... sheets are welded around the periphery to form a closed envelope. The sheets can be welded by either resistance seam welding or by laser welding; what is important is that the weld joints are vacuumtight and capable of resisting up to 1.38 MPa (200 psi) gas pressure. To prevent the two sheets from...
