   The shadow mask is installed to the screen using metal pieces [350] or a rail or frame [351] [352] [353] that is fused to the funnel or the screen glass respectively, [258] holding the shadow mask in tension to minimize warping (if the mask is flat, used in flat-screen CRT computer monitors) and allowing for higher image brightness and contrast.

3. Friction stud welding - Wikipedia

   en.wikipedia.org/wiki/Friction_stud_welding

   friction plug welding; Portable equipment for friction stud welding is available for use on construction work sites, offshore, underwater and in workshops. These portable units are much lighter and smaller than the large static friction welding machines which are used, for example, in factories to weld engine components such as drive shafts.

4. Welding - Wikipedia

   en.wikipedia.org/wiki/Welding

   Other arc welding processes include atomic hydrogen welding, electroslag welding (ESW), electrogas welding, and stud arc welding. [46] ESW is a highly productive, single-pass welding process for thicker materials between 1 inch (25 mm) and 12 inches (300 mm) in a vertical or close to vertical position.

5. Gas tungsten arc welding - Wikipedia

   en.wikipedia.org/wiki/Gas_tungsten_arc_welding

   GTAW weld area. Manual gas tungsten arc welding is a relatively difficult welding method, due to the coordination required by the welder. Similar to torch welding, GTAW normally requires two hands, since most applications require that the welder manually feed a filler metal into the weld area with one hand while manipulating the welding torch in the other.

6. Friction welding - Wikipedia

   en.wikipedia.org/wiki/Friction_welding

   The process is used with the addition of a lateral force called "upset" to plastically displace and fuse the materials. [1] Friction welding is a solid-state welding technique similar to forge welding. Instead of a fusion welding process, Friction welding is used with metals and thermoplastics in a wide variety of aviation and automotive ...

7. Shielded metal arc welding - Wikipedia

   en.wikipedia.org/wiki/Shielded_metal_arc_welding

   Shielded metal arc welding (SMAW), also known as manual metal arc welding (MMA or MMAW), flux shielded arc welding [1] or informally as stick welding, is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld.
