In this work the welding of 3,0 mm thick grade 5083 aluminium alloy plates using a 3,0 kW Nd:YAG laser with grade 5183 filler wire addition is investigated. The plates were welded as butt joints with air gap sizes 0,5 mm, 0,7mm and 1,0 mm.
The metallurgical characteristics of non-precious alloys using Nd:YAG laser welding Jun-Hee Lee1, Seok-Kyu Choi1 and Min-Ho Hong2* Abstract Background: This study aimed to determine the effect of hardness change according to penetration depth in the
(I) The science of welding heat sources including gas tungsten arc, gas metal arc, electron beam and laser. The interaction of the heat source with the workpiece will be explored and special emphasis will be given to using this knowledge for automatic control of the welding process.
Laser Welding Advantages Precise control of the laser beam offers users several benefits over TIG, MIG and spot-welding: Weld strength: The laser weld is narrow with an excellent depth-to-width ratio and higher strength. Heat affected zone: The heat affected zone is limited, and due to rapid cooling, the surrounding material is not annealed.

This is where fiber laser wire bonding steps in. By coining a standard wire bonder with a fiber laser, high-quality connections can be made between the bond pad and the wire ribbon. The wire bonder tool holds the wire ribbon and the bond pad together, and the laser spot is focused on the bond ribbon, close to the device forming a weld between the ribbon and the pad.

The effect of laser welding parameters, surface cleaning, filler wire addition, and backing strip on quality of laser welded joints was clarified using 5 kW laser machine. It was found that all the investigated alloys showed tendencies for porosity and solidifiion cracking, particularly, at high welding speed ( 4 m/min).
Metallurgical Interactions in Advanced Laser Processing A critical aspect of developing new laser manufacturing technologies is the interactions they may have with the materials being processed, in terms of their effect on the local chemistry, microstructure, texture and properties.
Laser welding systems are now used in many fields to efficiently, economically, and contactlessly make high-quality joints. They result in flawless seams in metal plates, plastic components, jewelry, and even building components. The laser welding equipment

Laser cladding Laser cladding is a process to perform overlay welding using a laser instead of an arc. Deposits a material (normally metallic), known as clad, serves as a support material for repairs, wear prevention and corrosion resistance. Cladding provides
This process is generally called hybrid laser welding, where you introduce wire, much like you would have in a MIG weld appliion, under the focused laser beam. “That wire may be preheated through electrical resistance and a suitable weld power supply, so that the wire …
