Musimboti:
Electric welding equipment ndiko kushandiswa kwesimba remagetsi, kuburikidza nekudziya uye kudzvanywa, kureva, tembiricha yepamusoro inogadzirwa neiyo yakanaka uye yakaipa maelectrode mupfupi pfupi, kunyungudutsa solder uye welded zvinhu pa electrode, nerubatsiro rwekubatanidzwa uye kupararira kwemaatomu esimbi, kuitira kuti maviri kana anopfuura mawelds anyatsobatanidzwa pamwe chete. Inonyanya kuumbwa ne electrode, yemagetsi welding muchina, yemagetsi welding tong, grounding clamp uye tambo yekubatanidza. Zvinoenderana nerudzi rwemagetsi anobuda, anogona kupatsanurwa kuita mhando mbiri, imwe ndeye AC welding muchina uye imwe ndeye DC welding muchina.
Welding muchinakubatana:
• Zvidzitiro zvinosungirirwa zvakabatanidzwa nemagetsi emagetsi ekubatanidza maburi pamushini wekugadzira kuburikidza netambo dzekubatanidza;
• Chigadziro chepasi chinosanganiswa nesimbi yepasi inobatanidza gomba pamushini we welding kuburikidza netambo yekubatanidza;
• Isa iyo weldment pane flux pad uye sunga simbi yepasi kune imwe mugumo we weldment;
• Wobva wasunga chikomborero mugumo we electrode kune welding shaya;
• Dziviriro yekudzivirira pasi kana zero yekubatanidza shell yemuchina we welding (chigadzirwa chepasi chinogona kushandisa pombi yemhangura kana pombi yesimbi isina musono, kudzika kwekuvigwa kwayo muvhu kunofanira kuva> 1m, uye kupikisa kwepasi kunofanira kuva <4Ω), kureva kuti, shandisa tambo kubatanidza imwe mugumo kune chigadziro chepasi uye imwe mugumo kusvika kumucheto wepasi wegokowelding muchina.
• Zvadaro batanidza welding machine nebhokisi rekugovera kuburikidza nemutsara wekubatanidza, uye iva nechokwadi chokuti kureba kwemutsara wekubatanidza ndeye 2 kusvika ku 3 mamita, uye bhokisi rekugovera rinofanira kunge rakagadzirirwa nemudziyo wekudzivirira wakawandisa uye kushandura banga, nezvimwewo, izvo zvinogona kudzora magetsi emagetsi emagetsi akasiyana.
• Asati apinza, mufambisi anofanira kupfeka zvipfeko zvewelding, shangu dzerubha dzakaiswa insulated, magirovhosi ekudzivirira, masiki ekudzivirira uye mamwe maturusi ekudzivirira, kuitira kuti ave nechokwadi chekuchengetedzwa kwemunhu anoshanda.
Kubatanidzwa kwesimba rekupinza uye kubuda kwewelding muchina:
Kazhinji pane 3 mhinduro dzetambo yekupinza magetsi: 1)waya mhenyu, waya isina kwayakarerekera, uye waya yepasi; 2)Waya mbiri mhenyu uye imwe pasi waya; 3)3 mhenyu waya, imwe pasi waya.
Mutsetse wekuburitsa wemagetsi welding muchina hausiyaniswe kunze kweiyo AC welding muchina, asi iyo DC welding muchina wakakamurwa kuita zvakanaka uye zvisina kunaka:
DC welding machine positive polarity connection: Iyo polarity yekubatanidza nzira yeDC welding muchina yakavakirwa pane workpiece sereferensi, kureva kuti, welding workpiece yakabatana kune yakanaka electrode kubuda kwemagetsi welding muchina, uye welding mubato (clamp) yakabatana kune iyo yakaipa electrode. Iyo yakanaka polarity yekubatanidza arc ine hunhu hwakaoma, iyo arc yakamanikana uye yakadzika, kupisa kwakadzika, kupinza kwakasimba, kupinza kwakadzika kunogona kuwanikwa neazvino diki, weld bead (weld) yakaumbwa idiki, uye welding nzira zvakare iri nyore kugona, uye zvakare ndiyo inonyanya kushandiswa kubatana.
DC welding machine negative polarity connection method (inonziwo reverse polarity connection): workpiece yakabatana kune negative electrode, uye welding handle yakabatana kune yakanaka electrode. Iyo yakaipa polarity arc yakapfava, inosiyana, isina kudzika kupinza, yakakura ikozvino, yakakura spatter, uye inokodzera nzvimbo dzine yakakosha welding process zvinodiwa, senge yekumashure chivharo chepamusoro pechivharo chekumashure, welding yakatarisana, uko welding bead inoda nzvimbo dzakafara uye dzakapfava, welding mahwendefa matete uye simbi yakakosha, nezvimwewo. Mukuwedzera, paunenge uchishandisa alkaline low-hydrogen electrodes, reverse connection yakanyanya kugadzikana kupfuura iyo yakanaka arc, uye chiyero che spatter idiki.
Kana zviri zvekushandisa zvakanaka polarity yekubatanidza kana isina kunaka polarity yekubatanidza nzira panguva yewelding, inofanirwa kusarudzwa zvinoenderana neiyo welding process,welding mamirirozvinodiwa uye electrode zvinhu.
Maitiro ekutonga polarity yekubuda kweDC welding muchina: Muchina wenguva dzose welding wakanyorwa ne + uye - pane inobuda terminal kana terminal board, + zvinoreva danda rakanaka uye - rinoratidza danda risina kunaka. Kana maelectrodes akanaka neakaipa asina kunyorwa, nzira dzinotevera dzinogona kushandiswa kuasiyanisa.
1) Epirical nzira. Paunenge uchishandisa low-hydrogen (kana alkaline) electrodes ye welding, kana kupisa kwearc kusina kugadzikana, spatter yakakura, uye inzwi rine chisimba, zvinoreva kuti nzira yekubatanidza mberi inoshandiswa; Zvikasadaro, zvinodzoserwa shure.
2) Marasha tsvimbo nzira. Kana iyo carbon rod nzira inoshandiswa kuona nzira yekubatanidza yekumberi kana reverse yekubatanidza nzira, inogona zvakare kutongwa nekucherechedza arc uye mamwe mamiriro:
a. Kana kupisa kwearc kwakagadzikana uye carbon rod inopisa zvishoma nezvishoma, inzira yakanaka yekubatanidza.
b. Kana iyo arc combustion isina kugadzikana uye kabhoni tsvimbo yakapiswa zvakanyanya, ndiyo nzira yekubatanidza reverse.
3) Multimeter nzira. Nzira nematanho ekushandisa multimeter kutonga nzira yekubatanidza yekumberi kana reverse yekubatanidza nzira ndeiyi:
a. Isa iyo multimeter munzvimbo yepamusoro yeDC voltage (pamusoro pe100V), kana shandisa iyo DC voltmeter.
b. Iyo multimeter peni uye DC welding muchina inobatwa zvakateerana, kana zvikaonekwa kuti chinongedzo chemultimeter chakatsauswa newachi, ipapo iyo terminal yemuchina wewelding wakabatana nepeni dzvuku ndiyo danda rakanaka, uye imwe magumo idanda rakashata. Kana iwe ukaedza nedhijitari multimeter, kana chiratidzo chisina kunaka chikaonekwa, zvinoreva kuti peni tsvuku yakabatana nedanda rakashata, uye hapana chiratidzo chinooneka, izvo zvinoreva kuti peni tsvuku yakabatana nedanda rakanaka.
Ehe, kune welding muchina unoshandiswa, iwe uchiri kutarisa rinoenderana bhuku.
Ndizvo zvese zvekutanga zvakagovaniswa nhasi muchinyorwa chino. Kana pane zvisina kufanira, ndapota nzwisisa uye gadzirisa
