Laser beam welding effectively uses energy from the laser beam itself to melt and join the same metals and also dissimilar metals to one another. Some of the main advantages of laser beam welding are its rapid speed (up to 10 times faster than TIG welding), highly repeatable results, accuracy to allow for problematic deep narrow welds to be completed.
Laser beam welding is a fusion joining process that uses the energy from a laser beam to melt and subsequently crystallize a metal, resulting in a bond between parts. Laser beam welding can be successfully used to join many metals to themselves as well as to dissimilar metals. Main applications are related to welding steels, titanium, and nickel alloys.
When the laser beam makes contact with the metal(s), the energy is converted from light to thermal energy. Concentrating the laser on an area as small as 0.2 mm in diameter, the heating effect is magnified greatly. Providing the laser power is calibrated correctly, the weld area (where the two pieces meet) will melt and then crystallize, fusing the parts together. If the laser is too powerful the laser may heat the material beyond the point of vaporization and simply slice straight through it. It is therefore important that the laser beam be set up to operate for the specific application being considered.
The action of the laser beam that leads to the formation of a welding cord can be decomposed following the stages below (Figure 1):
Advantages of laser beam welding
High productivity (nearly 10 times faster than TIG).
Disadvantages of Laser Welding
Applications of Laser Welding
Used in electronics industry for applications such as connecting wire leads to small electronic components, to weld medical equipment, transmission components in automobiles and in cladding process.

标题 摘要
The Total Materia database contains many thousands of materials suitable for welding applications across a large range of countries and standards.
Where available, full property information can be viewed for materials including chemical composition, mechanical properties, physical properties and carbon equivalent data as well as advice on welding application.
Using the Advanced Search page, define the search criteria by selecting ‘Welding filler materials’ in the Group of Materials pop-up list. It maybe that you need to further narrow the search criteria by using the other fields in the Advanced Search page e.g. Country/Standard.
Then click Submit.
A list of materials will then be generated for you to choose from.
After clicking a material from the resulting list, a list of subgroups derived from standard specifications appears.
From here it is possible to view specific property data for the selected material and also to view similar and equivalent materials in our powerful cross reference tables.
Click on the property data link of interest to you to view specific property data.
For you’re a chance to take a test drive of the Total Materia database, we invite you to join a community of over 150,000 registered users through the Total Materia Free Demo.
