1 what is sheilded arc welding 2 what are some safety precautions for sheilded arc welding

  • 1. Shielded arc welding is a fusion process where heat is obtained from an electric arc which is formed between a base metal and an electrode.

  • 2.Some safety precautions are:

    • A)Don't strike arc until helmet is in place

    • B)Wear proper clothing

    • C)Hold electrode by insulated handle

    • D)Proper ventilation

    • E)Avoid welding near combustable material

    • F)Always wear safety glasses

    • G)Never stand in water when welding

    • H)Never weld on closed conainers

  • 3.Hold the elctrode at a 15 degrees travel angle and either tap or strike an arc then position electrode 1/8 inch from metal.

  • 4.Some basic welds are Butt, Tee, Lap V, and positions are Flat, Horizontal, Vertical and Overhead.

  • 5.Some equipment is:

    • A) GrinderE) Chipping Hammer

    • B) HelmetF) Clothes

  • C) ViceG) Helmet

  • D) Wire BrushH) Pliers

  • 7.An electrode is a metal rod coated with Flux the numbers on the rod stand for 601 1 -

  • 60 = 60,000 lbs per square inch

  • XX 1 = Position1 =All 2 = Flat and Horizontal 3 = Flat

  • XXX 1 = Polarity

  • 1,3,4,8=AC or DC Reverse 2 = AC or DC straight 0 = DC Reverse

    • 8.Metal should be cleaned of oil, paint, rust, and ground to bevel if over 1/4".

    • 9.Cutting is done by turning amps up 150% and pushing rod through metal.

    • 10. The amp setting is determined by the rod size and metal thickness

    • 11. The size of rod used is based on the thickness of metal.
