style="text-indent:25px">熔是在焊接過(guò)程中將工件接口加熱至熔化狀態(tài)，不加壓力完成焊接的方法。熔焊時(shí)，熱源將待焊兩工件接口處迅速加熱熔化，形成熔池。熔池隨熱源向前移動(dòng)，冷卻后形成連續(xù)焊縫而將兩工件連接成為一體。壓焊是在加壓條件下，使兩工件在固態(tài)下實(shí)現(xiàn)原子間結(jié)合，又稱(chēng)固態(tài)焊接。常用的壓焊工藝是電阻對(duì)焊，當(dāng)電流通過(guò)兩工件的連接端時(shí)，該處因電阻很大而溫度上升，當(dāng)加熱至塑性狀態(tài)時(shí)，在軸向壓力作用下連接成為一體。釬焊是使用比工件熔點(diǎn)低的金屬材料作釬料，將工件和釬料加熱到高于釬料熔點(diǎn)、低于工件熔點(diǎn)的溫度，利用液態(tài)釬料潤(rùn)濕工件，填充接口間隙并與工件實(shí)現(xiàn)原子間的相互擴(kuò)散，從而實(shí)現(xiàn)焊接的方法。常州焊接公司哪家好焊接電子元件，一般采用有松香芯的焊錫絲。</p><div

style="text-indent:25px">焊接，可以產(chǎn)生豐富的藝術(shù)創(chuàng)作的表現(xiàn)語(yǔ)言。焊接通常是在高溫下進(jìn)行的，而金屬在高溫下，會(huì)產(chǎn)生許多美妙豐富的變化。金屬母材會(huì)發(fā)生顏色變化和熱變形（即焊接熱影響區(qū)) ；焊絲熔化后會(huì)形成一些漂亮的肌理；而焊接缺陷在焊接藝術(shù)中更是經(jīng)常被應(yīng)用。焊接缺陷是指焊接過(guò)程中，在焊接接頭產(chǎn)生的不符合設(shè)計(jì)或工藝要求的缺陷。其表現(xiàn)形式主要有焊接裂紋、氣孔、咬邊、未焊透、未熔合、夾渣、焊瘤、塌陷、凹坑、燒穿、夾雜等這是個(gè)十分有趣的現(xiàn)象：在現(xiàn)在的金屬藝術(shù)創(chuàng)作中，焊接的藝術(shù)性通常體現(xiàn)在一些工業(yè)焊接的失敗操作之中，或者說(shuō)蘊(yùn)藏于一些工業(yè)焊接極力避免的焊接缺陷之中。其次，焊接藝術(shù)語(yǔ)言是獨(dú)特的。一件焊接雕塑，粗的焊縫裸露在雕塑表面，各種不規(guī)則的切割痕跡也變成了藝術(shù)家優(yōu)美的藝術(shù)語(yǔ)言在很多情況下，由于焊接雕塑所追求的粗糙質(zhì)樸的風(fēng)格，金屬的銹蝕、瑕疵也大多根據(jù)作品的需要特意保留，因此，在焊接雕塑中常常可以感覺(jué)到一種非雕琢的、原始的美。</p><p style="text-indent:25px">焊接變形產(chǎn)生的原因分析。鋼結(jié)構(gòu)剛度：剛度是指結(jié)構(gòu)體對(duì)拉伸方向和彎曲變形的抵抗能力。鋼結(jié)構(gòu)的剛度主要取決于結(jié)構(gòu)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(dāng)鋼結(jié)構(gòu)剛度不足時(shí)，在設(shè)計(jì)焊接連接縫位置和數(shù)量時(shí)，應(yīng)在結(jié)構(gòu)體對(duì)稱(chēng)安排，且焊接順序是合理的，構(gòu)件只能產(chǎn)生線(xiàn)性變形;當(dāng)焊縫為不對(duì)稱(chēng)的安排，產(chǎn)生的多為彎曲變形。焊接前應(yīng)對(duì)元件引腳或電路板的焊接部位進(jìn)行焊前處理。</p><div

style="text-indent:25px">吸錫器拆焊法這種方法是利用吸錫器的內(nèi)置空腔的負(fù)壓作用，將加熱后熔融的焊錫吸人空腔，使引線(xiàn)與焊盤(pán)分離。吸錫繩拆焊法是利用吸錫繩吸走熔融的焊錫而使引線(xiàn)與焊盤(pán)分離的方法。將編織線(xiàn)的部分涂上松香助焊劑，然后放在將要拆焊的焊點(diǎn)上，再把電烙鐵放在編織線(xiàn)上加熱焊點(diǎn)，待焊點(diǎn)焊錫熔化后，就被銅編織線(xiàn)吸去。當(dāng)編織繩吸滿(mǎn)錫后，就不能再使用，需將吸滿(mǎn)焊料的地方剪去。空頭針拆焊法該法是利用尺寸相當(dāng)（孔徑稍大于引線(xiàn)直徑）的空針頭（也可用注射器針頭），套在需要拆焊的引線(xiàn)上，當(dāng)電烙鐵加熱焊錫熔化的同時(shí)，迅速旋轉(zhuǎn)針頭直到烙鐵撤離焊錫凝固后方可停止，這時(shí)拔出針頭，引線(xiàn)已被分離。吸錫電烙鐵是一種**拆焊電烙鐵，它能在對(duì)焊點(diǎn)加熱的同時(shí)，把錫吸人內(nèi)腔，從而完成拆焊。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(xué)冶金反應(yīng)所引起的焊接性變化。常州焊接公司哪家好</p><p
