Effect of Bonding Pressure on Microstructure and Properties of TLP Joint of 20 Steel Pipes |
| |
| Abstract: | When the welding temperature is 1180℃, holding time is 3 min, bonding was carried out using BNi2 as interlayer in an argon atmosphere. The effect of welding pressure on the microstructure and mechanical properties of TLP bonding joint were studied. The element distribution of the joints was examined. The result shows that the best welding pressure parameters of TLP of 20 steel pipes is 4 MPa. |
