Iingcebiso zokukhetha abashicileli beendawo
Ubukhulu be-welding
Xa ukhetha i-welder yendawo, ukuqwalasela ubukhulu be-welding kubalulekile. Ukujonga iinkcukacha ze-welder kunceda ukuqonda ukuba ifaneleke ngakumbi kwiintsimbi ezincinci okanye ezishinyeneyo.
Ubungqingqwa be-welding buchaphazela ubungakanani bangoku, i-voltage, kunye nexesha apho i-welder iyakufuna ukudibanisela amaqhekeza amabini ngokuchanekileyo. Isixhobo sokuwelda esinemveliso encinci sifanela ukuwelda kunye neentsimbi ezicekethekileyo, ngelixa i-spot welder enemveliso eninzi ifanela iintsimbi ezityebileyo.
Abasebenzisi ke ngoko kufuneka balumke kwaye bafumane kuphela a indawo yokuhambisa iyahambelana nobungqingqwa bentsimbi abayiluzayo. Ukukhetha i-welder engahambelaniyo kunokwenza i-weld arcs ekumgangatho ophantsi okanye yonakalise izinto zetsimbi.
Ukuphuma kwamandla
Isiphumo samandla sespot welder simisela ubukhulu bezinto ezinokuweld. Ukukhutshwa kwamandla aphezulu kuya kuvumela ukuwelda kwezixhobo ezityebileyo, ngelixa amandla asezantsi aphumayo aya kuvumela kuphela ukuwelda kwezinto ezincinci.
Kukwabalulekile ukuqwalasela iintlobo zemathiriyeli ezidityanisiweyo, njengoko ezinye izixhobo zinokufuna ukuphuma kwamandla aphezulu kunezinye. Ukongeza, ukuphuma kwamandla aphezulu kunokuncedisa ekuqinisekiseni i-weld ekumgangatho ophezulu kunye nokunciphisa umngcipheko wee-welds ezingalunganga. Ukukhetha i-welder yendawo kunye nemveliso yamandla efanelekileyo kubalulekile ukunceda abathengi bafezekise umgangatho we-welds.
lobushushu uluhlu
Xa ukhetha i-welder, kubalulekile ukuqwalasela uluhlu lobushushu bohlobo lwesinyithi olunokuweld. Umzekelo, i-welder enoluhlu oluphezulu lobushushu iyimfuneko ukuwelda iintsimbi ezomeleleyo njenge-titanium. Ngokwahlukileyo koko, a i-welder ngoluhlu olusezantsi lobushushu lufanelekile ukuwelda iintsimbi ezithambileyo ezifana nentsimbi engenasici. Ngaphezu koko, abasebenzisi kufuneka baqwalasele ubungakanani besinyithi kunye nokumila ukuqinisekisa ukuba ubushushu busasazwa ngokulinganayo xa bewelda.
Power umthombo
Uhlobo lomthombo wamandla osetyenziswayo luchaza ubungakanani kunye nomthamo wendawo umatshini wokuwelda ukuthenga. Umatshini onikwe amandla ngumthombo wamandla aphezulu-amperage uya kuba ne-welding yangoku eyomeleleyo kwaye ngaloo ndlela ube nomthamo ophezulu wezinto zokuwelda ezityebileyo. Kwelinye icala, umatshini onikwe amandla ngumthombo wamandla osezantsi osezantsi uya kuba ne-welding ephantsi yangoku kwaye usenokungasebenzi kwi-welding thicker materials.
Umthombo wamandla ukwachaphazela ubungakanani kunye nobunzima bomatshini. Umzekelo, umatshini onikwe amandla ngumthombo obalulekileyo wamandla uya kuba mkhulu, ngelixa umatshini onomthombo omncinci wamandla uya kuba compact ngakumbi. Uhlobo lomthombo wamandla nalo luya kumisela iindleko ze umatshini kunye nokugcinwa kwawo. I-spot welders ezisebenzisa amandla aphezulu zineendleko eziphezulu zokuqala kunye nokugcinwa kunoomatshini abanomthombo wamandla ophantsi.
Izinketho zolawulo
Xa kuthengwa i-spot welder, kukho iindlela ezimbalwa zokulawula ekufuneka uziqwalasele. Okokuqala, jonga ukuba ngaba abasebenzisi bafuna i-manual, i-semi-automatic, okanye i-automatic spot welder. Izixhobo zokuwelda zifuna ukuba umsebenzisi aqalise inkqubo yokuwelda, ngelixa i-semi-automatic kwaye iiwelder ezizenzekelayo zicwangciselwe ukuweld ngaphandle kwegalelo elithe ngqo lomsebenzisi.
Emva koko, qwalasela uhlobo lojongano lolawulo. Abaweldi bezandla bakholisa ukuba neqhosha lokuguqula okanye lokutyhala ngelixa i-semi-automatic kunye ne-automatic welders banokusebenzisa i-pedal yonyawo, umboniso wedijithali, okanye isilawuli esinocwangciso.
Abathengi kufuneka bajonge ukuba ngaba i-welder ibonelela ngoku kunye neempawu zolawulo lombane. Izixhobo zokuwelda ziyathengwa ngokusetwa kwangaphambili kwangoku kunye noseto lwevoltheji okanye useto oluhlengahlengiswayo ukuze umsebenzisi akwazi ukuguqula okwangoku kunye nombane njengoko kufuneka.
Ulawulo lweempawu zokhuseleko lwe-welder lubalulekile. Izixhobo zokuwelda ezifanelekileyo ziya kuba nezinto ezahlukeneyo zokhuseleko, ezinje ngokusikwa kwe-thermal, ukhuseleko lombane ophantsi, kunye nokhuseleko lomthwalo ogqithisileyo. Zonke ezi zinto zenza kube lula ukufumana i-welder yendawo eneenkonzo ezithembekileyo.
Izinto ezifanelekileyo
Xa uthengela i-spot welder, kubalulekile ukuqwalasela imathiriyeli efanelekileyo ngaphambi kokuthenga. Izixhobo zokuwelda ezahlukeneyo ziyilelwe ukusebenza ngemathiriyeli eyahlukeneyo, kwaye ukukhetha uhlobo olungalunganga lwe-welder kunokubangela ukuthotywa komgangatho wejoyinti elidityanisiweyo kunye nokusilela ngokupheleleyo. Umzekelo, i-spot welder yentsimbi ethambileyo ayifanelanga ukuwelda isilivere okanye i-magnesium.
