Handheld laser beam systems have attracted a great deal of interest from users in the last two years, especially in the area of welding. This is mainly due to two factors. Firstly, the cost of a corresponding system has fallen significantly in recent years. Secondly, there are advantages of the process and the resulting properties like higher welding speed, less heat input as well as reduced straighten works. The penetration depth and/or dilution can be controlled very precise by the parameter setting. 
The idea of using an optical fiber to guide laser power to a handheld laser head (today often called laser torch) was patented over 50 years ago. Further developments and patents were also granted for laser heads with different material feeds, whether as powder or wire. Due to the massive price decline, the handheld laser processes gained an increasing attention. Beside welding, cleaning and cutting can be done with handheld laser systems as well. Some are dedicated to only one process, others are designed as multipurpose devices.
This document addresses various aspects of handheld laser beam processing, in particular the history and the current state of the art. In addition to joint welding, where HLBW is currently becoming the standard, coating and cladding applications for the production of new parts and repair have recently come to the fore internationally. Advantages as well as resulting properties are included further.
