What is a face of a weld?
in reference to the acutal weld metal-it is the "bead", what you see on top.
The rate at which weld metal si added to the weld is known as the?
deposition rate
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.

Can you weld nonferrous metal?
yes
How do you calculate weld deposit metal weight?
At first, the area of cross section of the weld, length of the weld, volume of the weld in cubic inches, weight of weld in cubic inches. To express in formula: Weight of Weld Metal = _ Êx ÊBase Êx ÊHeight Êx ÊLength Êx ÊWeight of Material.
What is the height of a weld above the base metal in a groove weld called?
a crown

What is a Autogenous weld joint?
It is a weld made by melting the edges of the materials to be joined, but adding no filler metal to the weld.

Why do welds crack?
It is usually not the weld but the metal right beside the the weld. If a piece of metal needs to be welded, it may be getting thin in other places and when it is welded, the heat from the weld can weaken the metal and in some cases cause the metal to crystallize and be more brittle than it was.
What is weld pool?
A small "pool" of molten metal that is manipulated to crate a weld bead.
What glue do you use for metal on metal?
I use J B Weld or Araldite for metal to metal.
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 are the causes of slag inclusion?
Slag inclusions are nonmetallic solid material entrapped in weld metal or between weld metal and base metal. Slag inclusions are regions within the weld cross section or at the weld surface where the once-molten flux used to protect the molten metal is mechanically trapped within the solidified metal. This solidified slag represents a portion of the weld's cross-section where the metal is not fused to itself. This can result in a weakened condition which could impair the serviceability of the component. Inclusions may also appear at the weld surface. Like incomplete fusion, slag inclusions can occur between the weld and base metal or between individual weld passes. In fact, slag inclusions are often associated with incomplete fusion. Daniel
