b.Indlela yesilika yangaphandle

Okokuqala, lungiselela kwangaphambili i-arc yesixa socingo lwe-welding, emva koko ulungise umlomo we-welding welding kwi-engile ye-weld ye-engile ye-60 °, qalisa i-arc, kwaye ubeke ingqalelo kwimeko yokutyisa ucingo lwe-arc kunye ne-pool etyhidiweyo. kwilensi.

Ucingo lunokondliwa ngokuqhubekayo okanye ngokuphazamiseka kwe-arc. Ukubonakaliswa kwelensi kunokulahlekisa ngokulula ukusebenza: umzekelo, kunzima ukwahlula phakathi kocingo lwewelding kunye nocingo lokuwelda olubonakaliswe kwilensi, olunokuthi lukhokelele ngokulula ekungondlekiyo kocingo, ubushushu obugqithisileyo bechibi elinyibilikisiweyo, kunye nomonakalo i tungsten. Ngokugqithisileyo, iziphene ezifana ne-pores kunye nokudandatheka kubonakala.

Ke ngoko, ukusebenza kukuzinikela kwisiboniso sesibuko, kwaye ngokuqaphela uhoye i-arc curvature ye-welding wire kwi-groove ukondla ucingo ngokulinganayo. Umpu we-welding usetyenziswa ngokusebenzisa indlela "ezimbini ezicothayo kunye neyodwa ngokukhawuleza", kwaye i-angle ye-welding gun ilungiswa ngokwe-arc kwi-lens.

Gwema ukuthobisa umpu we-welding kakhulu, okwenza ukuba i-arc ibe yinde kakhulu kwaye isiseko sesiseko sibe sikhulu kakhulu, ukukhusela iziphene ezifana nokungena okungaphelelanga. Xa i-welding iphakathi kwe-8 kunye ne-9 intsimbi, inxalenye ye-arc yangempela ingabonwa, kwaye umsebenzi unokudibaniswa kunye nemeko yangempela kunye nesibuko sobuso.

Gqibezela i-1/4 yomlomo wombhobho weld kwaye uqalise ukuwelda kwesipili kwenye i-1/4 ye-weld. Umdibaniso kwindawo yentsimbi yesi-6 yenye yemisebenzi ebalulekileyo ye-mirror welding, kwaye iziphene zinokwenzeka ukuba zenzeke ngexesha lokusebenza umva.

Ngexesha lokusebenza, ukuqinisekisa umgangatho wokudibanisa, i-arc kufuneka itshiswe malunga ne-8 ~ 10 mm ye-weld yangaphambili ye-joint, kwaye ke i-arc kufuneka iziswe ngokuthe gqolo kwi-joint ye-weld yangaphambili ngentsimbi yesi-6. . Xa i-pool etyhidiweyo yenziwe kwi-joint Emva koko yongeza ucingo lwe-welding ukwenzela ukusebenza kwesipili esiqhelekileyo.

Ekugqibeleni, gcwalisa i-primer welding kwicala langaphambili (i-non-mirror welding) ngokulandelelana kwi-Figure 2, kwaye ukutywinwa kugqityiwe.

(2) Isigqubuthelo sokuwelda

1) Uhlalutyo lobunzima

Ngenxa yokuba indawo ye-weld kwisibuko ichasene neyona nto yokwenene, kulula ukubangela i-undercuts, imiphetho engaxutywanga ye-grooves, iileyile zangaphakathi ezingaxutywanga, iipores, okanye umonakalo kwi-electrode ye-tungsten ngexesha lokusebenza.

2) Iimfuno zokusebenza kwe-welding

sdf (5)

Ngaphambi kwe-welding, i-trajectory ye-welding gun kufuneka ifaniswe, kwaye i-angle ye-lens kunye ne-arc curvature yesixa esilungiselelwe ngaphambili socingo lwe-welding kufuneka lulungiswe.

Ngethuba lokusebenza kwe-welding, kufuneka uqale ulungelelanise umlomo we-welding gun kwindawo ye-6 yentsimbi ye-groove kwi-angle ye-60 ° ye-arc preheating. Emva kokufudumala, kunye nokukhanya kokukhanya kwe-arc, yandisa ucingo lwe-welding yangaphambili ukusuka kwicala lombhobho ukuya kwindawo yokutshisa i-arc kwi-lens. Isikhundla, ucingo feed. Eyona ndlela ilungileyo yokulutha ucingo kukuhuka intambo yokuwelda nge-arc curvature kumthungo wokuwelda wombhobho, ukondla ucingo ngokucothayo ngokuqhubekayo nangokulinganayo kwidama elityhidiweyo, kwaye ujonge ukukhula komphetho we-welding seam kunye nokutshintsha amathontsi atyhidiweyo kwilensi. inkqubo kunye nobude be-arc yencam ye-tungsten electrode,

Ngokwendlela yokuwelda "ezimbini ezicothayo kunye enye ekhawulezayo", hamba uye kwindawo yentsimbi yesi-9 kwindawo yesipili ukuze ugqibezele i-1/4 yokugubungela umphezulu we-welding kwaye ucime i-arc. Emva koko uhambise i-lens kwenye i-1/4 ye-weld yangasemva ukwenzela ukulungiswa kwe-trajectory ukulinganisa kunye nokulungiswa. Ukusebenza okungafanelekanga kwe-interface kwiindawo ezi-6 kuya kubangela iziphene ze-welding, kwaye licandelo elixineneyo apho kwenzeka khona iziphene.

Kungcono ukuqalisa ukufudumeza kwe-arc kwi-weld yangaphambili ngentsimbi yesi-6. Xa i-joint inyibilika kwi-pool etyhidiweyo, yongeza ucingo lwe-welding ukwenza umsebenzi oqhelekileyo we-mirror welding. Nika ingqalelo kwimeko yokunyibilika komphetho kwaye ulandele indlela yokuqala ye-1/4. Sebenza de i-arc iphume ngentsimbi yesi-3 kwaye iyeke.

Emva koko weld inxalenye edityanisiweyo ngokweendlela eziqhelekileyo ukugqiba isigqubuthelo umaleko welding yombhobho wonke.

5. Izilumkiso

①Izakhono zokubeka isipili zibaluleke kakhulu. Ukude i-lens isuka kwinto eyiyo okanye i-parallel engaphantsi kwi-into yokwenyani, ukuchaneka okukhulu komsebenzi kuya kuba;

② Okukhona i-lens kunye nento isuka kumqhubi, kokukhona kuya kuba nzima ukusebenza;
