| Abstract: | Transient liquid phase diffusion bonding is more and more widely used in the welding filed, which has many advantages such as low welding temperature, high dimensional accuracy of the connecting member, small residual stress and high joint strength. An oil-gas pipeline maintenance scheme by using the transient liquid phase diffusion bonding was pres- ented in the paper. Moreover, a feasibility analysis was undertaken and a liquid phase diffusion welding machine was de- signed. The main structure includes clamping structure, heating and gas protection system,pressurized system and control system, each system was given a detailed introduction. The welding machine with simple structure and convenient operation has higher market promoting values. |
