WebWelding establishes strong, durable, and permanent joint links. It is a simple process that results in a great finish. The technique, when used with filler material, produces a stronger weld than the base material. It can be performed at any place. It is an economical and affordable process. WebFigure Q2-1. Stratospheric ozone production. Ozone is naturally produced in the stratosphere in a two-step process. In the first step, ultraviolet sunlight breaks apart an oxygen molecule to form two separate oxygen atoms. In the second step, each atom then undergoes a binding collision with another oxygen molecule to form an ozone molecule.
