<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">六大焊接工艺的焊接技巧，一文看懂。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">01</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">MIG焊接</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">01,保持1/4—3/8英寸的焊丝杆伸长（从焊枪头伸出的焊丝长度）。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">02,焊接薄板时<span style="color: black;">运用</span>小直径焊丝；焊接厚板时<span style="color: black;">运用</span>大直径焊丝和大电流焊机。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">03,<span style="color: black;">运用</span>正确的焊丝焊接工件。不锈钢焊丝焊接不锈钢、铝焊丝焊接铝、钢焊丝接钢。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">04,<span style="color: black;">运用</span>正确的<span style="color: black;">守护</span>气体。二氧化碳非常适合焊接钢材，<span style="color: black;">然则</span>用来焊接薄板则可能温度过高，应<span style="color: black;">运用</span>75%氩气和25%二氧化碳的混合气体焊接较薄的材料。焊接铝则只能<span style="color: black;">运用</span>氩气。焊接钢时，你<span style="color: black;">亦</span>可<span style="color: black;">运用</span>3种气体组合成的混合气体（氦气+氩气+二氧化碳）。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">05,要达到<span style="color: black;">掌控</span>焊道最佳的效果，应保持焊丝直接对准熔池的结合边缘。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">06,当焊接操作<span style="color: black;">处在</span>一个非正常位置的时候（立焊、横焊、仰焊），应保持较小的熔池来达到对焊道的最佳<span style="color: black;">掌控</span>，并且尽可能的<span style="color: black;">运用</span>直径最小的焊丝。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">07,<span style="color: black;">保证</span>你所<span style="color: black;">运用</span>的焊丝尺寸与套电嘴、衬管、驱动滚轮相匹配。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">08,经常清理焊枪衬管和驱动滚轮，以保持焊枪口<span style="color: black;">无</span>飞溅。<span style="color: black;">倘若</span>焊枪口堵塞<span style="color: black;">或</span>送丝不顺，则将其更换。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">09,焊接时<span style="color: black;">尽可能</span>保持焊枪笔直，以避免送丝问题。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">10,焊接操作时双手<span style="color: black;">同期</span><span style="color: black;">运用</span>以<span style="color: black;">保证</span>焊枪的稳定，且尽可能<span style="color: black;">这般</span>做。（这<span style="color: black;">一样</span>适用于焊条焊、TIG焊和等离子切割）</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">11,将送丝机的焊丝盘和驱动滚轮松紧度调节在刚好足够送丝，不要过紧。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">12,焊丝<span style="color: black;">不消</span>时，将其<span style="color: black;">保留</span>在干净和干燥的地点，避免受到污染而影响焊接效果。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">13,用直流反极性DCEP电源。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">14,拖（拉）焊枪技法能<span style="color: black;">得到</span>较深的熔透和较窄的焊缝。推枪技法则能<span style="color: black;">得到</span>较浅的熔透和较宽的焊缝。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><img src="//q4.itc.cn/q_70/images01/20240710/41df7313c84343589b4df8eb9cbf09ce.jpeg" style="width: 50%; margin-bottom: 20px;"></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">02</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">铝材焊接</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">01,最适合焊接铝材的是拉丝式焊枪，<span style="color: black;">倘若</span>你<span style="color: black;">没法</span><span style="color: black;">运用</span>这种焊枪的话，<span style="color: black;">尽可能</span><span style="color: black;">运用</span>最短的焊枪以便保持焊枪的笔直；只能<span style="color: black;">运用</span>氩气<span style="color: black;">做为</span><span style="color: black;">守护</span>气体；在焊接铝材的时候只能<span style="color: black;">运用</span>推枪手法。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">02,<span style="color: black;">倘若</span>你<span style="color: black;">发掘</span>有送丝问题，<span style="color: black;">能够</span>试一试尺寸比焊丝大一号的导电头。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">03,焊铝时最常用的焊丝是较软的标准焊丝。而另一种则要硬<span style="color: black;">有些</span>（较容易送丝），它<span style="color: black;">重点</span>用于硬度和强度<span style="color: black;">需求</span>更高的焊接操作中。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">04,在焊接<span style="color: black;">起始</span>前要做好铝材表面氧化层的清除工作，<span style="color: black;">运用</span>专用的不锈钢刷来清除氧化层。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">05,焊接结束时填充好弧坑以防止裂缝。一个办法<span style="color: black;">便是</span>在焊后将焊枪在熔池中停留数秒。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">03</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">自<span style="color: black;">守护</span>药心焊丝焊接</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">01,焊接时<span style="color: black;">运用</span>拉（或拖）枪技法。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">02,保持焊丝的清洁和干燥以达到最佳的焊接效果。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">03,这种焊接类似焊条焊，<span style="color: black;">由于</span>焊后焊缝表面的熔渣层<span style="color: black;">必要</span>在焊接完成后清理干净。清渣时<span style="color: black;">能够</span><span style="color: black;">运用</span>敲渣锤和钢丝刷。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">04,自<span style="color: black;">守护</span>药心焊丝焊不<span style="color: black;">必须</span>多余的<span style="color: black;">守护</span>气体容器。（<span style="color: black;">守护</span>药剂在焊丝里面）。这个特点使得其非常适合<span style="color: black;">运用</span>在户外作业，<span style="color: black;">由于</span>在户外<span style="color: black;">运用</span><span style="color: black;">守护</span>气体很容易被吹散。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">05,自<span style="color: black;">守护</span>药心焊丝焊在焊接薄板时要比MIG焊困难。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><img src="//q9.itc.cn/q_70/images01/20240710/7a89df00a4b041729a3564dff5dd5c0b.jpeg" style="width: 50%; margin-bottom: 20px;"></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">04</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">TIG焊</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">01,非常适合薄板焊接——干净的焊接过程<span style="color: black;">能够</span><span style="color: black;">得到</span><span style="color: black;">美丽</span>的焊接外观。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">02,焊接钢材、铝材的时候<span style="color: black;">运用</span>氩气<span style="color: black;">做为</span><span style="color: black;">守护</span>气体。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">03,<span style="color: black;">运用</span>直流正极性（DCEN）焊接钢和不锈钢，<span style="color: black;">运用</span>交流焊接铝。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">04,在TIG焊中<span style="color: black;">始终</span><span style="color: black;">运用</span>推枪技法。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">05,将钨电极的尺寸和套电嘴的尺寸相匹配。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">06,焊接铝材——应<span style="color: black;">运用</span>纯钨电极。<span style="color: black;">这般</span>能在交流焊接时，钨极易形成球状尖端。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">07,焊接钢和不锈钢——应<span style="color: black;">运用</span>含2%钍的钨电极。在直流正极焊时应把钨电极磨尖。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">05</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">焊条电弧焊</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">01,大<span style="color: black;">都数</span>时候<span style="color: black;">运用</span>拖枪技法。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">02,做好预防焊渣飞溅的准备。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">03,保持焊条的清洁和干燥—遵循制造商的<span style="color: black;">意见</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">04,熔透：负极性直流电—最大熔透，交流电—中等熔透（<span style="color: black;">亦</span>可能飞溅较多），正极性直流电—最小熔透。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">06</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">电阻焊</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">01,电阻焊不适合用来焊接铝、铜<span style="color: black;">或</span>铜合金。而只用来焊接钢和不锈钢。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">02,要得到更大热量（电流输出），应<span style="color: black;">运用</span>较短电极臂。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">03,<span style="color: black;">倘若</span>是<span style="color: black;">无</span>热量<span style="color: black;">掌控</span>功能的焊机，应利用电极臂的长度来进行<span style="color: black;">掌控</span>。例如，焊接<span style="color: black;">必须</span>低热量的薄板时采用较长的电极臂。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">04,要<span style="color: black;">重视</span>较长的电极臂可能弯曲，且你还可能失去加压在焊缝上的压力。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">05,要<span style="color: black;">保证</span>焊接工件之间<span style="color: black;">无</span>间隙，否则焊接效果会受到很大的影响。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">06,保持两个电极臂对齐，以便电极相互对准。还有，保持调节合适的压力，不要太大或太小。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">07,如果你<span style="color: black;">必须</span>工件的某一面焊后有很好的外观，你<span style="color: black;">能够</span>磨平（用<span style="color: black;">设备</span>）电极那一面。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">08,经常清洁电极，否则输出（电流）会降低。还应给电极带上合适的<span style="color: black;">守护</span>套。<a style="color: black;"><span style="color: black;">返回<span style="color: black;">外链论坛：www.fok120.com</span>，查看<span style="color: black;">更加多</span></span></a></p>
