150-200℃，時(shí)間1小時(shí)；烘干后放在保溫箱內(nèi)，隨用隨取。焊條外露不得超過2小時(shí)，超過2小時(shí)重新烘焙，深圳鋼橋深化設(shè)計(jì)企業(yè)，焊條烘焙次數(shù)不超過3次。焊接時(shí)間盡量選擇在白天作業(yè)，深圳鋼橋深化設(shè)計(jì)企業(yè)，深圳鋼橋深化設(shè)計(jì)企業(yè)，上午9點(diǎn)至下午4點(diǎn)之間進(jìn)行二級(jí)焊縫的焊接工作。為了保證車輛行駛安全和舒適性、避免過大的變形和振動(dòng)對(duì)鋼橋結(jié)構(gòu)產(chǎn)生不利的影響。深圳鋼橋深化設(shè)計(jì)企業(yè)</p><div
