چکیده مقاله
Explosive welding is a solid state joining process, which uses controlled explosionenergy to create a metallurgical bond between dissimilar metals In this research, theinternal coating of 5083 aluminum pipe with 304 stainless steel by explosion weldingmethod by Anfo materials with an explosion speed of 3000 m/s, under different standoffs at a constant exploding load has been investigated Simulation with AUTODYNsoftware has been used to analyze the process parameters such as speed, impact pressure,stress, plastic strain and temperature in the impact area The maximum pressure obtainedin the pressure contours in all simulations shows values between 15 and 30 GPa Theplastic stress in the collision area has reached its maximum value and is around 900 MPaand exceeds the yield strength of the metals to be connected, which will cause theconnection The temperature increase is in the range of300 to 500 degrees Kelvin, whichis lower than the melting temperature of the metals to be joined, and causes a plastic jetstrain in the collision area to reach its maximum value of 900 MPa and exceeds the yieldstrength of the metals to be joined, which will cause the bonding The temperatureincrease is in the range of 300 to 500 degrees Kelvin, which is lower than the meltingtemperature of the metals to be joined and predicts the creation of a quality weld withoutlocal melting
