The now available long-range supervision system at home and abroad is based on the optical fiber mostly, and if the optical fiber runs into that the machinery lashes and colliding optical fiber may split or break. Once splitted, it's hard to be restored because of the sophisticated equipment, and ordinary user can't restore it by means of the welding at all. Moreover the high price of light transmitter and light receiver limits the application and popularization.

国内外现有的远程监控系统大多基于光纤，而光纤如果遇到机械冲击、碰撞等都会造成光缆断缆或断芯，光缆断裂后，很难快速修复，且修复设备复杂，普通用户根本无法进行焊接修复，再加上光端机价格较高，这些都限制了光纤远程监控系统的应用和普及。

Mechanisms of heat affected zone liquation and liquation cracking in GH150 alloy were investigated by using varestraint test and hot ductility test in conjunction with the differential thermal analysis and optical, scanning electron microsopy. On heating,γ/C liquation take places in the HAZ above 1250℃. When the temperature reaches 1353- 1375℃, a large amount of liquid particles due to initial melting can be observed within the grains near the fusion boundary. On cooling,γ/C eutectic and γ/ Laves phase eutectic take place at 1273 and 1200℃ respectively.

采用可变拘束试验、热塑性试验、差热分析、光镜与扫描电镜观察，研究了GH150合金焊接热影响区液化及液化裂纹形成机制加热过程中温度高于1250℃的热影响区由于γ／C共晶产生液化，在温度达到1353℃（固相约至1375℃的近维区，晶内出现大量液化点冷却过程中温度在1273和1200℃时形成γ／C共晶和γ／Laves相共晶。
