电弧焊是目前主要的焊接工艺方法之一,电焊弧光可对眼睛造成严重的伤害,是焊工遭受的最大的职业危害因素。传统焊接面罩的缺陷是导致伤害产生的主要原因之一,而新式自动变光焊接面罩的使用则可有效降低电焊弧光造成的危害。焊接是集多门类、多学科技术为一体的成形技术。它作为一种精确、可靠、低成本、高技术的材料连接方法,未来仍将是制造业的重要加工手段。其中,电弧焊仍是主要的焊接工艺方法。在发展中国家,采用手工电弧焊的方式进行焊接,仍将占焊接作业的60%左右。
Arc welding is one of the main welding methods. Arc welding can cause serious eye damage and is the biggest occupational hazard to welders. The traditional welding mask defects are one of the main causes of injury, and the use of new automatic welding mask can reduce the harm caused by welding arc. Welding is a multi-category, multi-disciplinary technology as one of the forming technology. As an accurate, reliable, low-cost and high-tech material connection method, it will remain an important manufacturing tool in the future. Among them, the arc welding is still the main method of welding process. In developing countries, welding by hand arc welding will still account for about 60% of welding operations.
