Zotsatira za Butt Joint Groove Form pa Laser Arc Composite Welding ya Medium and Thick Plate

01 Kodi acholumikizira cholumikizidwa

Cholumikizira cholumikizidwa chimatanthauza cholumikizira pomwe zida ziwiri kapena zingapo zogwirira ntchito zimalumikizidwa pogwiritsa ntchito kuwotcherera. Cholumikizira cholumikizidwa cha kuwotcherera cholumikizidwa chimapangidwa ndi kutentha kwapafupi kuchokera ku gwero lotentha kwambiri. Cholumikizira cholumikizidwacho chimakhala ndi malo olumikizirana (malo olumikizirana), mzere wolumikizirana, malo okhudzidwa ndi kutentha, ndi malo achitsulo, monga momwe chithunzichi chikusonyezera.

02 Kodi cholumikizira matako n'chiyani?

Kapangidwe kowotcherera komwe kamagwiritsidwa ntchito kwambiri ndi cholumikizira pomwe zigawo ziwiri zolumikizana zimawotcherera mu mzere umodzi kapena arc pakati pa cholumikiziracho. Khalidwe lake ndi kutentha kofanana, mphamvu yofanana, komanso kosavuta kuonetsetsa kuti kuwotcherera kuli bwino.

03 Kodi amlatho wowotcherera

Pofuna kuonetsetsa kuti malo olumikizirana olumikizidwa alowa bwino komanso kuti zinthu zikuyenda bwino, ndikuchepetsa kusintha kwa malo olumikizirana, malo olumikizirana a zigawo zolumikizidwa nthawi zambiri amakonzedwa kale m'mawonekedwe osiyanasiyana asanalumikizane. Ma groove osiyanasiyana ndi oyenera njira zosiyanasiyana zolumikizirana komanso makulidwe a groove. Mitundu yodziwika bwino ya groove ndi iyi: Yokhala ndi mawonekedwe a I, Yokhala ndi mawonekedwe a V, Yokhala ndi mawonekedwe a U, Yokhala ndi mawonekedwe a V, ndi zina zotero, monga momwe zasonyezedwera pachithunzichi.

Mitundu yodziwika bwino ya malo olumikizira matako

04 Mphamvu ya Butt Joint Groove Form paKuwotcherera kwa Laser Arc Composite

Pamene makulidwe a chogwirira ntchito cholumikizidwa akuwonjezeka, kukwaniritsa kulumikiza mbali imodzi ndi kupanga mbale zapakati ndi zokhuthala mbali ziwiri (mphamvu ya laser <10 kW) nthawi zambiri kumakhala kovuta. Nthawi zambiri, njira zosiyanasiyana zolumikizira ziyenera kutsatiridwa, monga kupanga mitundu yoyenera ya groove kapena kusunga mipata ina ya docking, kuti pakhale kulumikiza mbale zapakati ndi zokhuthala. Komabe, pakulumikiza kwenikweni, kusungira mipata ya docking kudzawonjezera zovuta za zida zolumikizira. Chifukwa chake, kapangidwe ka groove kamakhala kofunikira panthawi yolumikizira. Ngati kapangidwe ka groove sikoyenera, kukhazikika ndi kugwira ntchito bwino kwa welding kudzakhudzidwa kwambiri, ndipo kumawonjezeranso chiopsezo cha zolakwika za welding.

(1) Kapangidwe ka groove kamakhudza mwachindunji ubwino wa msoko wothira weld. Kapangidwe koyenera ka groove kangathandize kuonetsetsa kuti chitsulo chothira weld chadzazidwa mokwanira mu msoko wothira weld, zomwe zimachepetsa kuwonongeka kwa stroove.

(2) Kapangidwe ka mzere wa payipi kamakhudza momwe kutentha kumasamutsidwira, zomwe zingathandize kutsogolera kutentha bwino, kukwaniritsa kutentha ndi kuzizira kofanana, komanso kuthandiza kupewa kusintha kwa kutentha ndi kupsinjika kotsalira.

(3) Kapangidwe ka msoko kadzakhudza mawonekedwe a msoko wa weld, ndipo izi zidzapangitsa kuti mawonekedwe a msoko wa weld akhale ogwirizana kwambiri ndi zofunikira zinazake, monga kuya ndi m'lifupi mwa kulowa kwa weld.

(4) Fomu yoyenera ya groove ingathandize kukhazikika kwa kuwotcherera ndikuchepetsa zochitika zosakhazikika panthawi yowotcherera, monga kupopera ndi zolakwika zodulidwa.

Monga momwe zasonyezedwera pa Chithunzi 3, ofufuza apeza kuti kugwiritsa ntchito laser arc composite welding (laser power 4kW) kungadzaze groove m'magawo awiri ndi ma pass awiri, zomwe zimapangitsa kuti ntchito yowotcherera ikhale yabwino; Kuwotcherera kopanda chilema cha 20mm makulidwe a MnDR kunatheka pogwiritsa ntchito laser arc composite welding yokhala ndi ma layer atatu (laser power ya 6kW); Laser arc composite welding idagwiritsidwa ntchito kuwotcherera chitsulo chotsika cha kaboni cha 30mm makulidwe m'magawo angapo ndi ma pass, ndipo mawonekedwe a cholumikizira chowotcherera anali okhazikika komanso abwino. Kuphatikiza apo, ofufuza apeza kuti m'lifupi mwa ma groove a rectangular ndi ngodya ya ma groove ooneka ngati Y zimakhudza kwambiri mphamvu ya malo. Pamene m'lifupi mwa rectangular groove ndi≤4mm ndipo ngodya ya mlatho wooneka ngati Y ndi≤60 °, mawonekedwe a msoko wa weld akuwonetsa ming'alu yapakati ndi makoma am'mbali, monga momwe chithunzichi chikusonyezera.

Zotsatira za Groove Form pa Cross Section Morphology ya Welds

Mphamvu ya Kukula kwa Groove ndi Angle pa Cross Section Maonekedwe a Welds

Chidule cha 05

Kusankha mawonekedwe a groove kuyenera kuganizira mokwanira zofunikira pa ntchito yowotcherera, mawonekedwe a zinthu, ndi mawonekedwe a njira yowotcherera ya laser arc composite. Kapangidwe koyenera ka groove kangathandize kukonza bwino ntchito yowotcherera ndikuchepetsa chiopsezo cha zolakwika zowotcherera. Chifukwa chake, kusankha ndi kapangidwe ka groove ndi chinthu chofunikira kwambiri musanawotchetse mbale zapakati ndi zokhuthala pogwiritsa ntchito laser arc.
