What is the disadvantage of without preheating in welding?
Preheating can assist the welding penetration on materials with high thermal conductivity such as thick aluminum sections or even some steels. This reduces the heat sink affect (rapid cooling) of the deposited weld by the surrounding cold metal. Preheating also significantly reduces the rapid cooldown of the item post welding. Contrary to many beliefs, it is difficult if not impossible to overheat metals but many metals (such as carbon steels) can become brittle if cooled rapidly. They can also lock in post weld stresses that can compromise the engineering qualities expected. Preheating builds up heat in the metal and it takes longer for it to cool. In affect, preheating is also a portion of the postheating formula. In most welding code applications, carbon steels and some other metals require preheating prior to welding to be in compliance.
Why must you always preheat an oven before using it it?
Preheating an oven will cause whatevr your baking to cook evenly
Why is preheating necessary when baking?
Preheating is necessary because it ensures that the oven is at the temperature that you want it to be when you start cooking. If you do not preheat, you will probably end up with undercooked food, because you did not actually cook it at the right temperature for the right amount of time.
Why plastic pellet preheating?
To reduce moisture level present in the pellets ,this reduces the problems like fish marks in processing.
Why should an oven be preheated when cooking pastry?
Most cooking times are worked out for a preheated oven. This is because different ovens may have different heating up periods because of varying insulation or element sizes. For recipes to be consistent for any possible oven, they cannot take all the possible variations for preheating into account, and therefore require that the oven is already at temperature before cooking starts.When you are familiar with how long your oven takes to heat up you can experiment with the oven not fully heated before using, but note that this will not work with some recipes that require a quick change of heat.If not preheating, set the timer for at least an extra 2 minutes. Ovens vary in cooking time even after preheating.Check the recipe before cooking. Sometimes preheating is, and sometimes preheating is not, necessary.If you need to cook something in the oven for a specific amount of time at a specific temperature, then it must be cooked at that temperature the WHOLE time. If it takes 10 minutes to preheat it to 300 degrees, and you put the food in WITHOUT preheating, you undercook it, and if you out the food in WHILE preheating, you end up overcooking it.

What is the purpose of engine preheating?
The purpose of preheating your engine is to get all of the fluids in your car running smoothly, especially during the winter. If a car is not preheated, if it is cold enough, your engine could perform less optimally, or in rare cases stall. However, contrary to popular belief, most modern cars only need about a minute or less to preheat during the winter.
What is preheating in welding?
welding cast iron is not reccomended although it can be done,myself i have always had the best luck by preheating the cast iron to almost cherry red then using a low hydrogen electrode such as 7018 which is fairly common,there is also an electrode known as inconel which contains the alloy nickel,but its hard to find and very expensive
