1.怎(zen)么(me)使用(yong)陶瓷(ci)焊接襯墊？

把襯(chen)墊(dian)放在鋼(gang)板和工件所規定的形(xing)狀和尺寸的坡口背面，從正面焊，既能(neng)雙面一次成(cheng)形(xing)，背面焊縫成(cheng)型(xing)飽滿(man)，焊接襯(chen)片批發，焊跡整齊。

2.陶瓷焊(han)接(jie)襯墊應(ying)用在(zai)哪些領(ling)域(yu)？

陶瓷焊(han)接襯(chen)墊(dian)廣泛應用于(yu)船舶建(jian)造(zao)、鋼結構(gou)、橋梁、建(jian)筑、管道工(gong)程、壓力容器、化工(gong)機(ji)械、冶金(jin)機(ji)械制造(zao)中。

3.使(shi)用時需要注意什(shen)么？

一(yi)(yi)般襯墊中(zhong)間都會有(you)一(yi)(yi)條紅色(se)的(de)對準(zhun)線（不包括圓柱那種(zhong)），貼的(de)時候對應板(ban)縫中(zhong)間。還有(you)一(yi)(yi)點(dian)很正要(yao)，貼襯墊的(de)時候一(yi)(yi)定要(yao)把鐵板(ban)表面的(de)灰塵(chen)清理(li)干凈，要(yao)不會貼不緊，焊接的(de)時候容易脫落。

當(dang)需要采用熔(rong)化極氣(qi)體保(bao)護(hu)焊、藥芯焊絲氣(qi)體保(bao)護(hu)焊或鎢極弧(hu)焊將屏(ping)柵、金屬絲網(wang)或延伸金屬焊接(jie)到鋼(gang)結構框架上(shang)，焊接(jie)襯(chen)片，進行(xing)焊接(jie)時(shi)金屬絲網(wang)容易產生(sheng)燒穿(chuan)和(he)焊縫未熔(rong)合現象，船用焊接(jie)襯(chen)片，應如何進行(xing)處(chu)理？

在金屬(shu)(shu)絲網(wang)或延伸金屬(shu)(shu)上放(fang)(fang)置(zhi)非金屬(shu)(shu)墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)并(bing)且將(jiang)墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)、金屬(shu)(shu)絲網(wang)和框架夾(jia)緊在一(yi)起，不(bu)允許采(cai)用(yong)含鉻或鍍鋅墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)，墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)應采(cai)用(yong)未涂(tu)敷的(de)，在被焊位(wei)置(zhi)的(de)墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)上部放(fang)(fang)置(zhi)一(yi)個(ge)更(geng)大(da)的(de)墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)作為散熱片(pian)。上墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)應具有一(yi)個(ge)比下墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)更(geng)大(da)的(de)孔(kong)，以避免上墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)也被焊接(jie)在一(yi)起。然后通過(guo)墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)的(de)兩個(ge)孔(kong)進(jin)(jin)行塞焊，應使(shi)焊縫(feng)處(chu)于下墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)部分。操作者(zhe)可以采(cai)取一(yi)些(xie)其他的(de)方法(fa)得到足夠的(de)熱量并(bing)進(jin)(jin)行焊接(jie)，陶瓷(ci)焊接(jie)襯片(pian)，注(zhu)意(yi)要防止周圍屏柵或金屬(shu)(shu)絲網(wang)燒穿， 另一(yi)種方法(fa)是(shi)采(cai)用(yong)一(yi)個(ge)帶孔(kong)的(de)金屬(shu)(shu)板條，將(jiang)孔(kong)對準需要焊接(jie)的(de)部位(wei)，并(bing)放(fang)(fang)置(zhi)散熱墊(dian)(dian)(dian)(dian)(dian)圈(quan)(quan)，然后進(jin)(jin)行塞焊。

焊前準備

將兩塊(kuai)5083鋁(lv)合金試板(ban)（試板(ban)尺(chi)寸(cun)350mm×150mm×8mm)組對固(gu)定，坡(po)口(kou)(kou)型式(shi)及(ji)尺(chi)寸(cun)參(can)照(zhao)《GB/T985-鋁(lv)合金坡(po)口(kou)(kou)》進行(xing)加工，詳見圖(tu)2。接著用不銹鋼絲刷(shua)將裝配好(hao)的試板(ban)的坡(po)口(kou)(kou)面(mian)及(ji)坡(po)口(kou)(kou)正反(fan)(fan)面(mian)兩側30mm范圍(wei)內的氧化膜認真清除干凈，直(zhi)到露出金屬光澤(ze)為(wei)止。后，將陶(tao)瓷襯墊(dian)塊(kuai)左右兩側鋁(lv)箔膠粘帶上防固(gu)粘紙撕(si)掉，襯墊(dian)中心(xin)線(xian)對準焊(han)縫中心(xin)線(xian)，把襯墊(dian)貼(tie)緊在坡(po)口(kou)(kou)反(fan)(fan)面(mian)。
