NBC型CO_2气体保护半自动弧焊机的送丝软管和水冷焊枪部分,在生产使用中极易损坏,且该送丝软管自制困难,购买价格又很高,因此,影响了CO_2焊接工艺方法的推广应用。后来,我厂采用高压胶管代替CO_2焊机的送丝软管(适用于ф1.6毫米焊丝),经生产试用证明,使用效果较好,成本仅为原送丝软管的1/5。下面将改进后的送丝软管结构及使用性能介绍如下。一、送丝软管的结构原CO_2焊机的送丝软管是用内芯为ф1.2毫米的弹簧钢丝,绕
NBC type CO_2 gas shielded semi-automatic arc welding machine hose and water-cooled welding torch part of the easy to damage during production and use, and the wire hose difficult to make, the purchase price is very high, thus affecting the CO_2 welding process The promotion and application. Later, I use high-pressure hose instead of CO_2 welding machine wire feeding hose (for ф1.6 mm wire), the trial proved by production, the use of better, the cost is only the original wire feeding hose 1/5. The following will be improved wire feeding hose structure and performance are described below. First, the structure of the wire feeding tube The original CO_2 welding wire feeding hose is the inner core of ф1.2 mm spring wire, around
