A small casting made in a moment and fused to the parts it joins: the light, fume and heat of the arc, the machines that make it, what the metal does as it melts and cools, the five common processes from stick to oxy-fuel and the industrial ones beyond, and the engineering that sizes, specifies, inspects and prices a weld. Run every bead on the page, cut it open and hear it.
A course, not a qualification: welding is learnt with the hands, beside an instructor, wearing the protection Vol. II describes, and the code in force is the one that counts. Every arc, bead and sound on these pages is computed by the page; your progress stays in this browser.
