1. Ukhetho oluchanekileyo lweeparamitha ze-welding
(1) I-Welding current kunye ne-arc voltage Kwi-CO2 yegesi ekhuselekileyo ye-welding, kwi-diameter nganye yocingo lwe-welding, kukho umthetho othile phakathi kwesantya sokutshiza kunye ne-welding current. Kummandla omfutshane wenguqu yangoku encinci, isantya se-welding spatter sincinci. Emva kokungena kwindawo yokutshintsha i-particle ye-fine of current high, i-welding spatter rate nayo incinci, kwaye i-welding spatter rate iyona inkulu kwindawo ephakathi. Ukuthatha ucingo ngobubanzi be-1.2 mm njengomzekelo, xa i-welding current ingaphantsi kwe-150A okanye ingaphezulu kwe-300A, i-spatter ye-welding incinci, kwaye phakathi kwezi zibini, i-welding spatter inkulu. Xa ukhetha i-welding current, indawo yangoku ye-welding kunye nesantya esiphezulu se-welding spatter kufuneka igwenywe kangangoko kunokwenzeka, kwaye i-arc voltage efanelekileyo kufuneka ihambelane emva kokuba i-welding current inqunywe.
(2) Ubude bolwandiso lwentambo yokuwelda: Ubude bolwandiso lwentambo yokuwelda (oko kukuthi ukunwenwa okomileyo) nako kunefuthe kwi-spatter ye-welding. Okukhona ubude bokwandiswa kocingo lwe-welding, kokukhona i-welding spatter inkulu. Ngokomzekelo, ngocingo olunobubanzi be-1.2mm, xa i-welding yangoku i-280A, xa ubude bokwandiswa kocingo bunyuka ukusuka kwi-20mm ukuya kwi-30mm, inani le-welding spatter landa malunga ne-5%. Ngoko ke, kuyafuneka ukuba ubude bokwandiswa kocingo lwe-welding kufuneka bufutshane
2. Ukuphucula umthombo wamandla we-welding
Isizathu sokutshiza kwi-CO2 yegesi ekhuselekileyo ye-welding ikakhulu kwinqanaba lokugqibela lenguqu ye-short-circuit, ngenxa yokunyuka okubukhali kwe-short-circuit current, i-metal bridge metal ishushu ngokukhawuleza, okubangela ukuqokelela kobushushu, kwaye ekugqibeleni, ibhuloho yolwelo iqhuma ukuvelisa i-splashes. Ukuqwalasela ukuphuculwa komthombo wamandla we-welding, iindlela ezifana nodibaniso lwe-reactors kunye ne-resistors, ukutshintshwa kwangoku, kunye nolawulo lwangoku lwe-waveform kwi-welding circuit isetyenziselwa ukunciphisa ukuqhuma kwangoku kwebhulorho yolwelo kwaye ngaloo ndlela kuncitshiswe i-welding spatter. Okwangoku, i-thyristor-type-controlled wave-controlled CO2 gas shielded welding machines kunye ne-inverter-type transistor-type-controlled wave-controlled CO2 gas shielded welding machines zisetyenzisiwe, kwaye ziphumelele impumelelo ekunciphiseni ukutshiza kwe-CO2 yegesi ekhuselekileyo.
3. Yongeza i-argon (Ar) kwigesi ye-CO2:
Emva kokongeza inani elithile legesi ye-argon kwigesi ye-CO2, iimpawu ezibonakalayo kunye neekhemikhali zegesi ye-CO2 zatshintshwa. Ngokunyuka kwe-argon gas ratio, i-spatter ye-welding yehla ngokuthe ngcembe, kwaye eyona nguqu ibalulekileyo kwilahleko ye-spatter yayixa i-particle idayamitha yayinkulu kune-0. 8mm yokutshiza, kodwa inefuthe elincinane kwi-spatter kunye ne-particle ububanzi ngaphantsi kwe-0.8mm.
Ukongeza, ukusetyenziswa kwe-welding ekhuselweyo yegesi edibeneyo apho i-argon yongezwa kwi-CO2 yegesi inokuphucula ukubunjwa kwe-weld. Isiphumo sokongeza i-argon kwigesi ye-CO2 ekungeneni kwe-weld, ububanzi bokudibanisa kunye nokuphakama okushiyekileyo, kunye ne-argon kwigesi ye-CO2. Njengoko umxholo wegesi ukhula, ubunzulu bokungena buyancipha, ububanzi be-fusion buyanda, kwaye ukuphakama kwe-weld kuncipha.
4. Sebenzisa ucingo olusezantsi lwe-welding
Ngocingo oluqinileyo, kwisiseko sokuqinisekisa iimpawu zomatshini wokudibanisa, ukunciphisa umxholo wekhabhoni kangangoko kunokwenzeka, kwaye ngokufanelekileyo ukwandisa izinto ezixutywayo ezifana ne-titanium kunye ne-aluminium kunokunciphisa ngokufanelekileyo i-welding spatter.
Ukongeza, ukusetyenziswa kwe-flux-cored wire CO2 gas shielded welding inokunciphisa kakhulu i-welding spatter, kunye ne-welding spatter eveliswa yi-flux-cored welding wire imalunga ne-1/3 yocingo oluqinileyo lwe-welding.
5. Ulawulo lwe-engile yetotshi ye-welding:
Xa itotshi ye-welding i-perpendicular kwi-weldment, ubuncinane be-spatter ye-welding iveliswa, kwaye i-angle enkulu yokuthambekela, i-spatter eninzi. Xa i-welding, i-angle inclination ye-welding torch akufanele idlule i-20º.
