Fiber Laser Welding Machine Reduces Spatter, Cracking
Coherent’s CleanWeld fiber laser is said to minimize cracking and porosity and to reduce as much as 80 percent of spatter. It also enables certain welding processes to be performed with less laser power, says the company. CleanWeld is complemented by ARM fiber laser technology.
According to the company, CleanWeld applies a variety of techniques—including intensity distribution of the focused laser spot, beam motion and controlled vapor evacuation—in order to control and maximize the stability of the keyhole and melt pool.
Applications for the fiber laser include zero-gap welding of galvanized steel, automobile powertrain component welding, and aluminum and copper welding for electric car batteries, according to the company.
The potential benefits of using waterjet technology to produce parts or part features smaller than 300 microns are compelling. Developers and researchers are getting close to breaking the barriers that stand in the way of micromachining in the 150- to 200-micron range and below.
Machine with abrasive waterjet and control the depth of cut. For the right parts, this fledgling process may offer a compelling alternative.
Consider these alternatives when conventional drilling can't do the job.
