Ⅱ.Argon arc welding e lokisa
1. Beha switjha sebakeng sa welding ea argon.
2. Bula valve ea argon cylinder mme u fetole meter ea phallo ho phallo e hlokahalang.
3. Bulela sesebelisoa sa matla holim'a phanele, leseli la pontšo ea matla le khantšitsoe, 'me fan e ka hare ho mochine e sebetsa.
4. Tobetsa konopo ea ho sebetsana le toche ea welding, valve ea solenoid e tla sebetsa, 'me tlhahiso ea khase ea argon e tla qala.
5. Khetha hona joale welding ho ea ka botenya ba workpiece.
6. Beha electrode ea tungsten ea lebone la tjheseletsa sebakeng se hole sa 2-4mm ho tloha mosebetsing, tobetsa konopo ea toche ea welding ho hotetsa arc, 'me molumo o phahameng oa maqhubu a ho ntša arc-igniting mochine o nyamela hang-hang.
7. Khetho ea ho phunya: tlase ha e na sekhahla, bohareng ke sekhahla sa maqhubu a mahareng, 'me ka holimo ke sekhahla se tlaase.
8. 2T / 4T khetho ea ho khetha: 2T ke ea ho tjheseletsa ha pulse argon arc, 'me 4T ke ea welding e feletseng.Fetola nako ea hona joale ea ho qala, nako e ntseng e phahama, ea hona joale ea tjheseletsa, boleng ba hona joale, nako ea hona joale ea ho theoha, nako ea crater current le ea post-gas ho latela mokhoa o hlokahalang oa ho cheselletsa.
Sebaka se pakeng tsa electrode ea tungsten ea toche ea welding le workpiece ke 2-4mm.Tobetsa sesebelisoa sa toche, arc e chesoa ka nako ena, lokolla sesebelisoa sa letsoho, hona joale se nyoloha butle-butle ho ea holimo hona joale, 'me welding e tloaelehileng e etsoa.
Ka mor'a hore sesebelisoa se kenngoe, tobetsa konopo ea letsoho hape, hona joale e tla theoha butle-butle ho arc e koalang hona joale, 'me ka mor'a hore likoting tsa matheba a ho tjheseletsa li tlatsitsoe, lokolla mochine oa letsoho,' me mochine oa ho tjheseletsa o tla emisa ho sebetsa.
9. Phetoho ea nako ea ho fokotsa nako: nako ea ho fokotsa nako e ka ba ho tloha ho 0 ho isa ho metsotsoana e 10.
10. Nako ea ho fana ka nako: Ka mor'a ho fana ka nako e bua ka nako ea ho emisa ha arc welding ho ea qetellong ea phepelo ea khase, 'me nako ena e ka fetoloa ho tloha metsotsoana e 1 ho isa ho e 10.
Ⅲ.Ho lokisa welding ka letsoho
1. Beha switjha ho "ho tjheseletsa ka letsoho"
2. Khetha hona joale welding ho ea ka botenya ba workpiece.
3. Tlrust current: Tlas'a maemo a tjheseletsa, lokisa kotola ho latela tlhoko.The thrust knob e sebelisetsoa ho lokisa ts'ebetso ea ho tjheseletsa, haholo-holo ka mefuta e mengata ea hona joale e nyenyane ha e sebelisoa hammoho le knob ea phetoho ea hona joale, e ka khonang habonolo ho fetola sekhahla sa arcing ntle le Ho laoloa ke knob ea phetoho ea tjheseletsa hona joale.
Ka tsela ena, ts'ebetsong ea welding ea hona joale e nyane, ho ka fumanoa mokelikeli o moholo, e le ho finyella phello ea ho etsisa mochine o potolohang oa DC.
Ⅳ.Koala
1. Tima sesebelisoa se seholo sa matla.
2. Hakolla konopo ea taolo ea lebokose la metha.
Ⅴ.Litaba tsa ts'ebetso
1. Mosebetsi oa ho hlokomela le ho lokisa o tlameha ho etsoa tlas'a boemo ba ho khaola ka ho feletseng phepelo ea motlakase.
2. Hobane argon arc welding e na le motlakase o moholo oa ho sebetsa o fetang ho eona, mosebedisi o lokela ho tiisa hore moea oa moea ha o koaheloe kapa o thibetsoe, 'me sebaka se pakeng tsa mochine oa welding le lintho tse potolohileng ha se ka tlase ho limithara tse 0,3.Ho boloka moea o motle ka tsela ena ho bohlokoa haholo hore mochini oa welding o sebetse hantle le ho netefatsa bophelo bo bolelele ba ts'ebeletso.
3. Overload e thibetsoe: mosebedisi o lokela ho boloka palo e phahameng e lumelletsoeng ea mojaro hona joale ka nako leha e le efe, 'me u boloke motlakase oa welding o sa fete boholo ba mojaro o amohelehang oa hona joale.
4. Thibelo ea motlakase o feteletseng: Tlas'a maemo a tloaelehileng, potoloho ea matšeliso ea motlakase o ikemetseng ho welder e tla etsa bonnete ba hore motlakase o lula o le ka har'a sebaka se amohelehang.Haeba motlakase o feta sebaka se lumelletsoeng, welder e tla senyeha.
5. Kamehla hlahloba ho hokahanya ha potoloho ea ka hare ea mochine oa welding ho tiisa hore potoloho e kopantsoe ka nepo 'me motsoako o tiile.Haeba e fumanoa e le mafome ebile e hlephile.Sebelisa sandpaper ho tlosa lera la mafome kapa filimi ea oxide, kopanya hape le ho tiisa.
6. Ha mochine o sebelisoa, u se ke ua lumella matsoho, moriri le lisebelisoa hore li atamele haufi le likarolo tse phelang ka har'a mochine.(joaloka li-fan) ho qoba kotsi kapa tšenyo ea mochini.
7. Hlakola lerōle khafetsa ka moea o omileng le o hloekileng.Tikolohong ea mosi o boima le tšilafalo e tebileng ea moea, lerōle le lokela ho tlosoa letsatsi le leng le le leng.
8. Qoba metsi kapa mouoane oa metsi o kenang ka hare ho mochine oa welding.Haeba sena se etsahala, omisa ka hare ho welder mme o lekanye ho kenngoa ha welder ka megohmmeter.Ka mor'a ho netefatsa hore ha ho na ntho e sa tloaelehang, e ka sebelisoa ka mokhoa o tloaelehileng.
9. Haeba welder e sa sebelisoe nako e telele, khutlisetsa welder ka lebokoseng la ho paka la pele 'me ue boloke sebakeng se omileng.
