為什么有消費(fèi)者反饋自己購買的桁架不耐用,關(guān)系產(chǎn)品質(zhì)量好壞的因素?zé)o外乎這兩點(diǎn),一是原材料,二是生產(chǎn)工藝,桁架生產(chǎn)焊接工藝占據(jù)著舉足輕重的作用。焊接要把握溫度和焊縫所處的位置。那么在購買桁架時(shí),你可以從哪些地方來判斷焊接工藝的好壞。
首先,觀察焊接點(diǎn)是否均勻,流暢。桁架上如果有一些金屬疙瘩,那很可能是因?yàn)楹附又袨榘盐蘸眠m宜溫度,溫度過高因此導(dǎo)致一端出現(xiàn)液化反應(yīng),因此出現(xiàn)變形。
其次,注意觀察焊接縫位置。每一個(gè)桁架成型前都可謂經(jīng)歷了千錘百煉,每一次焊接留下的焊縫除了分布在節(jié)點(diǎn)處,還會(huì)在其他地方,比如底部焊接的中部,為了達(dá)到受力均勻,桁架也容易變形。
