YT30硬质合金刀具氧乙炔焊,在镶焊工艺上存在一些问题,如果操作不当,则往往会造成刀片断裂。这不仅降低使用寿命,而且也影响了产品质量。本文就如何选择YT30硬质合金刀具的焊接工艺,提高其性能和质量的问题作一介绍。焊接试验之前,对YT30合金刀具的物理性能作了分析。镶焊时,YT30刀具膨胀系数≤1/2钢的膨胀系数。因此,在镶焊硬质合金时,刀片、焊料、刀杆之间会产生很大的应力,且不易掌握。
YT30 carbide cutting tools oxyacetylene welding, welding process in the presence of some problems, if not properly handled, it will often result in blade fracture. This not only reduces the service life, but also affects the product quality. This article on how to choose YT30 carbide cutting tool welding process, improve its performance and quality of the problem to make an introduction. Prior to the welding test, the physical properties of the YT30 alloy tool were analyzed. In welding, YT30 tool expansion coefficient ≤ 1/2 of the expansion coefficient of steel. Therefore, in the welding of cemented carbide, the blade, solder, arbor will have a lot of stress, and not easy to grasp.
