Beam welding of electrons in the aerospace industry

Advantages and disadvantages

What are the advantages and disadvantages of electron beam welding (EBW) in comparison with other forms of welding? I am not very familiar with this problem and I am interested in understanding the common uses of EBW, things to watch out for certification and that an operator needs to be qualified for this type of welding.

Electron is an automatic process. Is usually done with Robotics full equipment. The advantages are that it produces an excellent welding quality, the deep penetration, While at the same time, minimizing heat input of global time.

Another advantage is under contract with electron beam welding even extremely thin materials can be easily welded. You can also weld thickness in one pass. It is only possible to achieve near 0% rejection rate with a strict management and experienced operators. The main disadvantage is the cost. Aerospace PCV is by far the more expensive welding process. EBW requires a vacuum chamber with a vacuum that is difficult to achieve. Only small to medium-sized items can be welded. Although welding can be done very quickly, EBW generally takes a long time. The equipment is complex and there are very few process variables in question. In other words, more ways to do evil, or according to Murphy's law “If there is a way to do it wrong, somebody else will.” The most common applications are high performance where weld quality and integrity is essential, along with very low distortion. For example, aircraft engines and aircraft parts. It is also used for the titanium and otherwise difficult to weld materials, such as, magnesium and exotic alloys. EBW is also used for soldering electronic precision.
