第二節(jié)鑄鐵焊接性分析一、灰鑄鐵焊接性分析灰鑄鐵在化學(xué)成分上的特點(diǎn)是碳高及S、P雜質(zhì)高，這就增大了焊接接頭對(duì)冷卻速度變化的敏感性及冷熱裂紋的敏感性。在力學(xué)性能上的特點(diǎn)是強(qiáng)度低，基本無塑性。焊接過程具有冷速快及焊件受熱不均勻而形成焊接應(yīng)力較大的特殊性。這些因素導(dǎo)致焊接性不良。主要問題兩方面：一方面是焊接接頭易出現(xiàn)白口及淬硬組.織。另一方面焊接接頭易出現(xiàn)裂紋。(一)焊接接頭易出現(xiàn)白口及淬硬組.織以含碳為3%，含硅，分析電弧焊焊后在焊接接頭上組.織變化的規(guī)律。1.焊縫區(qū)當(dāng)焊縫成分與灰鑄鐵鑄件成分相同時(shí)，則在一般電弧焊情況下，由于焊縫冷卻速度遠(yuǎn)遠(yuǎn)大于鑄件在砂型中的冷卻速度，焊縫主要為共晶滲碳體+二次滲碳鐵+珠光體，即焊縫基本為白口鑄鐵組.織。防止措施：焊縫為鑄鐵①采用適當(dāng)?shù)墓に嚧胧﹣頊p慢焊逢的冷卻速度。如：增大線能量。②調(diào)整焊縫化學(xué)成分來增強(qiáng)焊縫的石墨化能力。異質(zhì)焊縫：若采用低碳鋼焊條進(jìn)行焊接，常用鑄鐵含碳為3%左右，就是采用較小焊接電流，母材在***層焊縫中所占百分比也將為1／3～1／4，其焊縫平均含碳量將為～（C＞）。這種高碳鋼焊縫在快冷卻后將出現(xiàn)很多脆硬的馬氏體。采用異質(zhì)金屬材料焊接時(shí)。</p><p>

有的被弄得很臟，誰都不想坐；有的被專心粉碎，底子不克不及坐；大都環(huán)境下，這些座椅沒人保護(hù)，***都成為安排，乃至影響市容。我市新增戶外休閑椅，一方面，表現(xiàn)出當(dāng)局以報(bào)酬本，為廣大年夜市平易近乘涼和活動(dòng)供給了便當(dāng)，加強(qiáng)了市平易近幸福感；另外一方面，經(jīng)由過程改良環(huán)境，打造宜居城市，可讓更多人喜好這座城市。作為市平易近，每小我都要愛護(hù)保重和愛護(hù)保重這些公共設(shè)施，不克不及亂涂亂畫將其弄臟，更不克不及隨便破壞。可以想象，城市里的公共設(shè)施要么臟兮兮的令人惡心，要么支離破裂慘不忍睹，市平易近的本質(zhì)必定不會(huì)很高。這些休閑椅若是得不到愛護(hù)保重，沒人愿坐，沒人敢坐，成為安排，那么，我們真的有需要當(dāng)真核閱如許的現(xiàn)象，并力求有所改進(jìn)。但愿新增的這批休閑座椅能獲得市平易近庇護(hù)；但愿這批戶外休閑椅，能“承受”得住文明本質(zhì)的“重量”。公園椅不僅為人們帶來了便利，還使環(huán)境更加和諧。福建休閑座椅直銷</p><p
