焊接熱劑
英文
welding thermit-
" blowtorch : a portable burner for mixing gas and oxygen to produce a very hot flame, used for soldering, welding, and glass blowing.
噴燈:使混合氣體和氧氣產生更熾熱火焰的便攜助燃劑，常用於接合、焊接和玻璃吹制。Railway fixed equipment. thermit welding of rails. welds performed by compagnies. performance and acceptance conditons of works
鐵路固定設備.鋼軌熱劑焊.由compagnies執行的焊接.工程特性和驗收條件When flux appears liquid and transparent on both tube and valve, start sweeping flame back and forth along axis of joint to maintain heat on parts to be joined, especially toward base of valve socket
當焊劑變成液態並且在管道和閥門上呈現半透明狀態時，開始將火焰沿著連接部件的軸線進行進退烘烤，以保持連接部件、特別是閥門套筒底座部位的熱度。Products : rectifers, high silicon cast iron anodes, mmo anodes ( rod, tubularribbon ), titanium conductor bar, sacrificial anodes ( aluminum, magnesiumzinc ）, magnesiumzinc ribbon anodes, zinc grounding cell, reference electrodes, test postjunction boxes, thermite ( corrtech exothermic weld metal ) mold, cathodic protection system utilizing solar energy, cp data remote monitoring system, and other accessories

針對上述原因提出了防止氨冷器類臨氨壓力容器產生應力腐蝕裂紋的對策：選用強度稍低，但抗裂性較好的低碳鋼和低合金鋼，如用20r鋼製造；焊接時應採用嚴格的工藝措施和較低的焊接熱輸入量；焊后應及時進行整體消除應力熱處理；控制焊接接頭各區硬度hb 185 ；在液氨中添加0 . 25 %的水作為緩蝕劑；在運行中加強檢查，及時進行停車檢修時的內外部檢查和定期檢驗。Apply flame to valve at base of socket. heat uniformly, sweeping flame from fitting to tube until flux on fitting becomes quite. avoid excessive heating of valve
在閥門的承插口底部進行加熱。要均勻加熱，從連接部到管道掃著火焰，直到連接件上的焊劑不會再發出吱吱聲。要避免過度加熱閥門。It was found that the interfacial bonding of 93w - ofc was both the joining action of ofc / w grains and that of ofc / ni - fe binders, whereas the joining of ofc to tc4 could be seen as the mutual intense diffusion effect between ofc / tc4 and as a result cu - ti intermetallic compounds were formed at the joint. the joining of tc4 - a1 and a1 - mb2 were also attributed to the result of diffusion between elements ti - al and al - mg respectively. on the other hand, residual thermal stress and stress - induced distortion were produced at the joint simultaneously due to the difference in thermal expansion coefficient of different welding " materials
研究表明， 93w與ofc的界面連接是ofc與93w中w晶粒的連接以及ofc與93w中ni - fe粘接劑的連接共同作用的結果； ofc與tc _ 4連接界面的形成是由於ofc與tc _ 4之間發生反應擴散，並由此在二者接頭處生成了cu - ti金屬間化合物的中間相； tc _ 4 - al的連接與al - mb _ 2的連接則分別是其基體元素ti 、 al之間和al 、 mg之間元素互擴散的結果，另外，由於熱膨脹系數的差異，擴散焊接后在不同焊件的接頭處存在殘余熱應力並由此引起接頭的形變。分享友人
