成都ER100S-1泰克羅伊焊絲焊接要求焊絲突顯了許多焊接方法的有利特性，例如焊劑部分扮演了與被覆焊條能改善熔填金屬化學(xué)成分與機(jī)械性之功能。生產(chǎn)效率上又有氣體保護(hù)金屬電弧焊及埋弧焊的特點(diǎn)。
不銹鋼焊條可分為鉻不銹鋼焊條和鉻鎳不銹鋼焊條兩大類(lèi)。(1)鉻不銹鋼焊條該類(lèi)焊條主要由Crl3系列不銹鋼焊條和Crl7系列不銹鋼焊條組成。兩大系列焊條的焊接特點(diǎn)分述如下：1)Cr13系列不銹鋼焊條：如G202、G207、G217等焊條是馬氏體組織的Cr13系列不銹鋼焊條，用此系列的不銹鋼焊條焊接馬氏體不銹鋼時(shí)，焊前應(yīng)該將焊件預(yù)熱300℃以上，而且焊后還要將焊件進(jìn)行700℃的回火處理，只有采取上述工藝措施，才能避免焊縫及熱影響區(qū)因淬硬傾向較大而產(chǎn)生裂紋。2)Cr17系列不銹鋼焊條：如G302、G307等焊條是鐵素體組織的Cr17系列不銹鋼焊條，用此系列的不銹鋼焊條焊接鐵素體不銹鋼時(shí)，焊前應(yīng)該將焊件預(yù)熱200℃，而且焊后還要將焊件進(jìn)行800%的回火處理，只有采取上述工藝措施，才能避免焊縫及熱影響區(qū)475℃脆化和因淬硬傾向較大而產(chǎn)生裂紋。(2)鉻鎳不銹鋼焊條該類(lèi)焊條具有良好的耐蝕性和抗氧化性，
它被廣泛應(yīng)用于化工、化肥、石油、食品、醫(yī)療器械設(shè)備的制造。近年來(lái)，隨著我國(guó)工業(yè)的發(fā)展，鉻鎳不銹鋼焊條的品種已有三十多種，基本上滿(mǎn)足了我國(guó)建設(shè)的需要。
鉻鎳不銹鋼在焊接時(shí)，受到重復(fù)加熱，易析出炭化物，從而使耐腐蝕性和力學(xué)性能降低，因此，鉻鎳不銹鋼焊接時(shí)應(yīng)根據(jù)設(shè)備的工作條件（工作溫度及介質(zhì)種類(lèi)等）妥善選擇焊條，并在使用時(shí)注意以下事項(xiàng)：
1、銹鋼焊條的藥皮通常有鈦鈣型和低氫型兩種。其中鈦鈣型藥皮的不銹綱焊條一般由于電弧穿度淺，適宜于薄板俯焊（手工焊），不適宜全位置焊接。同時(shí)，由于不銹鋼芯電阻大，交流焊接比直流焊接容易發(fā)紅，故盡可能采用直流焊接。而低氫型藥皮的不銹鋼焊條則適宜于全位置中板以上的焊接。
2、各種不銹鋼焊條在使用時(shí)應(yīng)保持干燥，鈦鈣型藥皮應(yīng)以150~250℃烘1小時(shí)，低氫藥皮應(yīng)經(jīng)200~300℃烘1小時(shí)，（不能多次重復(fù)烘干，否則藥皮容易開(kāi)裂脫落），防止焊條藥皮粘上油污及其它臟物，以免使焊縫增加碳量和影響焊接質(zhì)量。
