style="text-indent:25px">因為高頻焊H型鋼在市場上有著很好的口碑，所以許多修建單位甘心運用它，像一般的大型工地往往運用許多的高頻焊H型鋼，雖然高頻焊H型鋼的質(zhì)量很好，但假定工作人員不合理進行運用的話，它也是會出現(xiàn)安全質(zhì)量問題的，所以咱們在運用高頻焊H型鋼時，應留神一些問題。H型鋼在建材構件有時候厚度或者是寬度是不一樣的，這時就需要在對接時做到精確的控制，留神板材的厚度是否在容許的過失規(guī)劃之內(nèi)，做到平穩(wěn)的過度。就是構件在貯存的時分，或許會有潮式的狀況的存在，或者是在經(jīng)受過下雨，下雪的氣候之后，因而在進行焊接之前要保證焊接金屬構件的單調(diào)，做到不影響焊接質(zhì)量。</p><p
