也可用于硬化性大的鉻鋼（如Cr5Mo、Cr9Mo、Cr13、Cr28等）以及異種鋼的焊接。A407不銹鋼焊條符合GBE310-15相當AWSE310-15說明:A407是堿***皮的Cr26Ni21純奧氏體不銹鋼焊條。熔敷金屬900~1100℃高溫條件下具有優(yōu)良的抗氧化性。采用直流反接，山東焊絲廠，可進行全位置焊接。由于焊縫為純奧氏體，山東焊絲廠，抗熱裂性能不及雙相組.織的好。用途:用于同類型的耐熱不銹鋼，不銹鋼襯里以及異種鋼的焊接，也可用來焊接硬化性大的Cr5Mo、Cr9Mo、Cr13及Cr28鋼等的焊接。A412不銹鋼焊條符合GBE310Mo-16相當AWSE310Mo-16說明:A412是鈦鈣型藥皮的Cr26Ni21Mo2純奧氏體不銹鋼焊條。由于熔敷金屬中添加了Mo，故耐蝕性、耐熱性、抗裂性能均比A402、A407有所改善。交直流兩用，操作工藝性能良好，山東焊絲廠。用途:用于焊接在高溫下工作的耐熱不銹鋼，也可用來焊接不銹鋼襯里、異種鋼等。在焊接淬硬性高的碳鋼、低合金鋼時韌性極好。A422不銹鋼焊條說明:A422是鈦鈣型藥皮的Cr25Ni18Mn8不銹鋼焊條,交直流兩用。由于焊縫中加入了較多的Mn，因而提高了焊縫的抗熱裂性能。用途:用于補焊爐卷軌機上的Cr25Ni20Si2奧氏體耐熱鋼卷筒，也可用于焊接異種鋼等。焊絲主要用于二氧化碳氣體保護焊、埋弧焊和電渣焊。山東焊絲廠</p><div

后者只預熱焊件邊緣較厚的部分。電源可采用直流正接，也可以采用交流。用交流電源焊接時，鋅的蒸發(fā)量較小。焊接參數(shù)宜采用較大的焊接電流和較快的焊接速度。厚16～20mm黃銅板的焊接參數(shù)為：焊接電流260～300A，鎢極直徑5mm，焊絲直徑～，噴嘴孔徑14～16mm，氬氣流量20～25L/min。為了減少鋅的蒸發(fā)，操作時可將填充焊絲與焊件'短接'，在填充焊絲上引弧和保持電弧，盡可能避免電弧直接作用到母材上，母材主要靠熔池金屬的傳熱來加熱熔化。焊接時，應盡可能進行單層焊，板厚小于5mm的接頭，比較好能一次焊完。焊后焊件應加熱到300～400℃進行退火處理，消除焊接應力，以防止黃銅構(gòu)件在使用時破裂。4．黃銅碳弧焊黃銅碳弧焊時，根據(jù)母材的成分選用絲221、絲222、絲224等焊絲，也可用自制的黃銅焊絲施焊。焊接可以采用氣劑301等作熔劑。焊接應短弧操作，以減少鋅的蒸發(fā)和燒損。山東焊絲廠?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。</p><div

特別對抗氯離子點蝕有好處。采用直流反接，可進行全位置焊接。用途:用于低碳的0Cr18Ni12Mo2不銹鋼設(shè)備，也可焊接焊后不進行熱處理的高鉻鋼（如Cr13、Cr17）,以及用于焊接異種鋼的焊接。A212不銹鋼焊條符合GBE318-16相當AWSE318-16說明:A212是鈦鈣型藥皮的低碳含Nb穩(wěn)定劑的Cr18Ni12Mo2Nb不銹鋼焊條。其熔敷金屬比A202、A207具有更好的抗晶間腐蝕性能。有優(yōu)良的操作工藝性能，可交直流兩用。用途:用于重要的0Cr18Ni12Mo2、00Cr17Ni14Mo2等不銹鋼的焊接，如尿素合成塔、維尼綸設(shè)備等接觸強腐蝕介質(zhì)的工件。A222不銹鋼焊條符合GBE317MoCu-16說明:A222是鈦鈣型藥皮的低碳Cr19Ni13Mo2Cu不銹鋼焊條，由于熔敷金屬含有Cu，在酸性介質(zhì)中具有比其它不銹鋼焊條更好的耐蝕性能。有優(yōu)良的焊接工藝性能，可交直流兩用。用途:用于焊接相同類型的含Cu不銹鋼設(shè)備。A232不銹鋼焊條符合GBE318V-16說明:A232是鈦鈣型藥皮的低碳Cr18Ni12Mo2V不銹鋼焊條，由于熔敷金屬含有V，故具有良好的耐熱性能和抗裂性能。有優(yōu)良的焊接工藝性能，可交直流兩用。用途:焊接一般耐熱及有一定耐蝕性的Cr19Ni10及0Cr18Ni12Mo2不銹鋼結(jié)構(gòu)。</p><p> 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度，此時可按結(jié)構(gòu)鋼的強度選擇相應強度等級的焊條。選擇時應注意以下兩點：1）鋼材的強度等級是按屈服點劃分的，而結(jié)構(gòu)鋼焊條的強度等級系指其抗拉強度的比較低保證值，兩者是不一致的。通常應選擇抗拉強度保證值與母材相同或稍高的焊條。2）焊縫強度不是比母材高出愈多愈好，而應等于或稍高于母材。如果焊縫強度過高，往往使焊縫的塑性下降，反而有害。當焊接接頭不要求焊縫與其等強度時，可選用抗拉強度較低的焊條。（2）合金結(jié)構(gòu)鋼焊條的選用合金結(jié)構(gòu)鋼焊接時，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，而主要考慮等強度。但如果母材是耐熱鋼、耐腐蝕鋼時，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，應根據(jù)母材的化學成分選用焊條。（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，很容易在焊縫中形成裂紋。鉬、鉻、碳、錳、鎳及釩等合金元素的添加，可以提高（改善）熔填金屬的強度、延性、硬度及韌性等。</p><div

要做到以下要求：一是為了保證試板坡口兩側(cè)有良好的熔合，采用的焊接電流宜稍大，當用ф，焊接電流以90A為宜；二是要采用短弧施焊，以利于保護熔池，同時利用電弧作用力把熔池鐵液托住，并且把部分熔滴過渡到試件背面（即上面）；三要使后續(xù)熔池覆蓋前一熔池的1/2，并適當提高焊接速度，以減小熔深，減小液態(tài)金屬自身重力，避免焊縫金屬下垂上凹；四是保持正確的運條方式，使焊條與試板左右兩側(cè)呈90o，并與焊接方向呈70o～80o的夾角。施焊時，焊件背面應保持2/3弧柱，以利于熔滴過渡和熔池保護。運條時應左右輕微擺動。當焊至接近試板中部時，因變形使間隙變窄，此時可不使焊條左右橫向擺動，而沿焊接方向連弧焊接；五是更換焊條接頭要迅速，應在接頭部位處于紅熱狀態(tài)下迅速引弧，盡快恢復焊接狀態(tài)，這樣可使接頭處成形良好，也可減少氣孔、夾渣等缺點。填充層的焊接填充層采用左右擺動運條方式連弧焊接，操作昱應注意兩點：一要使焊條與試板在左右方向上處于垂直狀態(tài)，以避免填充層焊縫左右不等厚，影響焊縫成形。為了把握好角度，有的焊工改用雙手握焊鉗施焊，效果不錯；二要將道間熔渣清理干凈，避免出現(xiàn)夾渣。填充層以2層為宜，較薄的焊層。自保護藥芯焊絲，是在氣保護藥芯焊絲問市不久，便被發(fā)展出來，也很快的被工業(yè)界廣為認同于特定的用途上。山東焊絲廠</p><p
