Hlau Vuam, zoo thiab hom

Lug siv nyob rau hauv kev tsim kho thiab tsev neeg tau txais welds. hlau vuam muaj zoo dua lwm txoj kev koom nrog qhov chaw:

- cov ntaub ntawv uas cov nyiaj khaws tseg, yog tsis muaj yuav tsum tau siv ntxiv fasteners;

- ntau txhim khu kev qha kev tsim kho yog tau, tag nrho cov welded pob qij txha yog tsim los rau cov uas twb muaj lawm load;

- ntau muaj kuab siv ntawm cov khoom no tsis tsim nyog raws li nyob rau hauv lub casting pwm, tsim kom muaj sprues, thiab nrog machining nyiaj muab ntxiv;

- kom txhob muaj cov complexity ntawm raug qhov chaw thiab lug ntawm ntshav vim muaj kuab siv ntawm yam thickness ntawm cov hlau.

Hlau vuam yog ua xws vuam uas siv: electrodes, hlau rods. Nyob rau hauv cov ntaub ntawv yuav tsum tau welded, tej zaum lawv yuav ua los ntawm cov pa roj carbon steels, txhuas alloys, tungsten uas tsis yog-consumable electrode, lub electrodes rau txuas lub hlau.

Lub ntsiab yam ntawm welds: ces kaum, bungy, tees, pob tw, Splices, nrog plug (hu vuam).

Cov kev ua tebchaw:

- phau ntawv vuam ntawm hlau - yog dab tsi los yog muaj sib sib zog nqus allergic;

- txiav - submerged arc, nyob rau hauv cov pa roj carbon dioxide, electroslag;

- semi-automatic - nyob rau hauv shielding roj thiab submerged arc.

Raws li cov qauv ntawm cov pob qij txha qhov chaw nyob rau hauv qhov chaw, lawv yog mounted, ntsug, kab rov tav thiab hauv qab. Nyob rau hauv ntev - khoom thiab tawg. Nrog plug thiab sib quas ntus welds yog siv nyob rau hauv cov kev sib txuas uas tsis yuav tsum tau sib khi. Cov khoom pob qij txha yog siv yog tias yuav tsum los ntawm lub tsim ntaub ntawv. Thaum nws yog tsim nyog los ua ib tug tag nrho allergic, lub weld kuaj txia los ntawm ib tug ultrasonic txoj kev, los yog kerosene.

taub qab-Vuam hlau ntawm mus txog 8 hli nyob rau hauv thickness yog ua tsis txiav npoo. Saum toj no yog unilateral los yog ob sab sib dho tej npoo, nyob ntawm seb cov ntaub ntawv uas tuab thiab cov qauv hauj lwm.

Sheet hlau vuam yog ua longitudinal los yog transverse nqaws thawj boil lub thib ob thiab ces ua ntej. Lub leeg yog thov los ntawm cov saum toj kawg nkaus down yuav tsum tsis txhob influx ntawm thaum thov kev pab. Qhov khoob ntawm lub ntsiab yuav tsum tau hais txog lub 1 hli.

Thaum ib tug nyias hlau welding, nyob rau hauv kev txiav txim kom tsis txhob deformation ntawm cov khoom, ua forcible zanevolivanie qauv. Nyob rau hauv tas li ntawd mus no, koj yuav tsum xub ua ntawv thov ib tug tas mus leeg, thiab ces sau rau cov uas ploj lawm qhov chaw. Yuav kom tiv thaiv hlawv ntawm cov hlau, thaum lub ob leeg yuav tsum tau nruj me ntsis kom muaj lub technology thiab siv cov coj tsim nyog electrodes los yog hlau taub. Tag nrho cov taub qab welds yog ua rau cov qhov tso zis ntsia.

Rau cov tsis siv neeg vuam kav dej, ducts, ntshav surfacing ntawv yog siv. Lub thickness ntawm cov welded ntsiab - los ntawm 0.5 hli rau 5 hli. Basic cov ntaub ntawv rau ntshav technology - stainless, galvanized, me me hlau.

Tiv tauj point khub yog siv rau ferrous los yog nonferrous co sib tshooj. Nws yog siv nyob rau hauv qhov siv thiab ua cua, lub haum ntawm cov yeeb nkab xaus nyob rau hauv zus tau tej cov zoo li tus khoom. Yog hais tias hu sib txuas siv cov khoom uas yog yooj yim los mus teeb thiab yooj yim rau siv.
