What is a face of a weld?
in reference to the acutal weld metal-it is the "bead", what you see on top.
What is weld defect?
Under cut: groove formed along the edges of welding bead, thereby reducing the thickness of base metalCracks: Discontinuity in the weld zonePorosity: Holes in the weld metal caused by the entrapment of gasSlag inclusion: An entrapment of slag or other foreign metal actually inside the weld metalLack of penetration: Lack of weld metal actually entering the parentLack of fusion: Lack of thorough and complete mixing between filler metal and base metal
What is weld pool?
A small "pool" of molten metal that is manipulated to crate a weld bead.
What is the meaning of a welding face?

What is the weld reinforcement shall fair smoothly from the weld to the base metal?
It means, that the Weld Bead/ Weld Metal must be very well blended with the Parent Material/ Base Metal. There shall be a smooth transition between the Base Metal and the Weld ( Face or Root ) Reinforcement without any sharp or sudden changes ( e.g. Sharp Edges- commonly seen on the weld toes-, Peaks, Metal Inclusions- filler wire/metal/material inclusion-, dents, sudden variations or deviations in the weld dimensions...). ..You're gonna be able to see more of this requirements in the aerospace industry.

What is an angle shaft?
An angle shaft is an enriched angle bead, with a capital, base, or both.
What is the difference between u bead and j bead pool liners?
Basically, the "hole" it's going into. For example, the J bead is shaped to fit into the coping that is shaped to fit a J bead. J bead is different from a regular bead. A regular bead's coping does kinda looks like a sideways U. The difference in the beads is courtesy of the manufacturers. Some just had to be different. J bead and U beads go over the wall.No coping. There are some beads called Universal beads that fit into a groove in the coping or overlap the wall. Typical above ground beading is a K bead
Why is short bead in welding on mild steel and high tensile steel are to be avoided?
Short bead as well as arc strikes create a sudden localized temperature increase to the metal and can cause cracking.
Which is thicker 18 gauge or 12 gauge metal needles for bead craft?
The 12-gauge is thicker.
What height should bead board wainscoting be?
a kitty cat
