 Spot Welding yog dab tsi?

Spot welding yog cov txheej txheem hlau sib koom ua ke uas lub siab raug siv rau cov hlau ua haujlwm los ntawm sab sauv thiab qis electrodes, thiab cov hluav taws xob tam sim no ua rau lawv sov rau lub sijhawm teem, ua rau cov hlau vuam ntawm cov ntsiab lus sib cuag. Cov electrodes feem ntau yog ua los ntawm tooj liab vim nws cov thermal conductivity thiab tsis tshua muaj zog. Thaum tam sim no dhau los ntawm cov electrodes thiab cov hlau workpieces, cua sov yog concentrated ntawm cov ntsiab lus sib cuag, yaj lawv mus rau hauv lub xeev yas. Tam sim no nres, tab sis lub siab yog tswj, sib txuas cov ntsiab lus sib txuas ua ke. Spot welds yog me me, nrog rau txhua qhov chaw weld txoj kab uas hla ntawm li 3 mus rau 20 mm.

Spot Welding ua haujlwm li cas?

Peb faib qhov chaw vuam txheej txheem rau hauv plaub kauj ruam: teeb tsa, tso cov khoom ua haujlwm, siv lub zog, thiab dhau tam sim no.

Kev teeb tsa Parameters

Ib kauj ruam tseem ceeb hauv qhov chaw welding yog teeb tsa qhov ntsuas qhov ntsuas. Lub tshav kub tsim thaum lub sij hawm vuam yog feem ntau txiav txim los ntawm peb tsis: tam sim no, tsis kam, thiab lub sij hawm. Kev sib raug zoo ntawm cov kev ntsuas no yog qhia los ntawm cov kab zauv hauv qab no:

Q = I² Rt

Q = tshav kub generated

Kuv = welding tam sim no

R = tsis kam ntawm electrode

T = duration of current flow

Cov kev ntsuas no cuam tshuam ib leeg thiab txiav txim siab qhov vuam zoo. Tam sim no muaj kev cuam tshuam loj tshaj plaws; nws tus nqi squared hauv qhov sib npaug cuam tshuam rau cov cua sov tsim.
