				process.

				title of the desired specification).

				position or positions in which the welding will be done. See
				§14-15.13.).
PREPARATION OF BASE MATERIAL. The edges or surfaces of the
				parts to be joined by welding shall be prepared by ________ (state whether
				sheared, machined, ground, gas cut, etc.) as shown on the attached sketches and
				shall be cleaned of all oil or grease and excessive amounts of scale or rust,
				except that a thin coat of linseed oil, if present, need not be removed. (The
				sketches referred to should show the arrangement of parts to be welded with the
				spacing and details of the welding groove, if used. Such sketches should be
				comprehensive and cover the full range of material or base metal thicknesses to
				be welded.)
NATURE OF ELECTRIC CURRENT. The current used shall be
				________(state whether direct or alternating and if alternating give the
				frequency). The base material shall be on the ________ (state whether negative
				or positive) side of the line.
WELDING TECHNIQUE. The welding technique, electrode sizes, and
				mean voltages and currents for each electrode shall be substantially as shown
				on the attached sketches. (The sketches referred to may be the same as
				mentioned under "Preparation of Base Material" or may be separate sketches.
				They should show, for the minimum thickness and for several intermediate
				thicknesses of base material, the welding technique to be used, whether weaving
				or beading, the number of layers or passes and diameter of electrode with the
				mean voltage and current for each layer or pass, and in the case of vertical
				welds, the progression of each pass-whether upward or downward.)
Note: Since, in the welding of many materials in the flat
				position and particularly for the ordinary mild steels, the proper welding
				"heat" can be readily determined by the appearance of the individual beads of
				welding, the use of a "Standard Appearance Weld" may be desirable for the flat
				position. Such a weld should be made in the maximum thickness that will be used
				in construction, except that the maximum thickness of the standard appearance
				weld need not exceed three-quarters inch, and should show approximately two
				inches of the surface of each layer and a cross section through the weld at
				each layer, where such ross section is found necessary to produce a clearly
				understandable photograph. When a standard appearance weld is used the
				following paragraph should be used in lieu of specifying current and voltage
				values.
APPEARANCE OF WELDING LAYERS. The welding current and manner of
				depositing the weld metal shall be such that the layers of welding as deposited
				shall have the appearance shown on the photographs attached hereto. There shall
				be practically no undercutting on the side walls of the welding groove or the
				adjoining base material.
CLEANING. All slag or flux remaining on any bead of welding
				shall be removed before laying down the next successive bead.
DEFECTS. Any cracks or blow holes that appear on the surface of
				any bead of welding shall be removed by chipping, grinding, or gas gouging
				before depositing the next successive bead of welding.

				part of the specifications, a description being given of the degree of peening
