不锈钢的缝焊焊接工艺参数

摘要：<div><a href="http://www.camrosegroup.com">不锈钢</a>的缝焊焊接工艺参数</div> <div>缝焊构造用的*多的不锈钢是奥氏体不锈钢，他的焊接性很好，但因为它的电导率和热导率均较低，故缝焊时易用小的焊接电流和短的焊接工夫。其高温强度高，须采用较大的电极压力和中等的焊接速度。因为它的线膨胀系数比低碳钢大，必需留意避免焊接变形。为了防止因为过热惹起碳铬化合物析出，宜采用偏硬的焊接前提焊接，还增强外部水冷电极。 下表为奥氏体不锈钢缝焊的焊接工艺参数。</div> <div>奥氏体不锈钢缝焊工艺参数（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>焊轮宽度mm</div> </td> <td width="81"> <div>焊接时间s</div> </td> <td width="81"> <div>间隔时间s</div> </td> <td width="81"> <div>焊接电流A</div> </td> <td width="81"> <div>电极力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">-公司至成立以来，以&ldquo;诚信、合作、双赢、发展&rdquo;为经营宗旨，坚持&ldquo;价格**、用户、信誉&rdquo;的营销理念，在市场上获得了良好的口碑。<br /> &nbsp;&nbsp; 029&mdash;88633755<br /> </span>详情参考：<a href="http://www.camrosegroup.com">http://www.camrosegroup.com</a></div> <div>&nbsp;</div> <div>&nbsp;</div>
