本人对‘焊接’第6期“铜铝接头的电弧焊接”一文有若干不同看法和意见,兹提出商权。文章中某些结论是不够严密的,有些地方甚至还有错误。根据本人在铝铜焊接方面几年来工作的体会及知道的一些理论,对文章有如下的意见和看法: 1.文章中提到“碳弧焊正接时电弧稳定,可以拉长到50公厘左右,同时电弧有自动削尖的趋势”。本人认为这种说法太籠统一些。因为没有指出焊接时所用的电压。焊有色金属的特点就是高电压,强电流。从经验证
I have a number of different opinions and opinions on the article “Arc Welding of Copper and Aluminum Joints”, No. 6 of “Welding”. Some of the conclusions in the article are not strict enough, and some even have mistakes. According to my experience in the past few years in the aluminum-copper welding work and know some theory, the article has the following opinions and opinions: 1. The article mentioned “carbon arc welding is connected directly when the arc can be stretched to 50 mm , While the arc has the automatic sharpening trend. ” I think this argument is too general. Because did not point out the voltage used when welding. Non-ferrous metal welding is characterized by high voltage, high current. From verified
