Spot welding electrode belongs rau chav kawm ntawm kev tiv thaiv vuam electrode. Resistance welding feem ntau yog hais txog kev siv tam sim no los ntawm kev siv vuam thiab kev sib cuag ntawm cov cua sov ua kom sov ua kom sov hauv zos rau qhov chaw vuam, thiab tib lub sij hawm siab vuam txoj kev. Thaum vuam, tsis tas yuav tsum tau sau cov hlau, kev tsim khoom siab, me me deformation ntawm weldparts, yooj yim kom paub automation.
1. Cov kev cai zoo rau qhov chaw vuam pob qij txha
Ua ntej tshaj plaws, qhov sib koom ua ke yuav tsum muaj qee lub zog, uas feem ntau yog nyob ntawm qhov loj ntawm cov molten core (inch thiab vuam nkag), cov hlau microstructure thiab qhov tsis xws luag ntawm cov tub ntxhais molten thiab nws cov cheeb tsam uas muaj cua sov. Lub zog ntawm qhov chaw welded pob qij txha ntawm cov khoom siv hlau feem ntau tsuas yog cuam tshuam nrog qhov loj ntawm cov tub ntxhais molten. Thaum lub sij hawm qhov chaw vuam, vim yog qhov tsis zoo ntawm kev npaj tsis raug (xws li qhov tsis ncaj ncees lawm, lub vojvoog fillet tsis ua raws li qhov yuav tsum tau ua, thiab lwm yam), kev sib dhos tsis zoo ntawm cov khoom, tsis zoo ntawm cov electrode caj npab ntawm lub vuam tshuab, thiab lwm yam., vuam qauv tsis xws luag. raug tshwm sim, thiab qhov tsis xws luag no tseem yuav ua rau muaj teeb meem zoo, thiab txawm tias cov khoom pov tseg. Yog li ntawd, cov ntaub ntawv hlau tsim nyog yuav tsum raug xaiv los ua qhov chaw vuam pob qij txha, xws li tungsten lossis tungsten alloy cov ntaub ntawv.
2. Kev tu thiab hnav khaub ncaws ntawm qhov chaw vuam electrode
Lub voj voog tu electrode yuav tsum nyob ntawm cov khoom siv ntawm cov electrode thiab cov khoom siv vuam. Vuam electrodes ntawm tib cov khoom, cov electrode ntawm AC fais fab mov yog feem ntau yuav kis tau tus electrode ntawm DC fais fab mov.
Yog hais tias lub electrode nto muaj oxides, av thiab hnav me ntsis, nws tuaj yeem polished thiab trimmed nrog ib lub phaj tiaj tiaj nrog cov roj hmab ncoo ntawm daim ntaub emery. Yog tias qhov hnav thiab deformation ntawm electrode nto loj, cov ntaub ntawv tuaj yeem siv los kho; Thaum cov electrode ua rau hnav thiab deformation ntau dua, yuav tsum tau hloov lub electrode tshiab.
Thaum vuam aluminium alloy, electrode nto yog me ntsis oxidized thiab polluted, nws yuav tsum tau ntxuav tam sim ntawd, txwv tsis pub, nws yuav txo tau cov corrosion kuj ntawm aluminium alloy.
Feem ntau qhov chaw vuam electrodes yog ua los ntawm cov khoom siv tungsten tooj liab alloy, uas sib txuas qhov zoo ntawm tungsten thiab tooj liab, xws li kub tsis kam, arc ablation tsis kam, siab zog, hnyav hnyav, zoo hluav taws xob thiab thermal conductivity, yooj yim txiav, thiab hws txias. Yog tias muaj kev xav tau ntawm qhov chaw vuam electrodes zoo, thov hu rau peb ntawm email.
