Although some engineers have had success in spot welding steel and aluminum together, it has largely been considered impossible to achieve reliable, continuous welds directly between the two ...

To address the challenge of porosity suppression in laser-arc hybrid welding of high-nitrogen steel, a weakly coupled laser-arc welding method suitable for high-nitrogen steel is proposed. A test ...

Laser welding of dissimilar materials, such as steel and copper, is highly susceptible to crack formation, which compromises joint integrity and service life. Traditional inspection techniques are ...
