style="text-indent:25px">焊接質量好；焊接生產率高；無脫氧去氫反應（易形成焊接缺陷，對焊接材料表面清理要求特別嚴格）；抗風能力差；焊接設備復雜。應用幾乎能焊所有的金屬材料，主要用于有色金屬及其合金，不銹鋼及某些合金鋼的焊接。薄厚度約為1毫米，大厚度基本不受限制。TIG焊原理在惰性氣體保護下，利用鎢極與焊件間產生的電弧熱熔化母材和填充焊絲（也可不加填充焊絲），形成焊縫的焊接方法。焊接過程中電極不熔化。主要特點適應能力強（電弧穩(wěn)定，不會產生飛濺）；焊接生產率低（鎢極承載電流能力較差（防鎢極熔化和蒸發(fā)，防焊縫夾鎢））；生產成本較高。應用可焊所有金屬材料，常用于不銹鋼，高溫合金，鋁、鎂、鈦及其合金，難熔活潑金屬（鋯、鉭、鉬、鈮等）和異鐘金屬的焊接。焊接厚度一般在6毫米以下的焊件，或厚件的打底焊。利用小角度坡口可以實現(xiàn)90mm以上厚度的窄間隙TIG自動焊</p><p style="text-indent:25px">焊接變形產生的原因分析。鋼結構剛度：剛度是指結構體對拉伸方向和彎曲變形的抵抗能力。鋼結構的剛度主要取決于結構截面形狀和尺寸的大小。例如，工字鋼截面和縱向桁架變形量，主要取決于其橫截面面積的弦桿截面大小的部分。再如，工字型、丁字型或其他形狀的型鋼的彎曲變形量主要取決于截面的抗彎剛度。焊接連接縫位置和數(shù)量：當鋼結構剛度不足時，在設計焊接連接縫位置和數(shù)量時，應在結構體對稱安排，且焊接順序是合理的，構件只能產生線性變形;當焊縫為不對稱的安排，產生的多為彎曲變形。焊絲和焊劑是埋弧焊的消耗材料。</p><div

style="text-indent:25px">冶金焊接性是指熔焊高溫下的熔池金屬與氣相、熔渣等相之間發(fā)生化學冶金反應所引起的焊接性變化。這些冶金過程包括：合金元素的氧化、還原、蒸發(fā)，從而影響焊縫的化學成分和組織性能；氧、氫、氮等的溶解、析出對生成氣孔或對焊縫性能的影響；在焊縫結晶及冷卻過程中，由于焊接熔池的化學成分、凝固結晶條件以及接頭區(qū)熱脹冷縮和拘束應力等影響，有時產生熱裂紋或冷裂紋。除材料本身化學成分和組織性能的影響之外，焊接材料、焊接方法、工藝參數(shù)、保護氣體等對冶金焊接性有重要的影響。除了在研制新材料時可以改善冶金焊接性之外，還可以通過選擇新焊接材料、新焊接工藝等途徑來改善冶金焊接性。焊接熱影響區(qū)的脆化常常是引起焊接接頭開裂和脆性破壞的主要原因。揚州焊接</p><p

style="text-indent:25px">焊絲和焊劑是埋弧焊的消耗材料，從碳素鋼到高鎳合金多種金屬材料的焊接都可以選用焊絲和焊劑配合進行埋弧焊接.。埋弧焊焊絲的選用既要考慮焊劑成分的影響，又要考慮母材的影響。為了得到不同的焊縫成分和力學性能，可以采用一種焊劑（主要是熔煉焊劑）與幾種焊絲配合，也可以采用一種焊絲與幾種焊劑（主要是燒結焊劑）配合。低碳鋼和低合金鋼埋弧焊常用焊絲有如下三類：低錳焊絲常配合高錳焊劑用于低碳鋼用強度較低的低合金鋼焊接。中錳焊絲主要用于低合金鋼焊接，也可配合低錳焊劑用于低碳鋼焊接。高錳焊絲用于低合金鋼焊接。揚州焊接</p></p><br
