Resistance spot welding ke mokhoa o sebelisoang haholo oa ho kopanya tlhahiso, 'me nako ea pele ho welding ke ntlha ea bohlokoa e ka amang boleng ba weld haholo. Sehloohong sena, re tla tšohla mokhoa oa ho fetola nako ea pele ho tjheseletsa mochini oa ho tjheseletsa letheba la ho hanyetsa ho fihlela liphetho tse ntle.
Ho utloisisa Nako ea Pele ho Welding:
Pele u kenella tšebetsong ea tokiso, ho bohlokoa ho utloisisa hore na nako ea pele ho welding ke eng le hore na ke hobane'ng ha e le bohlokoa. Nako ea pele ho tjheseletsa, e tsejoang hape e le nako ea ho petetsa kapa nako ea ho ts'oara, ke nako eo ka eona li-electrode tsa welding li kopanang le li-workpieces pele ho sebelisoa hona joale oa welding. Nako ena e lumella li-electrode ho beha khatello holim'a li-workpieces, ho theha sebopeho se kopantsoeng se thata le ho tlosa litšila leha e le life tsa holim'a metsi, ho etsa bonnete ba hore ho na le weld e matla le e ka tšeptjoang.
Lintlha tse Susumetsang Nako ea Pele ho Welding:
Lintlha tse 'maloa li ka ama nako e nepahetseng ea ho tjheseletsa pele bakeng sa ts'ebeliso ea welding e fanoeng:
- Mofuta oa thepa:Lisebelisoa tse fapaneng li na le li-conductivity tse fapaneng tsa mocheso le ho hanyetsa motlakase. Ka lebaka leo, li ka hloka linako tse fapaneng tsa ho tjheseletsa pele ho ho fihlela boleng bo lakatsehang ba weld.
- Botenya ba Lintho:Lisebelisoa tse teteaneng hangata li hloka nako e telele pele ho tjheseletsa ho netefatsa hore ho futhumala hantle le ho phalla ha thepa.
- Matla a Electrode:Matla a sebelisoang ke li-electrode tsa welding a phetha karolo ea bohlokoa ho khetholla nako e hlokahalang pele ho tjheseletsa. Matla a phahameng a ka hloka nako e telele pele ho tjheseletsa.
- Geometry ea Electrode:Sebopeho le boholo ba li-electrode tsa welding li ka ama ho ajoa ha khatello le hona joale, tse ka susumetsang nako e hlokahalang pele ho tjheseletsa.
Ho Lokisa Nako ea Pele ho Welding:
Ho fetola nako ea pele ho tjheseletsa bakeng sa mochini oa tjheseletsa sebakeng sa ho hanyetsa, latela mehato ena:
- Utloisisa Lintho Tsa Hao:Fumana mofuta le botenya ba thepa eo u e tjheseletsang. Sheba litataiso tsa li-welding kapa u buisane le litsebi tsa thepa ha ho hlokahala.
- Nahana ka Matla a Electrode:Etsa bonnete ba hore matla a electrode a behiloe ka nepo. Haeba matla a le tlase haholo, ho ka 'na ha hlokahala hore u eketse nako ea pele ho tjheseletsa ho lefella khatello e sa lekaneng.
- Teko:Hangata hoa hlokahala ho etsa letoto la li-welds tsa liteko ka linako tse fapaneng tsa pele ho tjheseletsa ho fumana nako e nepahetseng bakeng sa ts'ebeliso ea hau e ikhethileng.
- Hlahloba Boleng ba Weld:Ka mor'a tlhahlobo e 'ngoe le e' ngoe ea weld, hlahloba ka hloko boleng ba weld. Sheba matšoao a ho se kopane ho lekaneng, spatter e feteletseng, kapa liphoso tse ling. Nako e loketseng pele ho tjheseletsa e lokela ho fella ka weld e tsitsitseng, ya boleng bo phahameng.
- Rekota Liphetho:Boloka tlaleho ea linako tse sebelisoang pele ho tjheseletsa tekong ka nngwe, mmoho le boleng bo tsamaelanang le weld. Lintlha tsena li tla u thusa ho tseba nako e ntle ka ho fetisisa ea ho cheselletsa li-welds tse tlang.
- Choriso:Tsoela pele ho lokisa le ho lokisa nako ea pele ho tjheseletsa ho fihlela o dula o fihlella boleng bo lakatsehang ba weld.
Ho fetola nako ea pele ho tjheseletsa bakeng sa mochini oa tjheseletsa oa sebaka sa ho hanyetsa ke mohato oa bohlokoa oa ho fihlela li-welds tsa boleng bo holimo. Ka ho nahana ka thepa ea thepa, matla a li-electrode, le ho etsa liteko tse hlophisitsoeng, o ka fumana nako e nepahetseng ea pele ho tjheseletsa bakeng sa ts'ebeliso ea hau e khethehileng ea welding. Tlhokomelo ena ea lintlha e tla fella ka li-welds tse matla, tse ts'epahalang le ho ntlafatsa katleho ea tlhahiso ka kakaretso.
