in branch connections, reinforcement is material around a branch opening that serves to strengthen It. The material is either integral in the branch components or added in the Form of weld metal, a pad. a saddle, or a sleeve. In welding, reinforcement is weld metal in excess of the specified weld size.
a structural attachment, device, or mechanism that limits movement of the pipe in one or more directions. See pipe alignment guide.
sererse polarity: the arrangement of direct current arc welding leads with the work as the negative poic and the electrode as the positive pole of the welding arc; a synonym for direct current electrode positive
root opening: the separation between members to he joined at the root of the joint,
mat penetration: the depth that a weld extends into the root of a joint measured on the centerline of the root cross section.
root reinforcement: weld reinforcement at the side other than that from which welding was done.
the exposed surface of a weld on the side other than that from which welding was done.
run: we main.
seal weld: a fillet weld used on a pipe joint primarily to obtain fluid tightness as opposed to mechanical strength; usuaLly used in conjunction with a threaded joint.
arc welding: arc welding with equipment that controls only the filler metal The advance of the welding is manually controlled.
shall: LLwd to indicate that a provision or prohibition in this Code is required. i.e., mandaloty
shielded metal arc welding (SMAW): an arc welding process in which coalescence is produced by heating with an electric arc between a covered metal electrode .md the work. Shielding is obtained from decomposition of the electrode covering. Pressure is not used and filler metal is obtained from the electrode.
should: used to indicate that a provision of this Code is not required but represents good practice.
single-welded butt joint: a butt joint welded from one side only.
sre of weld
fillet weld: for an equal leg fillet weld, the leg length of the largest isosceles right triangle that can b inscribed.
