注：1、直徑不大于、E5015、E5016和E5018型焊條及直徑不大于，可適用于立焊和仰焊。2、E4322型焊條適宜單道焊。焊條型號(hào)舉例如下：例14、焊條的選用（1）結(jié)構(gòu)鋼（低碳鋼、中碳鋼、普通低合金鋼）焊條的選用采用結(jié)構(gòu)鋼制造的焊接結(jié)構(gòu)，大多要求焊縫金屬與母材等強(qiáng)度，此時(shí)可按結(jié)構(gòu)鋼的強(qiáng)度選擇相應(yīng)強(qiáng)度等級(jí)的焊條。選擇時(shí)應(yīng)注意以下兩點(diǎn)：1）鋼材的強(qiáng)度等級(jí)是按屈服點(diǎn)劃分的，而結(jié)構(gòu)鋼焊條的強(qiáng)度等級(jí)系指其抗拉強(qiáng)度的比較低保證值，兩者是不一致的。通常應(yīng)選擇抗拉強(qiáng)度保證值與母材相同或稍高的焊條。2）焊縫強(qiáng)度不是比母材高出愈多愈好，而應(yīng)等于或稍高于母材。如果焊縫強(qiáng)度過(guò)高，往往使焊縫的塑性下降，反而有害。當(dāng)焊接接頭不要求焊縫與其等強(qiáng)度時(shí)，可選用抗拉強(qiáng)度較低的焊條。（2）合金結(jié)構(gòu)鋼焊條的選用合金結(jié)構(gòu)鋼焊接時(shí)，通常均不要求焊縫金屬的合金成分與該鋼種的合金成分相同或相近，而主要考慮等強(qiáng)度。但如果母材是耐熱鋼、耐腐蝕鋼時(shí)，從保證焊接接頭的耐熱、耐腐蝕性能出發(fā)，則要求焊縫金屬的主要合金成分與母材相同或相近。此時(shí)，應(yīng)根據(jù)母材的化學(xué)成分選用焊條。（3）根據(jù)母材抗裂性要求選用焊條母材成分中，如果含C或S、P等雜質(zhì)較高時(shí)，很容易在焊縫中形成裂紋。江蘇RD12M焊絲訂購(gòu)</p><p
