Joining dissimilar materials – the process of high beam welding

 

electron beam weldingHigh beam welding, a fusion welding process, uses a high-velocity beam to join two materials. This process uses kinetic energy, which causes work pieces to melt and flow together to form a joint. A high beam welder is able to take two different metal pieces and join them, something that is unable to be done with several other welding processes.

It isn’t usually possible to join metal pieces that have different properties and alloys when welding. However, by using high beam welding in a vacuum, this task can be performed. Basically, the high beam welder lowers only one piece to the melting point, while the other work piece remains in a solid state.

One of the advantages of using high beam welding is that you can localize the heating process with precision and control, putting the energy exactly where it is needed for the process. The vacuum also contributes to a quality weld of the two parts.

Of course, high beam welding may also have some drawbacks. With the cooling of the melted piece, solidification may cause cracking, deformation and a change in the shape of the work piece, depending on the conditions of the piece during solidification.

Overall, high beam welding is one of the only processes available to properly weld dissimilar metal pieces, making it a necessary application in the manufacturing industry.
