焊接生產(chǎn)中大量采用焊條電弧焊。在工業(yè)發(fā)達(dá)國家，焊條的產(chǎn)量仍占焊材總產(chǎn)量的30%左右。在我國，這一比例為80%~90%左右。但從世界焊材發(fā)展的總趨勢(shì)看，隨著氣體保護(hù)焊工藝的***應(yīng)用和藥芯焊絲不斷崛起，手工焊條總的需求量會(huì)逐年下滑，今后的主要應(yīng)用對(duì)象是修配及某些特殊場(chǎng)合。在焊絲的生產(chǎn)上，埋弧焊焊絲在我國已經(jīng)應(yīng)用得非常***，埋弧焊用薄鋼帶也有應(yīng)用。近年來氣體保護(hù)焊和藥芯焊絲的應(yīng)用得到很大發(fā)展，使焊絲在消耗焊材中所占的比例日益增加，成為一種重要的焊接材料。焊絲的分類焊絲按其結(jié)構(gòu)可分為實(shí)芯焊絲和藥芯焊絲。實(shí)芯焊絲多為冷拔鋼絲；而藥芯焊絲則是由薄鋼帶縱向折迭并加入藥粉后，再行拉拔而成。實(shí)芯焊絲使用的歷史比較長(zhǎng)，為目前主要使用的焊絲；藥絲焊絲的使用比起實(shí)芯焊絲來晚了許多，但由于其具有一系列優(yōu)點(diǎn)，在生產(chǎn)中應(yīng)用得越來越多。焊接用的焊絲按其保護(hù)方式又可分為兩大類：一類是焊接時(shí)焊絲只起填充金屬和導(dǎo)電的作用，施焊過程中要依靠焊劑保護(hù)或氣體保護(hù)，如埋弧焊、CO2氣體保護(hù)焊中使用的實(shí)芯焊絲和CO2氣體保護(hù)焊中使用的部分藥芯焊絲；另一類焊絲在焊接過程中不需要外加氣體或焊劑的保護(hù)。安徽鑄鐵焊條焊絲廠家電弧穩(wěn)定劑鈉及鉀可以使電弧保持柔和順暢而且降低飛濺。</p><div
