1 SMAW Agriculture Science 1

2 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.

3 Why arc weld?  Who has arc welded before?  Careers in Arc welding  Versatility

4 Careers  Inspector/Expeditor  Rail Road-Bridge Crew, Welder  Welding Engineer  Welder Weld Engineer  Associate Steel Inspector  Underwater Welding  Sales Manager

5 Versatility  Weld almost any metal  Strength  Cost effective  Durability of weld  Most common type of welding  Repair work  Employment  Ability to weld in difficult places

6 Safety  Safety Glasses  Welding Helmet  Gauntlet style gloves  100% Cotton Clothes-LONG SLEEVES!  No cuffs in pants or frays  Leather Boots  No Watches  Flammable Liquids on Clothes

7

8  One glove missing  Improper gloves  Apron tied in front  Wearing a watch  Tie not tucked in  No safety glasses  Wearing a ring  Pants are cuffed

9 Welding Terms  Electrode  Electrode Holder  Ground  Root Pass  Filler Pass  Cover Pass  Slag  Spatter  Undercutting  Tack  Arc  Amperage  Flux

10 Electrode Classification E 6013 E - Electrode 60 – Products minimum tensile strength: 60 = 60,000 psi 1 - Welding position: 1 = ALL, except vertical down 3 – Indicates coating type (RUTILE), welding current and polarity

11 Techniques  Stringer (drag) (whip)  Weave  circles  crescent  zig zag  box weave  stitch

12 Weld Bead  A weld resulting from a pass Stringer Bead Weave Bead

13 Passes  Weld Pass - A single progression of welding along a joint. The result of a pass is a weld bead or layer

14 Root PassHot Pass Fill PassCover Pass

15 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
