Kuphela kukwazi impembelelo yendlela yokuwelda ekuwelding apho sinokuthi sisebenze ngcono size silungise khonaoomatshini bokwenza umbhobho we-longitudinal welded weldedukuze kufezekiswe ukusebenza kakuhle. Makhe sijonge impembelelo yeendlela zokuwelda kwiimashini zokuwelda ezithe nkqo ezisebenza rhoqo namhlanje.
Kukho iindlela ezimbiniukuwelda okuphindaphindwayo: ukuwelda okudibeneyo kunye nokuwelda okubangelwa kukufakelwa.
Ukuwelda ngokudibanisa kusebenzisa ii-electrode ezimbini zobhedu ezidibana namacala omabini ombhobho wentsimbi oza kuwelda. Umsinga obangelwayo ungena kakuhle. Iziphumo ezimbini zomsinga ophezulu ziphuculwa kakhulu ngenxa yoqhagamshelwano oluthe ngqo phakathi kwee-electrode zobhedu kunye nepleyiti yentsimbi. Ke ngoko, ukusebenza kakuhle kokuwelda kokuwelda ngokudibanisa kuphezulu kwaye kusetyenziswa amandla aphantsi, kusetyenziswa kakhulu ekuveliseni iipayipi ezikhawulezayo nezichanekileyo, kwaye ukuwelda ngokudibanisa kudla ngokufuneka xa kusenziwa iipayipi zentsimbi ezixineneyo. Nangona kunjalo, kukho iingxaki ezimbini ekuwelda ngokudibanisa: enye kukuba i-electrode yobhedu idibana nepleyiti yentsimbi, kwaye iyaguga ngokukhawuleza; enye kukuba ngenxa yempembelelo yokuthamba komphezulu wepleyiti yentsimbi kunye nokuthe tye komphetho, uzinzo lwangoku lokuwelda ngokudibanisa alulunganga, kwaye ii-burrs zangaphakathi nezangaphandle ze-weld ziphezulu. , Ngokuqhelekileyo ayisetyenziswa xa kuwelda iipayipi ezichanekileyo nezinodonga oluncinci.
Ukuwelda ngokungenisa kukusonga ijika elinye okanye ngaphezulu leekhoyili zokungenisa ngaphandle kombhobho wentsimbi ukuze ziweldiwe. Isiphumo sokujika okuninzi singcono kunokujika kube kanye, kodwa kunzima ngakumbi ukuvelisa nokufaka iikhoyili zokungenisa ezininzi. Ukusebenza kakuhle kuphezulu xa umgama phakathi kwekhoyili yokungenisa kunye nomphezulu wombhobho wentsimbi umncinci, kodwa kulula ukubangela ukukhupha phakathi kwekhoyili yokungenisa kunye nombhobho. Ngokubanzi, kuyacetyiswa ukugcina umsantsa we-5-8 mm phakathi kwekhoyili yokungenisa kunye nomphezulu wombhobho wentsimbi. Xa usebenzisa i-induction welding, ekubeni i-induction coil ingadibani nepleyiti yentsimbi, akukho kuguga, kwaye umsinga wokungenisa uzinzile, oqinisekisa uzinzo lokuwelda. Umgangatho womphezulu wombhobho wentsimbi ngexesha lokuwelda ulungile, kwaye umthungo we-weld uthambile. Kwimibhobho echanekileyo, kusetyenziswa i-induction welding ngokusisiseko.
