Joang ho Thibela Mapetso a Nut Welding?

Ho cheselletsa linate ho sebelisoa haholo likarolong tsa likoloi, lisebelisoa tsa lapeng le masela a tšepe. Leha ho le joalo, hang ha ho peperana ho etsahala, hangata ho lebisa ho sebetsa bocha, ho fokotsoa ho sebetsa hantle, tšenyo ea lintho tse bonahalang, esita le ho hana{1}}batch. Lifeme tse ngata li qosa ho se tsitse ha thepa kapa liphoso tsa opareitara, empa taba ea mantlha e bonolo haholoanyane-ho haella ho laola mokhoa oa ho tjheseletsa le lisebelisoa tse sa lekaneng tsa ho tjheseletsa.

1. Welding e sa tsitsang ea Hona joale

Haeba hona joale welding e phahame haholo, sebaka sa linate se chesa haholo, nugget ea weld e atoloha haholo, 'me mapetsong a hlaha nakong ea ho pholile.
Haeba hona joale e le tlase haholo, nugget ha e thehoe hantle, e etsa hore nate e cheselitsoeng e robehe nakong ea ho kenya.

Mathata a atileng mecheng ea khale ea ho tjheseletsa:

• Phetoho ea hona joale e kholo ho feta 10%
• Nako ea karabo e liehang
• Ho se khone ho laola ho kenya mocheso
• Li-welders tsa sejoale-joale tsa MFDC (-frequency inverter) li ka fihlela ±1% botsitso ba hona joale, ho fokotsa haholo likotsi tsa ho phatloha.

2. Khatello e Fosahetseng ea Welding

Khatello e tlase → ho se kopane hantle → khanyetso e phahameng → mocheso o feteletseng oa sebakeng → mapetsong
Khatello e feteletseng → ho fetoha ha linate → khatello ea maikutlo → ho peperana nakong ea kopano

Habohlokoa le ho feta, sekhahla sa khatello se bohlokoa ho feta boleng ba khatello ka boeona.

Li-welders tse tsoetseng pele li fana ka:

• Maikutlo a-ka nako ea sebele
• Mananeo a-a maemo a mangata
• Matšeliso a matla a ikemetseng
• Sena se etsa bonnete ba hore nate e lula e lutse e tiile nakong eohle ea ts'ebetso ea welding.

3. Boemo bo bobe ba Electrode

Haeba sekoahelo sa electrode se koaleha kapa se sa lekana, phello ke:

• Liphetoho tsa khanyetso
• Kabo e sa lekaneng ea mocheso
• Nugget e fokolang ea weld
• Mapetso{0}a manyenyane sebakeng se amehileng-

Lintlha tsa indasteri li bonts'a 32% ea mapetso a ho cheselletsa linate a bakoa ke ho roala ha electrode.

1. Optimize Welding Parameters

Ka tlase ho na le liparamente tsa motheo tse khothaletsoang bakeng sa linate tsa M6–M10:

Seseteme e nepahetseng e phahameng{{0}e tlameha ho kenyelletsa:

• Tlhokomelo ea nako-ea sebele
• 1 ms{1}}taolo ea maikutlo a boemo
• Matšeliso a iketsang bakeng sa mamello ea lintho tse bonahalang

Ka litsamaiso tsena, ts'ebetso ea weld e ka ntlafala ka 40% kapa ho feta.

2. Tlhokomelo ea Electrode (Bohlokoa Bakeng sa Thibelo ea Crack)

Ts'ebetso e khothalelitsoeng:

• Hlahloba li-electrode tse ling le tse ling tse 50-100
• Phetoho ha ho senyeha kapa ho senyeha ho bonoa
• Etsa tlhahlobo ea li-electrode tsa letsatsi le letsatsi
• Sebelisa li-electrode tsa CuCrZr ho eketsa nako ea bophelo 2-3 ×

Ho boloka li-electrode li le boemong bo botle feela ho ka fokotsa ho phatloha ka 30-50%.

3. Workpiece Surface Treatment

Likotsi tsa Crack li eketseha haholo ha bokaholimo bo na le:

• Oli kapa mafura
• Mafome kapa oxide layers
• Mongobo
• Plating e sa leka-lekaneng (mohlala, zinki, nickel)

Mehato e sisintsweng ya kalafo:

• Sebelisa joala kapa lisebelisoa tsa ho hloekisa ho tlosa oli
• Ho roala lehlabathe ho bobebe kapa ho borashe haeba oxidation e le teng
• Kamehla boloka bokaholimo bo omme 'me bo hloekile

Tokiso e nepahetseng ea bokaholimo e matlafatsa matla a weld ka 15-25%.

4. Sebelisa Khatello e Lekaneng Pele-Pele ho Welding

Khatello ea pele{0}e thusa:

• Tsitsisa khanyetso ea ho kopana
• Theha nugget e tšoanang ea weld
• Thibela mocheso o feteletseng le mapetso a manyane-

Mechini ea sejoale-joale ea welding e fana ka:

• Khatello{{0}pele / Welding Pressure / Hold Pressure - 3-taolo ea sethala
• Tokiso-ea nako ea sebele
• Puseletso ea bophahamo ba linate e iketsang

Ha ho bapisoa le litsamaiso tsa matsoho, sekhahla sa ho phatloha se ka fokotsoa ka 70%.

1. Haha Laeborari e Tloaelehileng ea Parameter

Hlophisa ka boholo ba linate, kereiti, poleiti, le thepa:

• Tšepe ea carbon M6/M8/M10
• Linate tsa tšepe tse sa hloekang
• Zinc-matokomane a patiloeng kapa a nickel{1}}a pentiloeng

Boemo ba maemo bo ntlafatsa katleho ea phetoho ka 20-30%.

2. Theha Tsamaiso ea Tsamaiso ea Electrode

Phethahatsa:

• Litlaleho tsa tšebeliso ea bophelo bohle ba electrode
• Tlhahlobo ea sebopeho sa electrode ea beke le beke
• Teko ea ho phalla ha metsi a pholileng (E kholo ho feta kapa e lekana le 4 L/min)
• Alamo e fokolang ea bophara ba li-electrode

Sena se thibela ho theoha ho sa hlokahaleng le liphoso tsa batch.

3. Sebelisa SPC (Taolo ea Ts'ebetso ea Lipalopalo) Moleng oa Tlhahiso

Latela tse latelang:

• Ho feto-fetoha ha hona joale
• Khatello curve botsitso
• Weld tensile matla
• Sekhahla sa spatter

SPC e thusa ho lemoha pele ho hoholeha pele mefokolo e bokellana.

4. Tsamaiso ea Koetliso ea Basebetsi

Lihlooho tsa koetliso li lokela ho kenyelletsa:

• Ho khetha li-electrode tse nepahetseng
• Ho hloaea deformation ea linate
• Ho fetola li-parameter tsa welding
• Ho hlahloba liphoso tse tloaelehileng tsa weld

Ka basebetsi ba koetlisitsoeng, botsitso ba mohala ka kakaretso bo eketseha ka 20% kapa ho feta.

Qetello

Ka ho sebelisa lisebelisoa tsa sejoale-joale tsa tjheseletsa le ho etsa taolo e tloaelehileng ea ts'ebetso:

• Sekhahla sa Crack se fokotseha ka 80-95%
• Matla a weld a ntlafala ka 30%+
• Sekhahla sa ts'ebetso se theoha ka 40-60%
• Bokhoni ba mohala bo eketseha ka 15-25%
