1. Daidaitaccen zaɓi na sigogin walda
(1) Welding current da arc volt A cikin CO2 gas kariya waldi, ga kowane diamita na walda waya, akwai wata doka tsakanin spatter kudi da waldi halin yanzu. A cikin ɗan gajeren zangon miƙa mulki na ƙaramin halin yanzu, ƙimar spatter walda kaɗan ne. Bayan shigar da kyau barbashi mika mulki yankin na high halin yanzu, waldi spatter kudi ne kuma kananan, da waldi spatter kudi ne mafi girma a tsakiyar yankin. Ɗaukar waya mai diamita na 1.2 mm a matsayin misali, lokacin waldawar halin yanzu bai wuce 150A ko sama da 300A ba, spatter ɗin walda yana da ƙananan, kuma tsakanin su biyun, spatter na walda yana da girma. A lokacin da zabar waldi halin yanzu, waldi halin yanzu yankin da high waldi spatter kudi ya kamata a kauce masa kamar yadda zai yiwu, da kuma dace baka ƙarfin lantarki ya kamata a daidaita bayan waldi halin yanzu da aka ƙayyade.
(2) Tsawon tsawo na walda: Tsawon tsawo na walda (watau bushewar elongation) shima yana da tasiri akan spatter walda. Tsawon tsayin tsayin wayan walda, mafi girman spatter ɗin walda shine. Misali, ga waya mai diamita na 1.2mm, lokacin waldi na halin yanzu shine 280A, lokacin da tsayin waya ya karu daga 20mm zuwa 30mm, adadin spatter walda yana ƙaruwa da kusan 5%. Sabili da haka, ana buƙatar cewa ya kamata a rage tsawon tsayin waya mai waldawa
2. Inganta tushen wutar lantarki
Dalilin fantsama a cikin walda mai kariya na CO2 shine galibi a mataki na ƙarshe na ɗan gajeren lokaci, saboda ƙayyadaddun ƙayyadaddun ƙayyadaddun lokaci, ƙarfen gada na ruwa yana da sauri mai zafi, yana haifar da tara zafi, kuma a ƙarshe, gadar ruwa ta fashe don haifar da splashes. Idan aka yi la'akari da inganta tushen wutar lantarki, hanyoyin kamar jerin haɗin reactors da resistors, sauyawa na yanzu, da kuma sarrafa waveform na yau da kullun a cikin da'irar walda galibi ana amfani da su don rage fashewar halin yanzu na gada ta ruwa kuma don haka rage walda spatter. A halin yanzu, an yi amfani da injunan walda mai nau'in thyristor-nau'in CO2 gas mai kariya da inverter-nau'in transistor-nau'in raƙuman ruwa mai sarrafa iskar gas ɗin CO2 gas ɗin waldawa, kuma sun sami nasara wajen rage ɓarna na CO2 gas ɗin walda.
3. Ƙara argon (Ar) zuwa iskar CO2:
Bayan ƙara wasu adadin iskar argon zuwa iskar CO2, an canza yanayin jiki da sinadarai na CO2 gas. Tare da karuwa na argon gas rabo, walda spatter sannu a hankali rage, kuma mafi muhimmanci canji ga spatter asarar shi ne lokacin da barbashi diamita ya fi 0. 8mm spatter, amma yana da kadan tasiri a kan spatter tare da barbashi diamita kasa da 0.8mm.
Bugu da kari, yin amfani da gauraye garkuwar walda wanda ake kara argon zuwa iskar CO2 na iya inganta samar da walda. Tasirin ƙara argon zuwa CO2 gas akan shigar weld, nisa fusion da tsayin saura, tare da argon a cikin iskar CO2. Yayin da abun ciki na iskar gas ke ƙaruwa, zurfin shigar ciki yana raguwa, faɗin haɗakarwa yana ƙaruwa, kuma tsayin walda yana raguwa.
4. Yi amfani da ƙananan spatter waldi waya
Don m waya, a kan jigo na tabbatar da inji Properties na hadin gwiwa, rage carbon abun ciki kamar yadda zai yiwu, da kuma yadda ya kamata ƙara alloying abubuwa kamar titanium da aluminum iya yadda ya kamata rage walda spatter.
Bugu da kari, yin amfani da walda mai kariyar da ake yi na CO2 gas na iya rage yawan walda, kuma magudanar walda da aka samar ta hanyar waldawar waya ya kai kashi 1/3 na na waya mai kauri.
5. Sarrafa kusurwar walda:
Lokacin da fitilar walda ta kasance perpendicular zuwa waldi, ana samar da mafi ƙarancin adadin walda, kuma mafi girman kusurwar karkata, ƙarin spatter. Lokacin waldawa, kusurwar karkatar da fitilar walda kada ta wuce 20º.
Lokacin aikawa: Juni-22-2022
