Treatment for LS and LP. Often, no treatment is needed. If you have severe LS or LP, you will need to see your doctor regularly. If symptoms such as itching or soreness become troublesome, it can help to use a non-perfumed moisturiser instead of soap on the vulval area.
Gas tungsten arc welding (GTAW), or tungsten/inert-gas (TIG) welding, is a manual welding process that uses a non-consumable electrode made of tungsten, an inert or semi-inert gas mixture, and a separate filler material.
Corrosionpedia explains Welding Process. In the welding process, metal is melted to bridge the parts to be joined, so that on solidification of the weld metal the parts become united. Welding is often done with pressure, sometimes in conjunction with heat, to produce the weld.
