Laser Beam Weld

[artnmotion]

Does anyone know the symbol for LASER BEAM WELDING? (Cylinders)

Are you asking what the symbol means on your attached image? If so, then the symbol means:

LBW = Laser Beam Welding
circle = full circumference
rectangles = edge welding


Your weldment image looks more like a lap joint with a fillet weld, which would use a triangle symbol instead of a rectangle.

I agree that your sketch appears to show the edge of a thin wall cover fillet welded to the OD of the thick wall cylinder it is placed over. However, your joint design is probably not optimum for a laser welding process. It would help to modify the joint for a butt type weld, where the radially directed laser beam fuses two edges of similar local thickness.
