Muaj pes tsawg theem ntawm cov txheej txheem vuam ntawm qhov nruab nrab zaus qhov chaw vuam tshuab muaj?

Koj puas paub tias muaj pes tsawg theem koom nrog hauv cov txheej txheem vuam ntawm qhov nruab nrab zaus qhov chaw vuam tshuab? Niaj hnub no, tus editor yuav muab cov ncauj lus qhia ntxaws ntxaws rau cov txheej txheem vuam ntawm qhov nruab nrab zaus qhov chaw vuam tshuab. Tom qab mus dhau ntau theem no, nws yog lub voj voog vuam ntawm qhov nruab nrab zaus qhov chaw vuam tshuab.

IF inverter chaw welder

1. Ua lub siab preloading ua ntej lub hwj chim rau.

Lub hom phiaj ntawm lub sijhawm preloading yog ua kom ze ze ntawm qhov chaw welded, ua rau cov yas deformation ntawm qhov chaw ntawm qhov chaw sib cuag, ua rau cov oxide zaj duab xis rau saum npoo, thiab ua kom muaj kev sib cuag ruaj khov. Yog tias qhov siab qis dhau lawm, tsuas yog ob peb qhov protruding yuav ua rau kev sib cuag, ua kom muaj kev sib cuag loj. Los ntawm qhov no, cov hlau yuav yaj sai sai ntawm qhov chaw sib cuag, txaws tawm hauv daim ntawv ntawm cov sparks, thiab nyob rau hauv cov xwm txheej hnyav, qhov welded ib feem lossis electrode yuav raug hlawv. Vim lub thickness thiab siab rigidity ntawm cov welded qhov chaw, qhov zoo ntawm cov welded qhov chaw yog tsis zoo. Yog li ntawd, txhawm rau ua kom cov welded qhov chaw nyob sib ze thiab ruaj khov ntawm qhov chaw vuam, cov tam sim no ntxiv tuaj yeem nce ntxiv thaum lub sij hawm nias ua ntej lossis thaum lub sij hawm nias ua ntej. Nyob rau lub sijhawm no, lub siab nias ua ntej yog feem ntau 0.5-1.5 npaug ntawm lub siab ib txwm, thiab qhov ntxiv tam sim no yog 1/4-12 ntawm vuam tam sim no.

2. Siv hluav taws xob cua sov.

Tom qab nias ua ntej, qhov welded qhov chaw tuaj yeem welded nruj nreem. Thaum lub vuam tsis raug, cov hlau ib txwm pib yaj ntawm qhov chaw sib cuag ntawm ob qhov chaw welded ntawm electrode clamping txoj hauj lwm, tsis tas yuav nthuav dav, maj mam tsim cov molten nucleus. Nyob rau hauv lub siab thaum lub sij hawm welding, lub molten nucleus crystallizes (thaum lub sij hawm vuam), tsim ib tug muaj zog daim ntawv cog lus ntawm ob welded qhov chaw.

3. Forging thiab nias.

Cov theem no tseem hu ua qhov txias crystallization theem, uas txhais tau hais tias tom qab cov tub ntxhais molten mus txog qhov tsim nyog thiab loj, qhov vuam tam sim no raug txiav tawm, thiab cov tub ntxhais molten txias thiab crystallizes nyob rau hauv siab. Lub molten core crystallization tshwm sim hauv cov yeeb yaj kiab hlau kaw thiab tsis tuaj yeem cog lus ywj pheej thaum crystallization. Los ntawm kev siv txoj kev no, cov hlau crystallized tuaj yeem ua kom nruj ua ke yam tsis muaj qhov shrinkage lossis tawg, cia cov hlau molten crystallize tag nrho ua ntej siv.
