我局的日本五十铃载货汽车,近年来进厂大修时,发现发动机缸盖都出现裂纹,损坏较严重。按冷焊解放牌汽车缸体的焊修工艺,产品合格率仅不足20%,造成大量报废,直接影响了修车进度和成本。为此,我们在原冷焊解放牌汽车缸体的基础上,对五十铃汽车缸盖进行了修复攻关,经多次试验,现己形成了一种适用于五十铃汽车缸盖的焊修新工艺,提高了焊修质量,用新工艺冷焊修复缸盖的合格率达91%,这种工艺现己应用于生产,现将该工艺介绍如下:
I Board of Japan’s Isuzu truck, engine overhaul in recent years, found that the engine cylinder head cracks have occurred, the more serious damage. According to the welding welding repair process of cold welding liberation card automobile cylinder body, the passing rate of products is less than 20%, resulting in a large amount of scrapping and directly affecting the progress and cost of repairing the vehicle. To this end, we cold-welded Jiefang Dai car cylinder on the basis of the Isuzu car cylinder head repair research, after many tests, now has formed a suitable Isuzu car welding head repair process, improve The quality of welding repair, cold welding repair with new technology cylinder head pass rate of 91%, this process is now used in the production, the process is introduced as follows:
