Where is the filler metal inserted when depositing beads with filler metal?

The heat of the torch should be concentrated on the base metal when depositing weld beads with filler metal. 8. The filler metal should be positioned in the weld pool along the entire length of the joint when welding.

What holds the filler metal in place on an open root weld?

Surface tension holds the metal in place, and the mass of the lead quickly cools the molten weld pool holding it in place. Increasing the electrode angle toward the perpendicular will increase penetration depth and possibly cause more burn through.

When carrying a weld pool without filler metal the inner cone of the flame should be held approximately 1 8 from workpiece?

When carrying a weld pool without filler metal, the inner cone of the flame is held approximately 1/8 from the workpiece. Filler metal with a diameter approximately equal to the thickness of the base metal being welded should be used. When welding in flat position, the filler metal is held at a 90 angle.

How are smooth even ripples formed in a weld bead?

Why is a filler metal used in welding? … How are smooth, even ripples formed in the weld bead? Uniform torch movement will produce smooth, even ripples. If cast iron has been properly welded, where should the break occur when the completed weld is tested?

What is the outer surface of the weld bead on the side the weld was made?

The weld face is the outer surface of the weld bead. As previously mentioned, the weld toe is the point where the weld face touches the surface of the base metal. A fi llet weld is made up of three primary dimensions. The fi llet weld size is the length of one side.

What is filler pass?

Fill – Also referred to as a fill pass, it is the amount of weld bead necessary to fill the weld joint. This pass comes after the root pass and before the cap pass (see next). … It allows for good penetration and tie-in in the completed weld. All about the arc. Arc characteristics are important in any welding process.

What is the area where filler metal intersects the base metal that is opposite to the face?

Weld Root– The points at which the root surface intersects the base metal surfaces. Joint Root – That portion of a joint to be welded where the members approach closest to each other. In cross section, the joint root may be a point, a line, or an area.

What primary function do filler rods serve in oxy-acetylene welding?

The process of fusing metals together using the oxy-acetylene flame as a heat source with the addition of a filler rod for added strength.

Which material Cannot be cut by the oxyfuel process?

Oxy-fuel cutting cannot cut non-ferrous metals such as aluminum, stainless, brass or copper. Elements such as chromium, nickel, molybdenum inhibit the ability to cut steel with the oxy-fuel process. Manganese, silicon, phosphorus, and sulfur in normal amounts have little effect on the cutting process.

When a non ferrous filler metal is applied but is not distributed in the joint by capillary action it is called?

Braze welding begins to melt at the tempature of 840F below the melting point of the metals jointed and in which the filler is not distribued into the joint by capillary brazing using non ferrous filler metals that have a melting point below that of the base metal. Define the term “tinning”

Why is a filler metal used in welding?

Filler metals are alloys or unalloyed metals which, when heated, liquefy and melt to flow into the space between two close fitting parts, creating a brazed or soldered joint. … Filler metals produce joints that meet service requirements, such as strength and corrosion resistance.

What is the difference between a stringer bead and a weave bead?

Stringer beads are recommended for welding all carbon and low alloy pipe in the vertical-fixed position. The advantage of using weave beads, in the rolled or horizontal-fixed position, is that it requires less time to complete the welds.

What weld is the point where the weld bead contacts the base metal surface?

The weld toe is the point where the weld bead contacts the base metal surface. It occurs twice on each weld bead. Root reinforcement is the distance that the penetration projects from the root side of the joint.

What are edges of a weld called?

The toes of the weld are essentially the edges or the points of the hypotenuse. The face of the weld is the outer visual or hypotenuse that you see when looking at a fillet weld. The legs are the other two sides of the triangular fillet weld.

When a weld is made on the side of the joint that the arrow touches the symbol for that weld is always shown below the reference line?

When a weld is made on the side of the joint that the arrow touches, the symbol for that weld is always shown below the reference line. The vertical line used in the bevel, fillet, and “J” groove joint symbol is always drawn tot he left side of the symbol drawling.
