Suppression of welding defects in deep penetration CO2 laser welding
ICALEO 2000: Proceedings of the Laser Materials Processing Conference, 2000Characteristics of deep penetration welding have been investigated using 20 kW CO2 laser facility. Formation mechanism of the porosity has also been discussed. The porosity forms most significantly for upper focussing conditions, under which the low power density of the laser beam tends to incline the keyhole front wall at the root.

The flow of heat and the motion of the weld pool in penetration welding with a laser
Journal of Applied Physics, 1985Lasers are well suited to penetration welding as they can supply large amounts of power to a very small volume far from the surface of the workpiece. This paper reports the results of calculations performed with the aid of a mathematical model for the flow of heat and the motion of the molten metal surrounding the keyhole formed by the laser.

Fatigue strength of welded armor steels with different weld penetration
Materials TestingAbstract Armor steels are crucial for their high hardness and toughness, providing protection in military and security applications, including vehicles and personal body armor. This study aims to assess the fatigue strength of welded armor steels having different weld penetration. Weld fusion or penetration (FOP) is an important issue in

The influence of the stud arc welding process parameters on the weld penetration [PDF]
Scientific Bulletin. Serie C, Fascicle Mechanics, Tribology, Machine Manufacturing Technology, 2009 Due to short time of welding cycle, simplicity in equipment use and cost efficiency the application of stud arc welding process is well known in various manufacturing fields. In this paper, the influence of welding parameters (welding current, welding time, stud plunge and lift) during Drawn Arc Welding process with ceramic ferule on the weld ...
