Hand-held laser welding: Highest precision, fast welding and easy to learn

Manual laser welding is a technology that enables the welding of materials with high precision and efficiency. It is a form of laser welding in which the laser beam is directed onto the material to be welded via a hand guide. This technology is particularly suitable for processing thick, thin and reflective metals without causing distortion, deformation, undercutting or burn-through.

One advantage of manual laser welding is its high precision and accuracy. By using a very narrow laser beam, very precise and clean welds can be produced. In addition, hand guidance allows flexible handling and reaching hard-to-reach areas. Hand-guided laser welding is also a very efficient technology, as it allows materials to be welded quickly with minimal material loss and is easy to learn.

Another advantage of handheld laser welding is its ability to weld a wide range of materials, including metals such as stainless steel, aluminum, titanium, nickel alloys and copper, as well as alloyed materials. It is used in a wide variety of applications. These include the manufacture, repair and maintenance of products in mechanical engineering, the automotive industry, aerospace and medical technology.

More productivity and flexibility due to less heat input and distortion

TIG welding generates extreme heat that can deform thin materials. Copper is difficult to weld with this method, and there is limited capacity for metals of varying thickness. MIG welding requires wire that is consumed, pre-cleaning of the material, and beveled edges on thick metals to achieve a full penetration weld. The working area and possible angles are limited, and vertical positions are extremely difficult. LightWELD, an IPG product, offers an alternative to these conventional welding methods. It enables much faster welding and is easier to learn and use. For a wide range of materials and material thicknesses, it delivers more consistent and higher quality results than MIG and TIG welding with less distortion, deformation, undersize and burnout. Utilizing the latest laser welding technology, LightWELD allows dissimilar metals of varying thicknesses to be welded with little effort and produces strong, aesthetic joints with little or no wire.

With LightWELD, you can switch quickly and easily between different welding modes. This enables you to achieve consistently high welding quality. Even less experienced users only need a short briefing and are able to work like an experienced welder after a short time.

Modes include wobble parameters for wider welds and workpieces with a poor fit. Advanced users can create and save programs for material combinations and switch directly between modes. Pre-saved modes can be used by less experienced operators to achieve the same results, increasing productivity and reducing scrap.

With IPG's LightWELD handheld laser welding system, you can weld faster, easier, more accurately and more flexibly than with traditional welding methods.

LightWELD material spectrum

Material Stärke Einseitige Schweißung Stärke Doppelseitige Schweißung
Edelstahl bis zu 4 mm bis zu 10 mm
Verzinkter Stahl bis zu 4 mm bis zu 10 mm
Baustahl bis zu 4 mm bis zu 10 mm
Aluminum bis zu 4 mm bis zu 10 mm
Kupfer bis zu 1 mm bis zu 2 mm

With IPG LightWELD, thick, thin, reflective and dissimilar metals can be welded wirelessly, which is difficult or impossible with conventional methods. Materials with different electrical conductivity can also be processed, which expands the application range and increases flexibility.

IPG LightWELD can be used to weld metals that are difficult or impossible to work with TIG welding, such as copper and materials with high and low electrical conductivity. Thick metals can also be welded to thin sheets and thin joints. With this handheld laser welding system, seams and corners can be welded with little or no wire, allowing aesthetically pleasing fillet welds for strong joints without excess metal. Significantly less finishing work, such as grinding or polishing, is also required, reducing labor costs. In addition, no cleaning or disposal is required. In addition to laser welding, the LightWELD XC and LightWELD XR models offer the option of laser cleaning. Pre-weld cleaning can be used to remove oxides, rust, paint, oil or grease from the surfaces being welded. Post-weld cleaning removes soot and welding-related contaminants. This increases the quality and precision of welded joints and facilitates equipment maintenance. With IPG LightWELD you have a versatile and powerful solution for your welding needs.
