Welding Tungsten Boat
1. Description of Welding Tungstenn Boat:
Heated tungsten boats, also known as welding tungsten boats, are made by high-temperature welding two tungsten plates together. The steam holes at the bottom of this form of tungsten boat are pretty loose and may be found all over it. The boat is also relatively dense. It has a high temperature tolerance of up to 2600 degrees. The size of this kind of tungsten boat is relatively enormous because the welded tungsten boat is created by fusing more than two tungsten plates.
2. Size and physical characteristics of welding tungsten boats:

5. Advantage of Welding Tungstenn Boat:
The welded tungsten boat has a size that is relatively large and can be used to evaporate huge devices or a lot of materials since it is formed of five pieces of tungsten plates that have been joined together. Welded tungsten boats can save 10% to 20% on materials over riveted tungsten boats while also reducing labor-intensive procedures like scribing, drilling, and assembly. Additionally, using a welded structure allows you to choose your materials based on their intended usage, which is more economical. The boat made of welded tungsten is airtight.
