随着化学工业的迅速发展,18-8型耐酸不锈钢(特别是1Cr18Ni9Ti)焊接任务大大增加,在焊接不锈钢时应用最普遍的是手工电弧焊。由于这种钢具有特殊的物理性能和机械性能,因此焊接操作技术与普通炭钢有明显的区别。为了广泛交流经酸,迅速掌握和提高焊接不锈钢的技术,因此我们把18-8型不锈钢的手工电弧焊接的操作技术加以总结,现叙述如下,以供广大焊接
With the rapid development of the chemical industry, 18-8 type acid-resistant stainless steel (especially 1Cr18Ni9Ti) welding tasks greatly increased, the most common application in the welding of stainless steel is manual arc welding. Due to the special physical and mechanical properties of this type of steel, there is a clear difference between welding operation techniques and ordinary carbon steels. In order to exchange acid widely, quickly grasp and improve the technology of welding stainless steel, so we 18-8 type stainless steel manual arc welding operation techniques are summarized as follows, for the majority of welding
