantya se-welding, i-wire diameter, njl.
Itekhnoloji yeWelding yokuwelda i-butt straight seam
Iindlela ze-welding ze-butt straight seam welding zezi: i-welding-sided welding kunye ne-double-side-side welding;i-welding eyodwa-layer kunye ne-multi-layer welding;indlela ye-liner pad kunye ne-linerless method.Indlela ye-Flux pad entywiliselwe i-arc ye-welding ezenzekelayo, oko kukuthintela ukuvuza kwe-slag kunye nesinyithi se-pool etyhidiweyo, ukusebenzisa inkcazo ye-welding enkulu kukungena kwe-weld ukuphumeza ukubunjwa kwamacala amabini.I-welding manual capping submerged arc automatic welding, ye welding seams engakwaziyo ukusebenzisa iliner, inokuqala i-welding manual capping kwaye emva koko.ukuwelda kwe-arc emanzini.Welding Overhead, ngokuba akukho bevel, akukho umsantsa butt welding, akasebenzisi naziphi na iimfuno umsantsa indibano liner zingqongqo kakhulu.Ukuze kuqinisekiswe ukuba ukungena kwe-weld, ukuwelda kwangaphambili ukuwelda nge-40 ukuya kwi-50%, i-welding ngasemva kufuneka iqinisekise ukuba ukungena kwe-weld ye-60 ukuya kwi-70%.Ngokuziqhelanisa ngokuqhelekileyo kunzima ukulinganisa ubunzulu bokunyibilika, ngokuqhelekileyo ngokuqwalasela umbala womva wedama elityhidiweyo ukugweba nokuqikelela, ukuze ube namava athile.I-Multi-layer submerged arc welding, ipleyiti yentsimbi eshinyeneyo ukusebenzisa i-welding multi-layer, i-welding ephantsi yenkcazo ye-welding ibe yincinci, zombini ukuqinisekisa ukuba ukungena kwe-weld, kodwa nokuphepha ukuqhekeka kunye nezinye iziphene.Umaleko ngamnye we-weld joints kufuneka ugxadazwe ukuze ungadibani.
Butt ring umthungo welding iteknoloji
Iukuwelda kwe-arc emanzini Umthungo we-butt ring ye-cylinder cylinder kufuneka yenziwe ngevili elijikelezayo elinesixhobo sokulawula isantya.Ukuba i-welding ephindwe kabini iyafuneka, i-pad ye-flux kufuneka ibekwe kwi-weld yangaphandle ye-cylinder engezantsi kwi-pad yokuqala.Lungisa i-welding trolley kwisakhelo se-cantilever kwaye ufikelele ezantsi kwi-barrel ukuze weld flat.I-Weld wire offset centerline phantsi kwendawo ye-welding ye-slope.I-welding yesibini yangaphambili yenziwa ngaphandle kombhobho, kwi-welding ephezulu yeflethi.
Itekhnoloji ye-welding edibeneyo
Kwimidibaniso ye-T kunye ne-lap joints, iindlela ezimbini zokuwelda okumilise okwenqanawa okanye ukuwelda i-angle ye-bevel zisetyenziswa ngokubanzi, kunye ne-flat angle welding, i-angle phakathi kocingo kunye newebhu igcinwe kakuhle kwi-20 ukuya kwi-30.°
Ukuntywiliselwa kwe-arc semi-automatic welding
Ukuwelda kwe-arc semi-automatic entywilayo kusetyenziswa ngokubanzi ngocingo olungaphantsi kwe-2mm, ikakhulu kwi-welds ye-fillet, kodwa kunye ne-butt welds.
