    176 welding, semiautomatic arc arc welding with equipment which controls only the filler metal feed. The advance of the welding is manually controlled.

    177 welding, shielded metal arc (SMAW) an arc welding process with an arc between a covered electrode and the weld pool. The process is used with shielding from the decomposition of the electrode covering, without the application of pressure, and with filler metal from the electrode

    178 welding, stud a general term for the joining of a metal stud or similar part to a work piece. Welding may be accomplished by arc, resistance, friction, or other suitable process with or without external gas shielding.

    179 welding, submerged arc (SAW) an arc welding process that uses an arc or arcs between a bare metal electrode or electrodes and the weld pool. The arc and molten metal are shielded by a blanket of granular flux on the work pieces. The process is used without pressure and with filler metal from the electrode and sometimes from a supplemental source (welding rod, flux, or metal granules).

    180 weldment an assembly whose constituent parts are joined by welding, or parts which contain weld metal overlay

    181 slug a piece of material used to fill an excessively wide gap or hole. Not normally an acceptable practice.

    182 hot pass a term used to describe the 2nd pass over a root pass.Usually in reference in pipe. In some procedures the 2nd pass is run very hot to assist in burning out "wagon tracks" created by the root pass.

    No, I just honed my copy/paste skills
    (and I wanted those who disagree with welding terms a different thread to argue in )

    I couldn't find the term "glass" in your list. I want to know exactly what Mr. McCormick is referring to when he uses the term "glass".

    Also, I didn't find the definition of "penetration" (as it applies to welding )
    so I will provide the AWS definition: A nonstandard term when used for depth of fusion, joint penetration, or root penetration.

    Root Penetration: The distance the weld metal extends into the joint root.

    Joint Penetration: The distance the weld metal extends from the weld face into a joint, exclusive of weld reinforcement.

    based on those defintions, and of the various fillet and groove weld etchings that I have done, I disagree with Mr. McCormick about penetration not being possible in a multiple pass groove weld.

    I didn't know if this post was better here or on the other threads....
