i-welding joint process of steel space frame

Umphezulu we-weld awuyi kuba neentanda okanye iziphene.I-welds yokuqala kunye neyesibini ayiyi kuba ne-surface pores, i-slag clips, i-arc pit cracks, i-arc abrasion kunye nezinye iziphene.Kwaye i-weld yebakala lokuqala ayinakuluma, ingagcwali, i-shrinkage yeengcambu kunye nezinye iziphene.Ubungakanani bokuhlolwa: I-10% yamacandelo afanayo aya kuhlolwa, kwaye angabi ngaphantsi kwe-3;yamacandelo ahloliweyo, uhlobo ngalunye lwe-weld luya kuhlolwa nge-5% ngamanani amaqhekeza, kwaye kungabi ngaphantsi kwe-1;Ukuhlolwa kwendawo yonke akuyi kuba ngaphantsi kwe-10. Indlela yokuhlola: jonga okanye usebenzise iglasi yokukhulisa, igeyiji yeweld kunye nentsimbi yegeji, kunye novavanyo lokungena okanye lwemagnethi.

Iinkcukacha zeMveliso

Iithegi zeMveliso

Izinto zokudibanisa i-welding kufuneka zihambelane nesiseko sesinyithi.Xa amabakala amabini entsimbi adityanisiweyo, i-electrode okanye ucingo oluhambelana nenqanaba lentsimbi elisezantsi lisetyenziswa.Udibaniso oludityanisiweyo kunye nomthwalo oguquguqukayo othe ngqo okanye ipleyiti eshinyeneyo ebalulekileyo yokuwelda kufuneka isebenzise i-electrode ye-hydrogen ephantsi, efana ne-E4315, E4316, E5015, E5016 kunye nezinye iimodeli. Iingubo ezithintela umlilo kufuneka zibe yimveliso ephumelele uvavanyo lwe-arhente yovavanyo lwesizwe kwaye iye ivunywe lisebe lomlilo, kwaye kufuneka ihambelane ne-primer.Ukusebenza, ukugubungela ubukhulu kunye neemfuno zomgangatho weengubo ezikhethiweyo zomlilo ezikhethiweyo kufuneka zihambelane nomgangatho wangoku welizwe "Ii-Fireproof Coatings for Steel Structures" (GB14907-2018) kunye nomgangatho wangoku wesizwe "I-Tekhnoloji yeSicelo seTekhnoloji yoMlilo kwiiNdawo zeNsimbi" (CECS24) -2020).

Ukuhlolwa komgangatho we-welding seam yezakhelo zendawo kufuneka zihlangabezane neemfuno zomgangatho wesibini ezichazwe kwi-<> (GB50205-2020).Umgangatho womgangatho we-weld uya kuhambelana nomgangatho wangoku wesizwe "iKhowudi ye-Welding of Steel Structures" GB 50661 Indlela yokuhlola iya kuhambelana nomgangatho wangoku welizwe "Ikhowudi yoKwamkeleka koMgangatho woKwakha woBunjineli beSityeli" GB 50205. Kwi-butt iiwelds ezinobunzima obungaphantsi kwe-6mm, ukufumanisa impazamo ye-ultrasonic akuyi kusetyenziswa ukumisela umgangatho we-weld quality.6.Xa umbhobho wentsimbi kunye nepleyiti yokutywina kunye nentloko yekhowuni zenza intonga, i-butt welds kuzo zombini iziphelo ziyi-welds zokungena ezigcweleyo.
