摘要：<div><a href="http://www.it147.com">不鏽鋼</a>的縫焊焊接工藝參數(shù)</div> <div>縫焊構(gòu)造用的*多的不鏽鋼是奧氏體不鏽鋼，他的焊接性很好，但因?yàn)樗碾妼?dǎo)率和熱導(dǎo)率均較低，故縫焊時(shí)易用小的焊接電流和短的焊接工夫。其高溫強(qiáng)度高，須采用較大的電極壓力和中等的焊接速度。因?yàn)樗木€膨脹係數(shù)比低碳鋼大，必需留意避免焊接變形。為了防止因?yàn)檫^熱惹起碳鉻化合物析出，宜采用偏硬的焊接前提焊接，還增強(qiáng)外部水冷電極。 下表為奧氏體不鏽鋼縫焊的焊接工藝參數(shù)。</div> <div>奧氏體不鏽鋼縫焊工藝參數(shù)（HB/Z78-1984）</div> <table border="1" cellspacing="0" cellpadding="0"> <tbody> <tr> <td width="81"> <div>焊件厚度mm</div> </td> <td width="81"> <div>焊輪寬度mm</div> </td> <td width="81"> <div>焊接時(shí)間s</div> </td> <td width="81"> <div>間隔時(shí)間s</div> </td> <td width="81"> <div>焊接電流A</div> </td> <td width="81"> <div>電極力N</div> </td> <td width="81"> <div>焊接速度m/min</div> </td> </tr> <tr> <td width="81"> <div>0.3+0.3</div> </td> <td width="81"> <div>3.0-3.5</div> </td> <td width="81"> <div>0.02-0.04</div> </td> <td width="81"> <div>0.02-0.04</div> </td> <td width="81"> <div>4.5-5.5</div> </td> <td width="81"> <div>2500-3000</div> </td> <td width="81"> <div>1.0-1.5</div> </td> </tr> <tr> <td width="81"> <div>0.5+0.5</div> </td> <td width="81"> <div>4.5-5.5</div> </td> <td width="81"> <div>0.02-0.06</div> </td> <td width="81"> <div>0.04-0.06</div> </td> <td width="81"> <div>6.0-7.0</div> </td> <td width="81"> <div>3400-3800</div> </td> <td width="81"> <div>0.8-1.2</div> </td> </tr> <tr> <td width="81"> <div>0.8+0.8</div> </td> <td width="81"> <div>5.0-6.0</div> </td> <td width="81"> <div>0.04-0.10</div> </td> <td width="81"> <div>0.06-0.08</div> </td> <td width="81"> <div>7.0-8.0</div> </td> <td width="81"> <div>4000-5000</div> </td> <td width="81"> <div>0.6-0.8</div> </td> </tr> <tr> <td width="81"> <div>1.0+1.0</div> </td> <td width="81"> <div>5.5-6.5</div> </td> <td width="81"> <div>0.08-0.10</div> </td> <td width="81"> <div>0.06-0.08</div> </td> <td width="81"> <div>8.0-9.0</div> </td> <td width="81"> <div>5000-6000</div> </td> <td width="81"> <div>0.6-0.7</div> </td> </tr> <tr> <td width="81"> <div>1.2+1.2</div> </td> <td width="81"> <div>6.5-7.5</div> </td> <td width="81"> <div>0.08-0.12</div> </td> <td width="81"> <div>0.06-0.10</div> </td> <td width="81"> <div>8.5-10</div> </td> <td width="81"> <div>5500-6200</div> </td> <td width="81"> <div>0.5-0.6</div> </td> </tr> <tr> <td width="81"> <div>1.5+1.5</div> </td> <td width="81"> <div>7.0-8.0</div> </td> <td width="81"> <div>0.10-0.14</div> </td> <td width="81"> <div>0.10-0.14</div> </td> <td width="81"> <div>9.0-12</div> </td> <td width="81"> <div>6000-7000</div> </td> <td width="81"> <div>0.4-0.6</div> </td> </tr> <tr> <td width="81"> <div>2.0+2.0</div> </td> <td width="81"> <div>7.5-8.5</div> </td> <td width="81"> <div>0.14-0.196</div> </td> <td width="81"> <div>0.12-0.18</div> </td> <td width="81"> <div>10-13</div> </td> <td width="81"> <div>7000-8000</div> </td> <td width="81"> <div>0.4-0.5</div> </td> </tr> </tbody> </table> <div><span style="color: #993300">-公司至成立以來，以&ldquo;誠(chéng)信、合作、雙贏、發(fā)展&rdquo;為經(jīng)營(yíng)宗旨，堅(jiān)持&ldquo;價(jià)格**、用戶、信譽(yù)&rdquo;的營(yíng)銷理念，在市場(chǎng)上獲得了良好的口碑。<br /> &nbsp;&nbsp; 029&mdash;88633755<br /> </span>詳情參考：<a href="http://www.it147.com">http://www.it147.com</a></div> <div>&nbsp;</div> <div>&nbsp;</div>
