前言在現代的工業中,合金鋼被廣泛地应用着,但是合金鋼的焊接还存在着某些困难。用作合金鋼焊接和堆焊用的合金鋼焊条的铁芯,通常是由鑄造和冷拉製成。但是由於合金鋼本身固有的特性(高的机械性能),要鑄造和冷拉小直徑的合金鋼铁芯是很困难的;因此合金鋼铁芯的缺乏就直接影响了合金鋼焊接与堆焊的廣泛应用。管狀粉末焊条順利地解决了各种合金鋼铁芯缺乏的困难,因此它給合金鋼的堆焊与焊接開拓了廣阔的道路。一、什麼是管狀粉末焊条管狀粉末焊条与一般的普通焊条有着根本的不同,它的制造原理主要是根据粉末冶炼的道理。具
Introduction In the modern industry, alloy steel is widely used, but the alloy steel welding there are still some difficulties. The core of alloy steel electrodes used for welding and surfacing alloy steel is usually made by casting and cold drawing. However, due to the inherent properties of the alloy steel (high mechanical properties), it is very difficult to cast and cold-draw small diameter alloy steel core; therefore, the lack of alloy steel core directly affects the welding and surfacing of the alloy steel widely used. Tubular powder electrode successfully solve the lack of various alloy steel core difficulties, so it gives the alloy steel surfacing and welding open up a vast road. First, what is the tubular powder electrode Ordinary electrode with ordinary powder electrode is fundamentally different, its manufacturing principle is based on the principle of powder smelting. With
