An Introduction to metal-cored wire - The FABRIOR
Metal-cored wire can weld thin materials without burn-through because it lacks a "deep finger" of penetration. Also, spray transfer requires less amperage with metal-cored wire. On thinner metals (1/8 in. or less), metal-cored wire may let you switch from short-circuit to spray transfer to improve travel speeds, bead appearance, and bead quality.

2008/3/4· Calcium metal reacts with water, evolving hydrogen gas at a rate rapid enough to be noticeable (unlike its sister magnesium) but not fast enough at room temperature to generate much heat. Part of the slowness of the calcium-water reaction results from the metal being partly protected by insoluble white calcium hydroxide.
