不銹鋼焊材焊接方法

       手(shou)(shou)工焊(han)是(shi)一種(zhong)非常普遍(bian)的(de)(de)、易于(yu)使(shi)用(yong)的(de)(de)焊(han)接(jie)(jie)方法.電(dian)(dian)(dian)(dian)弧(hu)的(de)(de)長度(du)(du)靠人的(de)(de)手(shou)(shou)進行(xing)調節(jie)，它決定(ding)于(yu)電(dian)(dian)(dian)(dian)焊(han)條(tiao)(tiao)和工件之間縫(feng)隙(xi)的(de)(de)大小。同(tong)時，當(dang)作為(wei)電(dian)(dian)(dian)(dian)弧(hu)載體(ti)時，電(dian)(dian)(dian)(dian)焊(han)條(tiao)(tiao)也(ye)是(shi)焊(han)縫(feng)填充材料.這種(zhong)焊(han)接(jie)(jie)方法很簡單，可以用(yong)來(lai)焊(han)接(jie)(jie)幾乎所有材料。對(dui)于(yu)室外使(shi)用(yong)，它有很好的(de)(de)適應性，即使(shi)在水下(xia)使(shi)用(yong)也(ye)沒問題.大多(duo)(duo)數電(dian)(dian)(dian)(dian)焊(han)機可以TIG焊(han)接(jie)(jie).在電(dian)(dian)(dian)(dian)極(ji)焊(han)中(zhong)，電(dian)(dian)(dian)(dian)弧(hu)長度(du)(du)決定(ding)于(yu)人的(de)(de)手(shou)(shou)：當(dang)你改(gai)變電(dian)(dian)(dian)(dian)極(ji)與(yu)工件的(de)(de)縫(feng)隙(xi)時，你也(ye)改(gai)變了(le)電(dian)(dian)(dian)(dian)弧(hu)的(de)(de)長度(du)(du).在大多(duo)(duo)數情況下(xia)，焊(han)接(jie)(jie)采用(yong)直流(liu)電(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)極(ji)既作為(wei)電(dian)(dian)(dian)(dian)弧(hu)載體(ti)，同(tong)時也(ye)作為(wei)焊(han)縫(feng)填充材料。
       電(dian)極由合金(jin)或非合金(jin)金(jin)屬芯絲和(he)焊(han)(han)條(tiao)(tiao)藥皮(pi)(pi)組成。這(zhe)層藥皮(pi)(pi)保(bao)護焊(han)(han)縫(feng)不(bu)受(shou)空氣的(de)侵害，同時穩(wen)定電(dian)弧.它還引起渣層的(de)形成，保(bao)護焊(han)(han)縫(feng)使(shi)它成型(xing).電(dian)焊(han)(han)條(tiao)(tiao)即可(ke)是鈦型(xing)焊(han)(han)條(tiao)(tiao)，也可(ke)是緘性的(de)，這(zhe)決定于藥皮(pi)(pi)的(de)厚度和(he)成分(fen)。鈦型(xing)焊(han)(han)條(tiao)(tiao)易(yi)于焊(han)(han)接，焊(han)(han)縫(feng)扁(bian)平(ping)美觀.此外，焊(han)(han)渣易(yi)于去除.如果(guo)焊(han)(han)條(tiao)(tiao)貯存時間(jian)長，必(bi)須重新烘烤.因為來自空氣的(de)潮氣會(hui)很快在(zai)焊(han)(han)條(tiao)(tiao)中(zhong)積聚(ju)。
