黃銅焊接黃銅焊接是修鋪、加工銅材時(shí)候必不可少的加工技術(shù)。焊接，也叫作熔接、镕接，是一種常見(jiàn)的以加熱方式接合金屬或其他熱塑性材料如塑料的制造工藝及技術(shù)。下面將介紹黃銅的焊接性和黃銅焊接方法。黃銅焊接性黃銅是銅鋅合金，由于鋅的沸點(diǎn)較低，*為907℃，故焊接過(guò)程中極容易蒸發(fā)，這一點(diǎn)成為黃銅焊接的比較大問(wèn)題。在焊接高溫作用下，焊條電弧焊時(shí)鋅的蒸發(fā)量高達(dá)40%，鋅的大量蒸發(fā)，導(dǎo)致焊接接頭的力學(xué)性能和耐蝕性能下降，還使之對(duì)應(yīng)力腐蝕的敏感性增大。蒸發(fā)的鋅在空氣中立即被氧化成氧化鋅，形成白色的煙霧，給操作帶來(lái)很大困難，而且影響焊工身體健康，因此，焊接黃銅的場(chǎng)所，應(yīng)加強(qiáng)通風(fēng)等防護(hù)措施。黃銅的焊接性不良，焊接時(shí)會(huì)產(chǎn)生氣孔、裂紋、鋅的蒸發(fā)和氧化等問(wèn)題。為了解決這些問(wèn)題，在焊接時(shí)常用含硅的焊絲，因?yàn)楣柙谌鄢乇砻鏁?huì)形成一層致密的氧化硅薄膜，阻礙鋅的蒸發(fā)和氧化，并防止氫的入侵。焊后可經(jīng)470～560℃的退火處理，以消除應(yīng)力防止“自裂”現(xiàn)象。黃銅焊接的方法：氣焊、碳弧焊、焊條電弧焊和氬弧焊。1．黃銅的氣焊（1）焊絲和焊粉：焊絲采用絲221、絲224。這些焊絲中的硅、錫、鐵元素既是脫氧劑，防止焊縫產(chǎn)生氣孔，又能防止和減少鋅的蒸發(fā)和燒損。</p><p> 有利于保證焊縫的機(jī)械性能。不重要的焊縫也可用基本金屬切條作焊絲。氣體熔劑：由硼酸甲醇的混合液（沸點(diǎn)55℃）揮發(fā)而成。由乙炔帶入火焰中與氧反應(yīng)生成硼酐（B2O3）、二氧化碳和水蒸氣。硼酐凝結(jié)到基本金屬及焊絲上。焊接時(shí)產(chǎn)生強(qiáng)烈脫氧作用，與氧化物生成硼酸鹽，以鹽膜狀態(tài)浮在熔池表面，能有效地防止鋅的蒸發(fā)。氣體熔劑已成功地應(yīng)用于黃銅的焊接和堆焊上。（2）火焰性質(zhì)：預(yù)熱時(shí)采用中性火焰，以免工件表面氧化。而焊接時(shí)應(yīng)采用輕微氧化焰，這是因?yàn)檩p微氧化焰雖然燒損一部分鋅，使熔池表面形成一層氧化鋅薄膜（熔點(diǎn)1800℃），但它支能防止熔池中的鋅大量蒸發(fā)。輕微氧化焰到何種程度為宜，一般是對(duì)好中性焰后，用手稍微調(diào)一下氧氣調(diào)節(jié)閥，聽(tīng)到有“吃、吃”聲就可以了。（3）焊粉的使用方法：一般不將焊粉灑在工件上。為了節(jié)省沾焊粉時(shí)間，將焊粉倒入長(zhǎng)槽中，再把用焊炬加熱的焊絲橫放在焊粉中滾動(dòng)，使焊絲表面沾上一層焊粉（約為—1毫米厚），然后排列在傾斜的架子上，以備使用。（4）操作要點(diǎn)：焊炬上下跳動(dòng)，不作橫向擺動(dòng)。焊速較快。其它與紫銅氣焊相同。2．黃銅的焊條電弧焊焊條采用青銅芯焊條，如ECuSn-B（T227）、ECuAl-C（T237）。焊絲應(yīng)放在木托盤(pán)上，不能將其直接放在地板或緊貼墻壁。</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(dāng)用ф，焊接電流以90A為宜；二是要采用短弧施焊，以利于保護(hù)熔池，同時(shí)利用電弧作用力把熔池鐵液托住，并且把部分熔滴過(guò)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(dāng)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(yùn)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(shí)，焊件背面應(yīng)保持2/3弧柱，以利于熔滴過(guò)渡和熔池保護(hù)。運(yùn)條時(shí)應(yīng)左右輕微擺動(dòng)。當(dāng)焊至接近試板中部時(shí)，因變形使間隙變窄，此時(shí)可不使焊條左右橫向擺動(dòng)，而沿焊接方向連弧焊接；五是更換焊條接頭要迅速，應(yīng)在接頭部位處于紅熱狀態(tài)下迅速引弧，盡快恢復(fù)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(diǎn)。填充層的焊接填充層采用左右擺動(dòng)運(yùn)條方式連弧焊接，操作昱應(yīng)注意兩點(diǎn)：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(cuò)；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。江西H13焊絲</p><p
