Heat produced by an arc can be lost before it reaches the weld through radiation to the surrounding air, conduction through the electrode and base metal, and dissipation through the welding equipment and workpiece. Some heat is also lost through spatter, slag formation, and other heat-affected zones in the weld area.
What else can I help you with?
Heat that can't be used to do work?
You may be going for the concept of entropy (H, Greek upper case eta). It's not that entropic heat is of no 'particular' use. Before the heat flowed to where it is now entropy, it might have been used to do work of some kind. The potential to do work that this heat once had cannot be retrieved. The heat can be collected again, but at a substantial energy cost; perhaps too high a cost to make it practical. The previously lost potential to do work is lost forever.
What form of energy is always produced when energy changes from one form to another?
Heat energy is always produced when energy changes from one form to another. This is due to the inherent inefficiencies in energy conversion processes, where some of the energy is lost as heat.
When energy transformations occur what energy is always produced?
When energy transformations occur, heat energy is always produced as a byproduct. This is due to the second law of thermodynamics, which states that some amount of usable energy is always lost to heat in any energy transformation process.
What is always produce during energy transformation?
Heat is always produced during energy transformations. This is because not all of the energy input can be converted to useful work, and some of it is lost in the form of heat due to inefficiencies in the conversion process.
Where is most energy lost in a power station?
In a power station, most energy is lost as waste heat during the conversion of fuel into electricity. This waste heat is produced during various processes, including combustion, heat transfer, and friction in the machinery. Efforts to improve energy efficiency in power stations aim to minimize this waste heat and increase the overall efficiency of the system.
In the food chain how much of the Sun's energy is lost as heat before it reaches a producer?
About 90% of the Sun's energy is lost as heat before it reaches a producer in the food chain. This loss occurs through processes such as reflection, absorption, and transmission in the Earth's atmosphere.
What are disadvantages of heat produced by friction in machines?
energy used for the machine will get lost as heat .machine parts will get worn out.
How much heat loss from muscle be an advantage for to humans rather than a disadvantage?
For heat loss to be an advantage to humans rather than a disadvantage, the heat lost must be equal to that produced.

Yes, he lost to the Miami Heat
What type of energy is produced when objects become hotter?
The flow of heat energy is classifyed under the subject of Enthalphy, and all heat lost or gained is measured in Joules (J).
What form of energy is always produced when energy changes from one form to another?
Heat energy is always produced when energy changes from one form to another. This is due to the inherent inefficiencies in energy conversion processes, where some of the energy is lost as heat.
What percent of radiation is lost before reaching Earth suface?
25% is absorbed by clouds.25% is reflected by clouds.So 50% of the sun's radiation is lost before it reaches earth's surface.See the diagram link below.

Where is body heat produced?
Body heat is produced within your cells. For one, when you exercise the chemical energy used in the muscles contracting is not efficiently turned into mechanical energy and the excess is lost as heat. The various metabolic reactions occurring withing your body also produce heat such as the breakdown of chemicals within your cells. There really is no one place where body heat is produced. Hope this helps!
