我厂以修理汽车为主,但因缺少排气门配件,有时影响汽车出厂。经几位师傅研究,用汽焊法在气门密封面上堆焊不锈钢,取得良好效果。堆焊前,应将气门上的油脂及脏物清除,直至出现金属光泽为止,然后把气门放在一个一头高一头低的小架上,使气门的密封面堆焊处保持水平。堆焊工具采用小型焊枪 I plant mainly to repair the car, but due to lack of exhaust valve parts, and sometimes affect the car factory. After several master studies, with welding method in the valve sealing surface welding stainless steel, and achieved good results. Before welding, the grease and dirt on the valve should be removed until a metallic luster appears, then the valve is placed on a small frame with a lower head and a lower head to keep the sealing surface of the valve at the level of welding.
