Lub workpiece puas hnyav heev thaum lub sij hawm vuam? 3 Txoj Kev Kho Kom Yooj Yim Kom daws tau

 I. Kev soj ntsuam ntawm qhov ua rau ntawm Workpiece Deformation

Workpiece deformation yog ib qho teeb meem tshwm sim nyob rau hauv qhov chaw - vuam txheej txheem. Qhov no feem ntau yog vim cov cua sov tsim thaum lub sij hawm vuam, uas ua rau qhov kub thiab txias hauv qhov chaw ua haujlwm thiab ua rau cov khoom tsis sib xws. Tsis tas li ntawd, cov yam ntxwv xws li cov vuam tam sim no ntau dhau, lub sijhawm vuam ntev ntev, thiab tsis ruaj ntseg workpiece clamping tuaj yeem ua rau qhov deformation ntau dua. Yog tias qhov teeb meem no tsis daws tau zoo, nws yuav tsis tsuas yog cuam tshuam rau qhov zoo ntawm lub workpiece tab sis kuj ua rau txo qis hauv vuam lub zog, yog li cuam tshuam rau tag nrho cov kev ua tau zoo ntawm cov khoom.

 II. Adjustment Skill Ib: Optimizing Welding Parameters

Kev teeb tsa ntawm vuam tsis yog qhov tseem ceeb rau kev vuam zoo. Ua ntej, nws yog ib qho tsim nyog yuav tsum tau kho qhov vuam tam sim no raws li cov khoom siv, thickness ntawm lub workpiece, thiab vuam yuav tsum. Ntau dhau tam sim no tuaj yeem yooj yim ua rau cov cua sov siab, ua rau muaj kev kub ntxhov hauv cheeb tsam thiab deformation ntawm workpiece; Tam sim no tsis txaus yuav ua rau tsis muaj kev ruaj ntseg vuam. Qhov tsim nyog tam sim no feem ntau tuaj yeem txiav txim siab los ntawm kev sim lossis xa mus rau cov ntaub ntawv tseem ceeb. Qhov thib ob, vuam lub sij hawm kuj yuav tsum tau tswj kom meej. Lub sijhawm vuam ntev ntev tuaj yeem ua rau muaj cua sov ntau dhau, ua rau muaj kev pheej hmoo ntawm deformation; luv luv lub sij hawm welding yuav ua tsis tau ib tug zoo weld point. Los ntawm kev kho lub sijhawm vuam, cov cua sov tuaj yeem sib npaug mus rau qhov chaw vuam, yog li txo qhov ua haujlwm ntawm qhov deformation. Tsis tas li ntawd, welding voltage kuj tuaj yeem hloov kho kom tsim nyog los xyuas kom meej qhov ruaj khov ntawm cov txheej txheem vuam.

 III. Kev Kho Hniav Ob: Txhim Kho Workpiece Clamping Method

Txoj kev clamping ntawm lub workpiece thaum lub sij hawm vuam txheej txheem kuj muaj feem xyuam rau cov degree ntawm deformation. Yog hais tias lub workpiece tsis ruaj ntseg clamped, nws yog feem ntau hloov los yog deformation nyob rau hauv qhov kev txiav txim ntawm thermal stress thaum lub sij hawm vuam. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tau xaiv cov clamps tsim nyog los xyuas kom meej qhov ruaj khov ntawm lub workpiece thaum vuam. Tshwj xeeb vuam clamps tuaj yeem siv tau, uas feem ntau muaj qhov zoo rigidity thiab clamping quab yuam thiab tuaj yeem txhim kho lub workpiece zoo. Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them rau txoj haujlwm clamping thiab quab yuam thaum clamping lub workpiece. Txoj hauj lwm clamping yuav tsum nyob ze rau qhov chaw vuam raws li qhov ua tau kom txo qis kev vibration ntawm lub workpiece thaum vuam; lub clamping quab yuam yuav tsum yog nruab nrab, kom ntseeg tau tias lub workpiece ruaj ruaj tsis ua rau compression ntau deformation. Tsis tas li ntawd, cov kev pabcuam pabcuam tuaj yeem teeb tsa rau ntawm qhov chaw ua haujlwm txhawm rau txhim kho nws cov rigidity thiab txo qhov muaj peev xwm ntawm deformation.

IV. Adjustment Skill Peb: Txais Siv Welding Sequence

Lub vuam ntu tseem muaj qee yam cuam tshuam rau workpiece deformation. Ib qho laj thawj kev sib txuas ua ke tuaj yeem ua rau cov cua sov faib ntau dua thiab txo qhov tshwm sim ntawm qhov chaw overheating hauv lub workpiece. Piv txwv li, thaum welding loj - loj workpieces, segmented rov qab - stepping vuam txoj kev yuav siv tau. Txoj kev no suav nrog kev faib tag nrho cov vuam ntev rau hauv ob peb ntu. Tom qab txhua ntu yog welded, lub vuam teeb txav rov qab los ntawm ib qho kev ncua deb ua ntej mus rau ntu tom ntej. Qhov no tso cai rau cov cua sov yuav maj mam hloov rov qab thaum lub sij hawm vuam txheej txheem, tsis txhob kub siab nyob ze ntawm lub vuam pib taw tes thiab yog li txo deformation ntawm lub workpiece ntawm qhov chaw pib. Rau workpieces nrog cov duab complex, symmetrical vuam kuj siv tau. Vuam symmetrically los ntawm qhov nruab nrab ntawm lub workpiece mus rau ob sab tuaj yeem ua rau cov cua sov faib rau ob sab ntawm lub workpiece yeej zoo ib yam, txo qhov deformation los ntawm qhov tsis sib xws. Nyob rau hauv qhov tseeb welding, qhov tsim nyog vuam ib ntus yuav tsum tau flexibly xaiv raws li cov duab tshwj xeeb thiab cov qauv ntawm lub workpiece.

Los ntawm kev siv peb qhov kev hloov kho saum toj no, qhov teeb meem loj ntawm workpiece deformation thaum qhov chaw - vuam tuaj yeem daws tau zoo. Txawm li cas los xij, xaiv qhov chaw ua haujlwm siab - welder kuj yog ib qho tseem ceeb hauv kev ua kom cov vuam zoo. PDKJ welders, nrog rau lawv cov cuab yeej vuam siab heev thiab kev ua haujlwm ruaj khov, tuaj yeem muab kev txhim khu kev lag luam rau koj. Lawv tau nruab nrog cov kev tswj xyuas qhov tseeb uas tuaj yeem ua tau raws li cov kev xav tau ntawm cov khoom sib txawv. Nyob rau tib lub sijhawm, lawv cov txheej txheem vuam zoo tsim tau tuaj yeem txo cov cua sov tawm thaum lub sijhawm vuam, txo qhov kev pheej hmoo ntawm workpiece deformation. Xaiv PDKJ welders los ua kom koj cov vuam ua haujlwm yooj yim dua thiab ua haujlwm zoo dua.

Yog tias koj xav tau lub tshuab vuam, thov hu rau Ms. Zhao
