Tack welding ke mokhoa oa mantlha lits'ebetsong tse ngata tsa tlhahiso le ho kopanya. Ho feta moo, mokhoa ona o sebelisoa haholo liindastering tse fapaneng ka lebaka la ho feto-fetoha ha oona, bokhoni ba ho tsitsisa, le ho boloka litšenyehelo.
Ka hona, sengoloa sena se tla hlahloba ts'ebetso ea welding ea tack, e koahelang tlhaloso ea eona, mefuta e fapaneng, hammoho le melemo le likotsi, ho thusa babali ho utloisisa ka botlalo mokhoa ona oa welding.
Tack Welding ke eng?
Tack weld ke tjheseletso ya nakwana e sebediswang ho tshwara dikotoana tse pedi kapa ho feta tsa tshepe pele o etsa weld ya ho qetela. Mokhoa ona o atisa ho kenyelletsa tšebeliso ea mocheso o tlaase le arc e khutšoanyane ea welding ho kopanya likarolo tsa tšepe hammoho.
Ho feta moo, morero oa ts'ebetso ena ke ho hokahanya likotoana tsa tšepe ka nepo pele ho tjheseletsa. 'Me e boetse e thibela likarolo ho tloha kapa ho sisinyeha nakong ea ts'ebetso ea welding. Ka mantsoe a mang, e ka fana ka botsitso bo lekaneng ho lumella welder ho phetha weld ea ho qetela ka katleho. Kahoo, welding ea nakoana ke mohato oa pele oa bohlokoa lits'ebetsong tse ngata tsa welding.
Tack Welding e sebetsa Joang?
Hoa tsebahala hore ts'ebetso ena ea welding hangata e sebelisa arc ho lokisa likotoana tse peli. Ka hona, tack welding ke ts'ebetso e batlang e le bonolo ha e bapisoa le e meng, 'me ka tlase ke mehato e meng e tloaelehileng.
- Tokisetso : Ho bohlokoa ho utloisisa lits'oants'o le litlhoko tsa tekheniki pele o qala tjheseletsa. Ka mor'a moo, e boetse e hloka ho netefatsa hore sebaka sa welding se lula se hloekile ebile ha se na li-oxide tse ling.
- Mekhahlelo Tokiso: Li-welder tse nkehang tse kang MIG welder le TIG welder, hangata li sebelisoa ts'ebetsong ena. Ka hona, welder e tla fetola motlakase oa welding le voltage hore e lekane le botenya le mefuta ea lisebelisoa tsa welding.
- Ho qoela : Mocheso o futhumetseng o entsoeng ke li-arc welds o tla etsa hore litšepe tsa welding li qhibilihe ka potlako. Joale litšepe li pholile ka potlako hang ha tjheseletso e felile. Ka kakaretso, bolelele ba li-tack tse nyane bo tloha ho ½ inches ho isa ho ¾ inches, 'me ha bo fete 1 inch.

Mefuta ea li-Welds tsa Tack
Mofuta o mong le o mong oa tack weld o sebeletsa lits'ebetso le merero ea ona e ikhethileng, 'me karolo ena e tla hlahisa mefuta e meng e tloaelehileng.
Standard Tack Weld
Mofuta ona oa weld o ka mamella lisebelisoa tse boima 'me oa tšoara likotoana ka thata bakeng sa ts'ebetso ea ho qetela ea welding.
Bridge Tack Weld
Ka tloaelo, li-welders li atisa ho sebelisa monyetla oa mokhoa ona ha ho e-na le lekhalo le lenyenyane pakeng tsa lisebelisoa tse peli tsa tšepe ka mor'a kopano. Ka mantsoe a mang, mokhoa ona o reretsoe ho tlatsa likheo tse bakoang ke ho seha kapa ho khopama ho sa lokelang.
Mona ke tse ling tsa litsebo mofuteng ona oa ho cheselletsa: ho sebelisa litšepe tse nyane karolong e 'ngoe le e 'ngoe ka ho latellana, ho ba fa nako e lekaneng ea hore ba phomole.
Hot Tack Weld
Hot tacking e tšoana le borokho tacking, kaha mekhoa ka bobeli e reretsoe ho tlatsa likheo. Leha ho le joalo, phapang ea bohlokoa ke hore ho chesa ho hloka hore motho ea chesehelang a sebelise sledgehammer ho phunya likotoana sebakeng se nepahetseng.
Thermit Tack Weld
Thermit welding ke ts'ebetso e sebelisang karabelo ea lik'hemik'hale e makatsang ho hlahisa mocheso o phahameng, o ka fihlang ho likhato tse 4000 tsa Fahrenheit. Ho phaella moo, e boetse e kenyelletsa motsoako oa lisebelisoa, tse kang phofo ea aluminium le phofo ea iron oxide.
Ultrasonic Tack Weld
Ultrasonic welding e kenyelletsa ts'ebeliso ea li-vibrations tsa mochini tse matla haholo ho theha mocheso le ho kopanya litšepe hammoho. Ho thothomela ka potlako ho baka khohlano pakeng tsa likarolo tsa tšepe, e leng se bakang ho futhumatsa le ho qhibiliha ha libaka. Ts'ebetsong ena, li-welders li ka sutumelletsa ka ho toba likarolo tse qhibilihisitsoeng ka har'a tšepe ea motheo ntle le lisebelisoa tse eketsehileng tsa ho tlatsa.
Mefuta ea Tack Weld
Ho na le mefuta e mene ea tack weld. Ho khetha foromo e nepahetseng ho ka thusa ho ntlafatsa ts'ebetso ea welding le boleng. Kahoo, karolo ena e tla li hlalosa ka botlalo.
Square Tack Weld: Mofuta ona oa ho cheseletsa o fana ka motsoako o matla ka ho sebelisa li-welds ka mokhoa oa lisekoere, ho thusa ho kopanya likarolo tse peli tse behiloeng ka mahlakoreng a nepahetseng.
Weld Tack Weld: Mokhoa ona o kenyelletsa ho beha weld e otlolohileng e tsamaisang bolelele bo felletseng ba likotoana tse peli tse kopantsoeng, ho e-na le ho cheselletsa sebaka se ka holimo.
Right Angle Tack : Mofuta ona oa weld o sebelisetsoa ho kopanya likotoana tse peli tsa tšepe tse kopanang ka lehlakoreng la 90-degree. Hangata e sebelisoa ho boloka likotoana tsa tšepe tse ka tlase ho tlhophiso ena ea perpendicular.
Right Angle Corner Tack Weld: Hangata li-welders li sebelisa foromo ena ho thibela ho thehoa ha motsoako o nang le sebōpeho sa T pakeng tsa likaroloana tsa tšepe tsa perpendicular.
Melemo le Melemo ea Tack Welding
Theknoloji ea Tack Welding e fana ka melemo e mengata, empa e boetse e kenyelletsa meeli e itseng.
Melemo ea Tack Weld
- Tokiso ea Nakoana: Likarolo tsa tšepe li tsitsitse ka nakoana ho tsamaisa boemo bo nepahetseng.
- Katleho: E thusa ho ntlafatsa katleho ea mosebetsi bakeng sa taolo ea eona e bonolo
- Theko e tlase: Ha ho bapisoa le mekhoa e meng ea welding, tack welding ha e theko e tlase.
- Wide Application: E loketse lisebelisoa tse ngata 'me e ka sebelisoa bakeng sa likarolo tsa tšepe tsa mefuta e sa tšoaneng.
Mathata a Tack Weld

Tack Welding vs. Spot Welding
Le hoja li-welding tsena tse peli li tšoana, li boetse li na le phapang e itseng. 'Me phapang e kholo lipakeng tsa welding ea tack le welding ke:
- Tack weld ke ts'ebetso ea nakoana ea welding e sebelisetsoang ho boloka likarolo li ntse li le teng, athe spot welding ke ts'ebetso ea resistant welding e etsang hore ho be le tjheseletso ea lehae, e chitja.
- Li-welld tsa tack li nyane ebile ha li teba, athe li-welld tsa spot li matla ebile li tšoarella ho feta.
- Tack welding e atisa ho sebelisoa bakeng sa ho kopanya le ho hokahanya, ha ho cheselletsa sebakeng ho sebelisoa ka bongata
