What is meant by oxidation during welding?
When the molten metal of the weld pool reacts with the oxygen in the air. Typically, in arc welding a shielding gas is used. Usually argon as it does not react because it's a halogen. If welding iron or steel, oxidation causes the build up of iron oxide which is rust.
What is meant by the term welding and draw various welding symbols?
Welding is the process of joining two metals, usually involving a heat source. Welding symbols are the symbols used on part prints or assembly drawings to show size and type of weld, the specific welding process, and many other variables pertaining to that particular weld. A welding symbol looks like an arrow pointing to the location of the weld, with a horizontal line 'carrying' other symbols and numbers that describe how to make that weld. A picture of a welding symbol can be found when an image search is done.

Difference between homogeneous and homogeneous?
"Homogeneous" refers to something that is uniform or consistent in nature, while "homogeneous" means that all components of a mixture are evenly distributed. Both terms describe uniformity but in different contexts - one in terms of property, the other in terms of composition.
Is alchacol a heterogeneous or a homogeneous mixture?
Alcohol is a homogeneous pure compound not a mixture. Correct, unless you are discussing rubbing alcohol or an alcoholic beverage, which is a mixture of an alcohol (there are hundreds) and mostly water and other ingredients.
What is meant by trivial solution?
a trivial solution is one in which all the unknown are equal to zero.. Of course this only occurs in homogeneous equations
Is salt homogeneous or homogeneous?
