Cov Khoom Siv Yuav Tsum Tau: Ib txheej ntawm phau ntawv siv hluav taws xob vuam khoom, ib lub tes tuav lub kaum ntse ntse, ib lub tshuab hluav taws xob cua rauj, thiab ib tus kav ca.
Ua ntej-welding Preparation:
1. Tshawb xyuas thiab ntsuas cov khoom siv kom paub tseeb tias nws ua haujlwm li qub;
2. Npaj φ4.0J402 vuam rods, nyiam dua qhuav ntawm 300℃-350℃rau ib teev.
Vuam txheej txheem:
1. Sib dhos: Sib dhos lub khob hliav qab thiab flange loj raws li cov duab kos, ces faib cov flange loj rau hauv 8 qhov sib npaug.
2. Vuam: Vim lub thickness ntawm lub flange thiab lub bevel loj, segmented symmetrical, multi- txheej vuam yog saws.
Weld Quality:
Lub zog weld yuav tsum tsawg kawg mus txog lub zog ntawm cov khoom siv hauv paus. Weld nto yuav tsum du thiab tsis muaj teeb meem xws li hlawv-los ntawm, porosity, weld leaks, slag inclusions, undercut, thiab tsis tiav vuam. Qhov siab qhov siab yuav tsum tsawg dua 2 hli.
