A Review on Laser-Assisted Joining of Aluminium Alloys to Other Metals
Laser Beam and Laser-Arc Hybrid Welding of Aluminium Alloys
Root formation and metallurgical challenges in laser beam and laser-arc hybrid welding of thick structural steel
Thermo-mechanical tensile testing of geothermal casing materials
Ultra-high temperature geothermal wells (>450 °C) have a large potential for increased energy yield as compared to conventional high-temperature geothermal wells (200-300 °C), but several research challenges must be resolved before robust operation in this temperature range can be achieved. In this...
Evaluation of Casing Collapse Capacity in Ultra-High Temperature Geothermal Wells
A common cause of casing failure in geothermal wells are due to collapse caused by compressive hoop stress that occurs during heating of the well. In traditional design, the empirical formulas from API TR 5C3 are applied for determining the casing collapse capacity. However, the experimental data...
