Other commonly used processes for shop welding are gas shielded metal arc,flux cored arc,and electro-slag welding. Quality control of welded connections is particularly difficult,because defects below the surface,or even minor flaws at the surface,will escape visual detection.Welders must be 2CHAPTER 6.WELDED CONNECTIONS 6.1 INTRODUCTORY CONCEPTS results for this questionWhat are welding procedures?What are welding procedures?They can also provide the instructions for the welder to use in production in order to produce acceptable welds.Usually welding procedures are developed in accordance with a welding code or standard,and with few exceptions*,require that physical weld samples be produced,inspected,and tested to establish qualification.Inspection and Testing for Welding Procedure Qualification

3.Use as few weld passes as possible Fewer passes with large electrodes,Fig.3-7(d),are preferable to a greater number of passes with small electrodes when transverse distortion could be a problem.Shrinkage caused by each pass tends to be cumulative,thereby increasing total shrinkage when many passes are used.4.Place welds near the Welded Wire Fencing - Fencing - The Home Depot4 ft.x 100 ft.Steel Welded Wire The Everbilt 4 ft.x 100 ft.14-Guage welded The Everbilt 4 ft.x 100 ft.14-Guage welded wire is manufactured with 2 in.wide by 4 in.high mesh openings to help keep pests and other critters out of your yard or garden.The wire has a zinc coating which resists rusting and provides long life for the fencing.Welding Nuts Welding Fasteners Projection Weld Nuts Weld nuts are designed and engineered to be welded to another metallic object,providing high strength fastening capabilities in restricted or limited space areas.Weld nuts are available in numerous sizes,shapes,thicknesses,and configurations.
