(State class of object to be welded)
Specification No.
_________
 
Date _________
PROCESS. The welding shall be done by the metal are process.
BASE METAL. The base material shall conform to the specifications for __(insert here references to standard A.S.T.M. or other Code designations, or give the chemical analysis and physical properties).
FILLER METAL. The filler metal shall conform to classification number __of the A.S.M.E. specification for __ (insert here the title of the desired specification).
POSITION. The welding shall be done in the __ (give the 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.
PEENING. (If peening is to be used, it shall be incorporated as part of the specifications, a description being given of the degree of peening to be done.)
TREATMENT OF UNDER SIDE OF WELDING GROOVE. (The method of preparing the under or second side of a groove for welding on that side should be stated in this paragraph.)
