style="text-indent:25px">如今的合金圓鋼經(jīng)過不斷的發(fā)展，在很多方面都得到了比較好的應(yīng)用，如今在進(jìn)行焊接工藝上也逐漸的得到更好的完善。合金圓鋼在進(jìn)行焊接時(shí)，先成形扁平的鋼帶，隨后使得其形狀成為圓鋼狀。一旦成形后，合金圓鋼的接縫必需被焊接到一起。這個(gè)焊縫很大水平上影響了整機(jī)的可成形性。是以，若要獲得可以或許滿意制作業(yè)內(nèi)嚴(yán)厲的測(cè)試請(qǐng)求的焊接形狀，抉擇適合的焊接技巧就極為重要。無庸置疑，鎢極氣體掩護(hù)電弧焊、高頻焊，和激光焊接曾經(jīng)在合金圓鋼的制作中各自獲得了利用。</p><p style="text-indent:25px">合金圓鋼的制造是先經(jīng)過圓鋼坯拔制成的，圓鋼變圓鋼的過程會(huì)存在不均勻的變形才產(chǎn)生棱角，同時(shí)就會(huì)產(chǎn)生應(yīng)力，其應(yīng)力的方向改變了原來的應(yīng)力平衡，所以就有了拉縮塑性變形，使厚度減小或根部起槽，造成這種現(xiàn)象的主要因素有：斷面積的分配：厚壁部分的斷面積占整個(gè)合金圓鋼斷面積的比例越大，厚壁部分承受附加拉應(yīng)力的能力越小，拉縮與起槽現(xiàn)象愈嚴(yán)重。拔制道次：在總變形量一定的條件下，增多道次，可減小每一道次的變形不均勻程度，從而減輕拉縮與起槽程度。合金圓鋼很適合工業(yè)生產(chǎn)。</p><div
