Symbols for welding positionsor sheet metal and pipeButt weldsEN 287*Symbols for Welding Positionson Sheet MetalFillet weldsEN 287*Downhand position: The parts arein a horizontal plane and the fillermetal is deposited from above.Pipe in rotation; the axis of thepipe is horizontalThe pipe is made to turn duringthe welding, while the filler metalis deposited in the area mostconvenient for the welder or theoperatorPA Fillet (1 F)Fillet welding.The parts are bent kind theweld is in a horizontal plane.The axis of the weld is vertical.Horizontal vertical position: Theparts are in the vertical plane andthe axis of the weld is horizontal.The axis of the pipe is verticalThe welding is carried out on ahorizontal plane.The welding is said to be “inhorizontal fillet”.PB Horizontal Fillet (2 F)Horizontal fillet welding.One part is horizontal and theother vertical.The weld between the twoparts is performed in ahorizontal plane.Stationary pipe:The pipe’s axis is at 45ºThe weld is operated from thebottom toward the top in a 45ºplane in relation to the vertical.The welding is said to be“in an inclined up position”.Vertical position: plates are in avertical plane, as is the axis of theweld.Vertical up position. The metal isdeposited from bottom to top.Stationary pipeThe axis of the pipe is horizontal.The weld is carried out from thebottom toward the top on avertical plane. The weld ispositional “positional”Vertical position: plates arevertical, as is the axis of the weld.Vertical down position. The metalis deposited from top to bottom.Stationary pipeThe axis of the pipe is horizontal.The weld is carried out from thetop toward the bottom on avertical plane.
