不銹鋼的使用越來越普遍,不論生活還是生產(chǎn)中,因此對它的了解需要更深入,本文來探討不銹鋼材質(zhì)的常用焊接方法。首先,手工焊接。手工焊是一種特別普遍的、常用的,同時也是操作簡單使用方便的焊接法。電弧的長度可以依靠操作者手工來進行合理調(diào)節(jié),而調(diào)節(jié)則是根據(jù)電焊條和需要焊接的工件之間的縫隙來進行,根據(jù)縫隙的大小調(diào)節(jié)電弧的長度。焊條不僅可以作為焊接不銹鋼材質(zhì)的工具,同時,它在一定的情況下也可以作為焊縫的一種有效填充材料。而這種材料,可以更好地接合不銹鋼工件,達到更好的兼容性。其次,金屬極氣體保護焊。金屬氣體保護焊是一種自動氣體保護電弧焊。在使用此種方法的過程中,電弧在保護氣體約束下,在焊絲和不銹鋼工件之間進行燃燒焊接。機械焊接設(shè)備送入的焊絲就是一根根焊條,通過電弧下融化為液體不銹鋼。鑒于MAG焊接法的通用性和特殊性兼有的特殊性能,是當今不銹鋼焊接行業(yè)使用**為***的一種焊接法。而且,因為其具備多項優(yōu)點,在很長一段時間內(nèi)也一定是***的焊接方法。再次,鎢極惰性氣體保護焊。在這種使用方法中,電弧產(chǎn)生在穩(wěn)定的鎢電焊絲和不銹鋼材質(zhì)工件。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="湖南THW焊條訂購" src="http://tyunfile.71360.com/UploadFile/shjianmin2/637179275556074219/4349132.png"></div><p> ～HB～300適用于氮化后模具，零件表面修補。焊絲鑄造類有些合金，如鈷鉻鎢合金，不能鍛、軋和拔絲，而用鑄造方法制成。它主要用于工件表面的手工堆焊，以滿足如抗氧化、耐磨損和高溫下耐腐蝕等特殊性能要求。采用連續(xù)澆注和液態(tài)擠壓可制造出長達數(shù)米的鈷鉻鎢焊絲，用于自動填絲鎢極氣體保護電弧焊，以提高焊接效率和堆焊層質(zhì)量，同時還能改善勞動條件。鑄鐵補焊有時也采用鑄造焊絲。焊絲藥芯類用薄鋼帶卷成圓形或異形鋼管，內(nèi)填一定成分的藥粉，經(jīng)拉制成的有縫藥芯焊絲，或用鋼管填滿藥粉拉制成的無縫藥芯焊絲（見圖）。用這種焊絲焊接熔敷效率高，對鋼材適應性好，試制周期短，因而它的使用量和使用范圍不斷擴大。這種焊絲主要用于二氧化碳氣體保護焊、埋弧焊和電渣焊。藥芯焊絲中的藥粉成分一般與焊條藥皮相似。含有造渣、造氣和穩(wěn)弧成分的藥芯焊絲焊接時不需要保護氣體，稱自保護藥芯焊絲，適用于大型焊接結(jié)構(gòu)工程的施工。早在1950年代初氣保護藥芯焊絲便已開始開發(fā)問市，但至1957年才開始廣為商業(yè)上使用。此種方法可說是取自埋弧焊與CO2焊接。指實心）的優(yōu)點組合而成，焊劑包在焊絲內(nèi)并藉**CO2氣體的保護可使焊接時產(chǎn)生較柔和且穩(wěn)定的電弧以及低飛濺為其特點。</p></p><br
