(三)硬质合金刀片的焊接在本刊第八期上,我们已经谈过了硬质合金的性质和选择方法,以及正确使用硬质合金的方法,现在就谈一谈硬质合金刀片的焊接。硬质合金刀片的焊接质量是很重要的,如果焊接得不好,就会使刀片出现裂纹和断裂,甚至使刀片脱落,影响刀具的使用寿命和劳动生产率。下面就是防止产生这些缺点的方法。1.焊接前的准备工作:在焊接硬质合金刀片前,先要把刀片检查一下,有缺陷的刀片不能使用。如果刀片的底面不平,要用绿色碳
(C) the cemented carbide blade welding In the issue of the eighth issue, we have already talked about the nature of the cemented carbide and the selection method, as well as the proper use of cemented carbide method, and now to talk about the carbide blade welding. The quality of the carbide inserts is very important. If the welding is not done well, the inserts will crack and break, and the inserts may even fall off, affecting the tool life and labor productivity. Here’s how to prevent these shortcomings. 1. Preparation before welding: Prior to welding carbide inserts, first check the blade, defective blades can not be used. If the underside of the blade is uneven, use green carbon
