About This Webinar
In general manufacturing applications, arc welding creates a large heat-affected zone (HAZ) that can cause distortion in the joined materials. Arc welding may also require multiple passes, consuming extra time and energy. Laser welding overcomes these challenges by concentrating energy in a smaller area than traditional arc methods can, to penetrate deeper into the material and achieve a smaller HAZ with little to no distortion. Laser welding’s flexibility makes it suitable for joining a range of materials of varying thicknesses, and allowing noncontact, single-sided processing and noncontinuous welding operations. But even laser welding has its challenges.

Shekel covers the challenges that standard lasers face when welding thick materials such as solidification cracks, and then he explains how dynamic beam laser technology can overcome such limitations by reaching penetration depths in the tens of millimeters at power levels up to 100 kW.
