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成分上的特點是碳高及S、P雜質高，這就增大了焊接接頭對冷卻速度變化的敏感性及冷熱裂紋的敏感性。在力學性能上的特點是強度低，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力較大的特殊性。這些因素導致焊接性不良。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)當焊縫成分與灰鑄鐵鑄件成分相同時，則在一般電弧焊情況下，由于焊縫冷卻速度遠遠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?shù)墓に嚧胧﹣頊p慢焊逢的冷卻速度。如：增大線能量，江西鐵鑄公園椅廠家。②調整焊縫化學成分來增強焊縫的石墨化能力。異質焊縫：若采用低碳鋼焊條進行焊接，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，江西鐵鑄公園椅廠家。采用異質金屬材料焊接時。石材靠背椅的表面會磨損，而且夏天受太陽直射發(fā)熱使人無法休息，江西鐵鑄公園椅廠家，石材質量大，定了位就無法移動。江西鐵鑄公園椅廠家</p><div

打理的時候也是非常的方便。公園椅設計編輯功能1.從坐姿動機來講，休閑椅要給人比較大的舒適度。2.給人比較大舒適度的腰腿之間的角度是135°，接近于躺椅。3.休閑椅的材質都是柔軟的材料，讓人身體盡量的貼合于座椅。4.休閑椅的配色都是較為舒適的色系，不會采用黑色白色等嚴肅冰冷的色彩。材料鋼木靠背椅的座椅扶手及椅腳是鋼材，而椅身并不是純木的，是合成的材料，陳本地但不堅固。不能暴曬和雨淋，會腐蝕，鋼鐵靠背椅則全部是鋼鐵制成的，造價比較高，夏天比較涼爽，但是冬天會比較冰冷，而且做時間長會對皮膚造成傷害，會腐蝕掉漆，不美觀。鋼木平凳是鋼材和木材結合是公園比較常見的座椅，這種座椅不適合長時間休息，木材容易變形。石材靠背椅的表面會磨損，而且夏天受太陽直射發(fā)熱使人無法休息，石材質量大，定了位就無法移動。鑄鐵平凳有鐵架固定的平凳，不易變形，鐵質椅子容易腐蝕，生銹，維修成本比較高。因此在設計公園椅的時候，要結合環(huán)境、人群等特定條件，為人們帶來了便利，使環(huán)境更加和諧。江西鐵鑄公園椅生產(chǎn)商公園椅廠家，是研發(fā)、生產(chǎn)、銷售園林椅的企業(yè)廠家，我們統(tǒng)稱為園林椅廠家。</p><div
