Kwinkqubo ye-welding eshushu-enyibilikayo yombhobho we-PE, kuyimfuneko ukulawula ngokubanzi umgangatho wayo, ukwenza umsebenzi wokulawula kubaqhubi, izixhobo zoomatshini, izinto zokuwelda kunye nenkqubo ye-welding, ukuxhomekeka kumsebenzi wokuvavanya, kwaye uzame ukunciphisa iintanda ze-welding kunye ne-welding. iintanda.Okwangoku, amashishini okwakha eTshayina akwi-welding eshushu enyibilikayo

Qala ukusebenzisa iteknoloji yokuvavanya i-ultrasonic ukuphumeza umsebenzi ofanelekileyo wokuvavanya, onokufumana ngexesha elifanelekileyo iingxaki zekhwalithi ye-welding ngaphakathi kwimibhobho ye-PE, uthathe amanyathelo asebenzayo okuqhuba ulawulo lomgangatho ngaphambi nangexesha le-welding, kunye nokulawula umgangatho wokwakha ngokuhlola emva kwe-welding.

I-1) Amanyathelo okulawula umgangatho phambi kwe-welding.

Ngaphambi kwe-welding, kuyimfuneko ukwenza umsebenzi omhle ekulawuleni umgangatho, onokuphucula umgangatho womsebenzi.Okokuqala, kubaqhubi be-welding, umgangatho wabo wobugcisa kunye nezakhono kufuneka zilawulwe ngokungqongqo, kwaye kufuneka babe nezatifikethi zesiqinisekiso se-welding.Kwangaxeshanye, kuyimfuneko ukwenza iskim solawulo lomgangatho ogqibeleleyo kunye nokwakha ishishini elikumgangatho ophezulu ngokweemfuno zalo zophuhliso.

Iqela letalente esemgangathweni, ukuze kuphuculwe umgangatho wokwakha.Ukulungiselela imathiriyeli ye-welding, iimfuno ezifanelekileyo zomgangatho wesizwe ziya kuhlangatyezwa.Okwesibini, kwinkqubo yokukhetha izixhobo ze-welding, kuyimfuneko ukuba usebenzise ngokusebenzayo umatshini wokuwelda wombane ozenzekelayo ukuze ube nemisebenzi yembuyekezo ezenzekelayo, ukufudumeza okuzenzekelayo kunye noxinzelelo, umboniso ozenzekelayo wolwazi lwedatha ye-welding, ukuhlolwa ngokuzenzekelayo kunye nokuzimela. ukubeka esweni

Ukufumanisa ngokuzenzekelayo, i-alamu ngokuzenzekelayo kunye neminye imisebenzi yokuxhasa uphuhliso lomsebenzi we-welding.Okwesithathu, kuyimfuneko ukuba ukhethe ngokwesayensi inkqubo ye-welding kwaye uyivavanye.Ngexesha elifanayo, kuyimfuneko ukuqinisekisa ukuba umgangatho we-melt udibana nemimiselo efanelekileyo kwaye akukho ngxaki zomgangatho zivunyelwe.Ekugqibeleni, kwiiparamitha zenkqubo ye-welding, kuyimfuneko ukwenza umsebenzi olungileyo wokuvavanya nokulawula iiparamitha zabo zobushushu.

Ubushushu bokulungiselela bungaphakathi kwe-230 ℃, ukuze kuphuculwe umgangatho wokusebenza kwayo.Ngexesha elifanayo, umgangatho wemibhobho kunye nezixhobo ziya kujongwa ngokubanzi.Emva kokuba umgangatho uhlangabezana neemfuno ezifanelekileyo, i-welding interface iya kulungiswa, unyango lokucoca luya kwenziwa, kwaye i-oxide layer iya kuchithwa.

2) Amanyathelo okulawula umgangatho ngexesha le-welding.

Kumsebenzi we-welding wangempela, kuyimfuneko ukwenza umsebenzi omhle kulawulo lomgangatho, ukunciphisa ukungahambi kakuhle kunye nokwandisa ngokuthe ngcembe inkqubo yayo yokusebenza.Okokuqala, ubushushu bomatshini wokuwelda kufuneka ilawulwe malunga ne-210 ℃ ukwenza lula ukuwelda.Ukongeza, kwimozulu enomoya okanye imvula kunye nekhephu, ayilungele umsebenzi we-welding kwaye unqande ubushushu obugqithisileyo.

Isiganeko esiphantsi.Okwesibini, amagcisa okwakha kufuneka asebenze ngokungqongqo ngokuhambelana nemigaqo efanelekileyo ukuze kuqinisekiswe ukuchaneka kolwazi lwedatha yomsebenzi.Okwesithathu, isibonelelo sokwenza isixhobo kufuneka silawulwe ngaphezu kwe-21mm, kwaye isantya sokusebenza kunye nobushushu kufuneka zilawulwe ngokwesayensi ukunqanda iziphene zokuwelda.Okwesine, i-welding joint idinga ukupholisa phantsi koxinzelelo oluzinzileyo (ukupholisa umoya wendalo).Ayinakushukunyiswa okanye yongezwa uxinzelelo.Okwesihlanu, ngexesha le-welding, kuyimfuneko ukuqinisekisa ukuba ubuso besitya sokufudumala buhlala bucocekile.

3) Amanyathelo okulawula umgangatho emva kwe-welding.

Emva kokugqiba umsebenzi we-welding, ishishini lokwakha kufuneka liqhube lonke uhlolo malunga nokubonakala kweengxenye ze-welding, kwaye sebenzisa indlela yokuhlola ukusika (i-notch yokuhlola isampuli ukuya kwi-5%) ukufumana iingxaki ezikhoyo kumsebenzi welding ngexesha. .Kwangaxeshanye, amagcisa kufuneka enze uvavanyo loxinzelelo kwaye adibanise uhlolo olungacwangciswanga kunye nohlolo olubanzi, njengomthamo we-tensile.

Kumlinganiselo kunye nokuhlolwa okungahleliwe, emva kokuba iingxaki zomgangatho zifunyenwe, ukuhlolwa okubanzi kuya kusetyenziswa ukufumanisa ukuba kukho iingxaki kuzo zonke iindawo ze-welding.
