Laser welding is a precise process of fusing metal parts using a beam of laser light. It has found numerous applications across most industries, particularly in the automation of small-component welding, where tight control means there’s no need for cleanup. This is most useful in the automotive, aerospace, and electronics sectors, where precision and efficiency are the biggest driving factors. Handheld laser welding machine is an inevitable trend in the development of laser welding

TIG welding is a time-consuming, two-handed welding method that requires an experienced, highly-skilled operator. TIG welding may generate extreme heat that deforms thin materials, produces poor visual finishes, is difficult when welding copper, and limited when welding metals of dissimilar thicknesses.
MIG welding requires consumable wire, material pre-cleaning and beveled joints for thick metals for full penetration. Travel and work angles are limited and vertical positions are extremely challenging.
Comwelder Handheld Laser Welding enables dramatically faster welding, is easier to learn and operate, and provides higher-quality, consistent results across a wider range of materials and thicknesses than MIG or TIG with minimal distortion, deformation, undercut or burn-through.
The low heat input and extensive material and thickness capabilities increase productivity, repeatability, and improve weld quality for operators of all skill levels. Comwelder handheld laser welding welds dissimilar metals of different thicknesses with ease and creates aesthetic high-strength joints with minimal or no consumable wire.
