01 Kodi awelded olowa
Cholowa chowotcherera chimatanthawuza cholumikizira pomwe zida ziwiri kapena zingapo zimalumikizidwa ndi kuwotcherera. Chowotcherera chophatikizika cha fusion welding chimapangidwa ndi kutenthetsa komweko kuchokera kugwero la kutentha kwambiri. Cholumikizira chowotcherera chimakhala ndi fusion zone (weld zone), mzere wophatikizira, malo omwe akhudzidwa ndi kutentha, ndi zitsulo zoyambira, monga momwe zikuwonekera pachithunzichi.
02 Kodi cholumikizira matako ndi chiyani
Chowotcherera chomwe chimagwiritsidwa ntchito nthawi zambiri ndi cholumikizira pomwe magawo awiri olumikizana amawotcherera mu ndege imodzi kapena arc pakatikati pa olowa. Makhalidwe ndi kutentha yunifolomu, mphamvu yunifolomu, ndi zosavuta kuonetsetsa kuwotcherera khalidwe.
03 Kodi akuwotcherera poyambira
Pofuna kuonetsetsa kuti malowedwe ndi ubwino wa mfundo welded, ndi kuchepetsa kuwotcherera mapindikidwe, mafupa a mbali welded zambiri Pre kukonzedwa mu akalumikidzidwa zosiyanasiyana pamaso kuwotcherera. Mitundu yosiyanasiyana yowotcherera ndiyoyenera njira zosiyanasiyana zowotcherera komanso makulidwe a weldment. Mitundu yodziwika bwino ya groove ndi: I-woboola, V-woboola, U-mawonekedwe, unilateral V-mawonekedwe, etc., monga momwe chithunzichi chikusonyezera.
Mitundu yodziwika bwino yamagulu a matako
04 Chikoka cha Butt Joint Groove Fomu paKuwotcherera kwa Laser Arc Composite
Pamene makulidwe a workpiece welded ukuwonjezeka, kukwaniritsa kuwotcherera limodzi mbali imodzi ndi iwiri mbali kupanga mbale sing'anga ndi wandiweyani (laser mphamvu<10 kW) nthawi zambiri zimakhala zovuta. Nthawi zambiri, njira zosiyanasiyana zowotcherera zimafunika kutsatiridwa, monga kupanga mafomu oyenerera a groove kapena kusungitsa mipata ina yotsekera, kuti akwaniritse kuwotcherera kwa mbale zapakati ndi zokhuthala. Komabe, pakuwotcherera kwenikweni, kusungitsa mipata yama docking kumawonjezera zovuta zowotcherera. Chifukwa chake, mapangidwe a groove amakhala ofunikira panthawi yowotcherera. Ngati kamangidwe ka groove sikoyenera, kukhazikika komanso kugwira ntchito bwino kwa kuwotcherera kumakhudzidwa kwambiri, komanso kumawonjezera chiopsezo cha zolakwika zowotcherera.
(1) Maonekedwe a groove amakhudza mwachindunji mtundu wa weld seam. Kapangidwe koyenera ka groove kumatha kuwonetsetsa kuti chitsulo chowotcherera chadzaza kwathunthu mumsoko wowotcherera, kuchepetsa kupezeka kwa zolakwika zowotcherera.
(2) Maonekedwe a geometric a groove amakhudza momwe kutentha kumasunthidwira, komwe kungathe kutsogolera kutentha, kukwaniritsa kutentha kofanana ndi kuzizira, ndikuthandizira kupewa kutentha kwa kutentha ndi kupanikizika kotsalira.
(3) The poyambira mawonekedwe adzakhudza mtanda-Sectional kapangidwe kake wa weld msoko, ndipo zidzachititsa kuti mawonekedwe a mtanda-Sectional kapangidwe ka weld msoko kukhala mogwirizana ndi zofunika zenizeni, monga kuwotcherera malowedwe kuya ndi m'lifupi.
(4) Mawonekedwe oyenera a groove amatha kusintha kukhazikika kwa kuwotcherera ndikuchepetsa zochitika zosakhazikika panthawi yowotcherera, monga kuwotcherera ndi zolakwika.
Monga momwe tawonetsera pa Chithunzi 3, ofufuza apeza kuti kugwiritsa ntchito laser arc composite kuwotcherera (laser mphamvu 4kW) kungathe kudzaza poyambira mu zigawo ziwiri ndi kudutsa ziwiri, kuwongolera bwino kuwotcherera; Kuwotcherera kwaulere kwa 20mm wandiweyani wa MnDR kunapezedwa pogwiritsa ntchito kuwotcherera kophatikiza kwa laser arc kompositi yamitundu itatu (laser mphamvu ya 6kW); Kuwotcherera kopangidwa ndi laser arc kunagwiritsidwa ntchito powotcherera chitsulo cha 30mm wandiweyani wa kaboni wocheperako m'magawo angapo ndi ma pass, ndipo mawonekedwe amtundu wagawo lolumikizana anali okhazikika komanso abwino. Kuphatikiza apo, ofufuza apeza kuti m'lifupi mwa mizere yamakona anayi ndi mbali ya ma grooves ooneka ngati Y amakhudza kwambiri kuletsa kwa malo. Pamene m'lifupi mwa amakona anayi poyambira ndi≤4mm ndipo ngodya ya groove yooneka ngati Y ndi≤60 °, mawonekedwe amtundu wamtundu wa weld seam amawonetsa ming'alu yapakati ndi makoma am'mbali, monga momwe tawonetsera pachithunzichi.

Mphamvu ya Groove Width ndi Angle on the Cross Section Morphology of Welds
05 Chidule
Kusankhidwa kwa mawonekedwe a groove kumafunika kuganizira mozama zofunikira za ntchito yowotcherera, mawonekedwe azinthu, ndi mawonekedwe a laser arc composite kuwotcherera. Kapangidwe koyenera ka groove kumatha kupititsa patsogolo kuwotcherera komanso kuchepetsa chiopsezo cha zovuta zowotcherera. Chifukwa chake, kusankha ndi kupanga mawonekedwe a groove ndichinthu chofunikira kwambiri pamaso pa kuwotcherera kwa laser arc kwa mbale zapakati ndi wandiweyani.
