Ntau tus neeg siv khoom siv thawj zaug tau ntsib tib qhov kev sib tw: lub tshuab tau teeb tsa thiab npaj txhij, tab sis lawv tsis paub meej tias yuav teeb tsa qhov vuam tsis zoo li cas.

Yog hais tias lub vuam tam sim no siab dhau lawm, lub workpiece yuav hlawv. Yog tias lub zog electrode tsawg dhau lawm, cov welds tsis muaj zog tuaj yeem tshwm sim. Lub sijhawm vuam uas luv dhau ua rau tsis txaus fusion, thaum lub sijhawm vuam ntau dhau tuaj yeem ua rau tawg thiab deformation.

Hmoov zoo, feem ntau qhov chaw vuam tsis ua raws li ob peb txoj cai. Thaum koj nkag siab cov kev teeb tsa tseem ceeb, koj tuaj yeem nrhiav qhov tsis zoo rau koj daim ntawv thov.

Kab lus no piav qhia txog cov kev hloov kho qhov chaw vuam ntau tshaj plaws thiab suav nrog cov lus qhia dav dav los pab koj ua tiav lub tshuab teeb tsa sai.

Ⅰ Dab tsi yuav tsum tau hloov kho ntawm Spot Welder?

Txawm hais tias koj siv AC qhov chaw welder lossis qhov nruab nrab zaus inverter qhov chaw vuam, cov kev ntsuas hauv qab no yog qhov tseem ceeb tshaj plaws.

1. Vuam tam sim no

Vuam tam sim no txiav txim siab npaum li cas cov cua sov tsim thaum lub sij hawm vuam.

Yog tias qhov tam sim no qis dhau:

• Tsis muaj welds

• Kev sib koom ua ke tsis zoo

Yog tias qhov tam sim no siab dhau:

• Hlawv-dhau

• Tshaj tawm ntau dhau

• Kev hnav electrode ceev dua

Feem ntau, cov ntaub ntawv tuab yuav tsum tau vuam tam sim no dua.

2. Lub sijhawm vuam

Vuam lub sij hawm yog hais txog ntev npaum li cas cov dej ntws tam sim no.

Yog tias lub sijhawm vuam luv dhau:

• Lub weld nugget tsis ua tiav.

Yog tias lub sijhawm vuam ntev dhau lawm:

• Lub workpiece yuav overheat.

• Deformation yuav tshwm sim.

Ib txoj hauv kev ua tau zoo yog pib nrog lub sijhawm vuam luv dua thiab maj mam nce nws thaum kuaj.

3. Electrode quab yuam

Electrode quab yuam cuam tshuam rau kev sib cuag ntawm electrodes thiab workpiece.

Yog tias lub zog qis dhau:

• Kev sib cuag tsis ruaj khov

• Nce spatter

Yog hais tias lub zog loj heev:

• Tsawg tam sim no ceev

• Txo lub zog weld

Lub zog electrode yuav tsum tau kho raws li cov khoom thickness thiab daim ntawv thov.

4. Electrode Tip condition

Ntau tus neeg ua haujlwm saib xyuas kev kho electrode.

Txawm tias muaj qhov tseeb vuam tsis zoo, hnav cov lus qhia electrode tuaj yeem ua rau:

• Inconsistent weld loj

• Tsis muaj welds

• Nce spatter

Kev hnav khaub ncaws tsis tu ncua lossis hloov cov lus qhia electrode pab tswj cov vuam zoo.

Ⅱ Dab tsi yog Qhov Kev Txiav Txim Rau Kev Kho Vuam Tsis Zoo?

Ib qho kev pom zoo hloov ua ntu zus yog:

1. Teem lub zog electrode.

2. Teem lub sijhawm vuam.

3. Kho qhov vuam tam sim no.

4. Ua ib qho kev xeem weld.

5. Fine-tune qhov parameter raws li cov txiaj ntsig welding.

Ua raws li cov kab ke no ua rau kev hloov pauv sai thiab ua haujlwm tau zoo dua.

Ⅲ Cov lus qhia txog kev hloov kho Parameter rau cov khoom sib txawv
