Pamene malawi akuuluka, weld spatter pa workpiece nthawi zambiri sakhala kumbuyo. Pamene spatter ikuwonekera, iyenera kuchotsedwa - zomwe zimawononga nthawi ndi ndalama. Kupewa ndikwabwino kuposa kuyeretsa, ndipo tiyenera kupewa kuwotcherera spatter momwe tingathere - kapena kuchepetsa kuchepera. Koma bwanji? Wowotchera aliyense ali ndi mphamvu zothandizira kuthana ndi spatter, kaya pogwiritsa ntchito zida zabwino kwambiri zowotcherera, kukonza zida moyenera, kugwira mfuti yowotcherera moyenera, kapena kusintha pang'ono pantchito. Ndi malangizo 8 awa, inunso mutha kulengeza nkhondo pa weld spatter!
Kupewa Weld Spatter
— N’chifukwa chiyani kuli kofunika kwambiri?
Weld spatter amatanthauza madontho ang'onoang'ono achitsulo omwe amatulutsidwa kuchokera kumalo otsekemera ndi mphamvu ya arc - nthawi zambiri amatera pa workpiece, weld seam, kapena kuwotcherera mfuti. Kuphatikiza pakupanga nthawi yoyeretsa komanso yowononga ndalama, weld spatter imathanso kuyambitsa mavuto awa:
- Kuchepetsa khalidwe la weld
- Malo ogwirira ntchito odetsedwa komanso osatetezeka
- Kuchepetsa nthawi yopanga
Chifukwa chake, spatter ya weld iyenera kupewedwa momwe mungathere. Ndi malangizo athu ofulumira, mudzakhala okonzeka. Tiyeni tiyambe ndi zida zabwino kwambiri zowotcherera!
1.
Onetsetsani kuti madzi akuyenda bwino
Kukhazikika kwapano ndikofunikira kuti mupewe kuwotcherera spatter. Mfuti yowotcherera ndi chingwe chobwerera ziyenera kulumikizidwa bwino ndi gwero lamagetsi. Zomwezo zimagwiranso ntchito poyika maziko a workpiece: malo omangirira ndi choyikapo pansi ayenera kukhala opanda kanthu komanso oyendetsa bwino kwambiri kuti azitha kuyenda.
2.
Onetsetsani kuti pali chakudya cha waya nthawi zonse
Kuti kuwotcherera ndi spatter pang'ono momwe ndingathere, arc iyenera kukhala yokhazikika. Kuti mupeze arc yokhazikika, mukufunikira chakudya chokhazikika chawaya. Kuti izi zitheke, zinthu zitatu ndizofunikira:
- Onetsetsani kuti mfuti yowotcherera idayikidwa bwino (chingwe cha waya (m'mimba mwake ndi kutalika), nsonga yolumikizirana, ndi zina zambiri).
- Onetsetsani kuti pali zopindika zochepa mu thunthu momwe mungathere.
- Sinthani mphamvu yolumikizana ndi mawaya odzigudubuza kuti agwirizane ndi waya womwe ukugwiritsidwa ntchito.
"Kukanika pang'ono kumapangitsa kuti waya adutse, zomwe zingayambitse vuto la kudya mawaya ndikuyamba kukhala ndi vuto la spatter," akufotokoza motero Josef Sider wowotcherera.
Kupindika mochulukira kwa mzere wa thunthu kumapangitsa kuti mawaya asamadye bwino, zomwe zimapangitsa kuti pakhale vuto la spatter
Choyenera kuchita: Chepetsani kupindika pamzere wopatsirana

Sankhani mpweya wabwino wotchingira ndi liwiro loyenda bwino
Kusakwanira kwa mpweya wotchinga kungayambitse kusakhazikika kwa arc, komwe kumayambitsa kufalikira kwa weld. Pali zinthu ziwiri zofunika kwambiri pano: kuchuluka kwa gasi (ulamuliro wa chala chachikulu: waya m'mimba mwake x 10 = kuchuluka kwa gasi mu l/min) ndi chomata (mapeto a waya wotuluka pansonga yolumikizirana), yomwe iyenera kukhala yayifupi. zokwanira kuonetsetsa ogwira gasi chitetezo. Kuwotcherera kwapang'ono pang'ono kumadaliranso kusankha mpweya wabwino, chifukwa kuwotcherera mu mpweya wabwino wa CO2 kumatulutsa spatter yambiri mumtundu wapamwamba wamagetsi. Malangizo athu: gwiritsani ntchito gasi wosakanizidwa m'malo mwa 100% CO2 kuti muchepetse mwayi wa weld spatter!

Sankhani zoyenera zogwiritsidwa ntchito
Pankhani ya consumables ndi weld spatter, pali zinthu zingapo zomwe muyenera kuziganizira. Choyamba, zogwiritsidwa ntchito monga ma spools a waya, machubu odyetsa mawaya kapena maupangiri olumikizana ayenera kukhala oyenera pazinthu ndi mainchesi a waya wowotcherera. Chachiwiri, kuchuluka kwa kuvala kumakhudza mapangidwe a spatter. Ziwalo zong'ambika kwambiri zimatha kuyambitsa njira yowotcherera yosakhazikika, zomwe zimapangitsa kuti pakhale ma weld spatter.
5.
Ikani magawo oyenera kuwotcherera
Kusankha magawo oyenera kuwotcherera ndikofunikira kuti mupewe kuwotcherera momwe mungathere, makamaka pokhazikitsa mtundu wamagetsi a arc yapakatikati. Kutengera momwe zinthu ziliri, mphamvuyo iyenera kuonjezedwa kapena kuchepetsedwa kuti isinthe kupita ku arc yotengera madontho kapena jet arc.
6.
Zida zoyera
Zinthu zoyera bwino ndi chinthu chinanso chofunika kwambiri. Asanayambe kuwotcherera, dothi, dzimbiri, mafuta, sikelo kapena zinki zigawo ziyenera kuchotsedwa pamalo owotcherera.
7.
Kuchita bwino kwa mfuti zowotcherera
M'pofunikanso kulabadira malo olondola ndi chitsogozo cha kuwotcherera mfuti. Mfuti yowotcherera iyenera kusungidwa pa ngodya ya 15 ° ndikusuntha pamodzi ndi weld pa liwiro lokhazikika. "Njira yowotcherera yotchulidwa kuti 'kankhira' ndiyosavomerezeka, chifukwa izi zimapangitsa kuti pakhale ma ejection ambiri," akuwonjezera Josef Sider. Mtunda wopita ku workpiece uyeneranso kukhala wosasinthasintha. Ngati mtunda uli waukulu kwambiri, chitetezo ndi kulowa kwa mpweya wotchinga zimakhudzidwa, zomwe zimapangitsa kuti pakhale spatter yambiri pamene kuwotcherera.
8.
Kupewa zojambula zozungulira
Langizo lothandiza lomwe nthawi zambiri limamanyalanyazidwa ndikupewa zojambula zozungulira. "Mukawotchera m'galaja yokhala ndi mpweya wamphamvu, mutha kuthana ndi vuto ndi gasi woteteza," akufotokoza Sider. Ndipo, ndithudi, pali weld spatter. Mukawotchera panja, sizotheka nthawi zonse kuteteza malo owotcherera, koma mwamwayi Sider ali ndi nsonga yapamwamba: Wonjezerani mpweya wotchinga ndi pafupifupi 2-3 l/min kuti musunthire mpweya wozungulira kutali ndi malo owotcherera.
Mukadali wopaka weld wambiri?
Mutha kusintha ndondomeko yanu yowotcherera
Mukaganizira malangizo onsewa, mudzakhala ndi arc yokhazikika yomwe imatha kuthana ndi kutulutsa kwa spatter panthawi yowotcherera. Komabe, ngati mukufuna kukhazikika komanso kuti muchepetse kuchuluka kwa spatter yomwe imapangidwa, mungaganizire kusintha njira yowotcherera. The bwino LSC (Low Spatter Control) droplet transfer arc - yomwe imadziwikanso kuti "low spatter" kuwotcherera, yomwe imapezeka pa Fronius TPS / i platform - ndi yabwino pazosowa zotere, chifukwa imapereka ntchito yapamwamba kwambiri ya arc, kupereka. inu ma weld apamwamba kwambiri okhala ndi sipatter yochepa.
Weld ndi sipatter yochepa - pogwiritsa ntchito njira yowotcherera ya LSC
Pali zinthu zambiri zomwe mungachite kuti mupewe kapena kuchepetsa kutentha kwa weld, ndipo muyenera. Kupatula apo, kuwotcherera kwa spatter kochepa kumatha kukupulumutsirani nthawi ndi ndalama kwinaku mukuwongolera zowotcherera ndikuwonetsetsa kuti malo ogwirira ntchito ali otetezeka.
