SMAW Agriculture Science 1
SMAW Shielded Metal Arc Welding Stick welding Arc Welding A welding process where similar materials are joined with a heating process caused by an electric arc. In the most common use, this process includes the use of a filler metal.
Why arc weld? Who has arc welded before? Careers in Arc welding Versatility
Weld Bead A weld resulting from a pass Stringer Bead Weave Bead
Passes Weld Pass - A single progression of welding along a joint. The result of a pass is a weld bead or layer
Root PassHot Pass Fill PassCover Pass
Progression (vertical) Up deeper penetration Higher deposit rate (lb/hr) Use near 90 degree travel angle or slightly up Down faster (point to point) less penetration for thin metal Use steep drag angle
