What is downhill welding?
MY question is (WHAT IS DOWNHILL WELDING) The correct term is Down Hand Welding. Most welds in the vertical position are made from bottom to top. Down Hand means welding from the top to bottom. These welds are usually made on thin metal as the heat input is lower, thereby reducing penetration/burn thru.
Why is welding used?
When two pieces of metal are joined by welding they become one as if they were made that way. Welding replaced riveting and reduced the amount of metal used while producing a stronger joint.
What is a nelson stud?
A weld stud made by Nelson Stud Welding, Inc.
Do you need tools for welding?
Every welder ought to have many clamps! C-clamps, vice grips, wide mouth vice grips (snap clamps) and bar clamps; a nice dead blow (metal mallet covered in rubber,) wire brush to clean welding area before and after weld, good grinder to grind down a finished weld. Also setup blocks, but that's only in R&D and precision welding shops.
What element is used to make chains?
Usually some sort of metal, but the specific metal can vary. Many chains are made of steel, which is a mixture of iron and some other element, usually carbon.
What very large organic compound made up of chains of smaller molecules?
A very large organic compound made up of chains of smaller molecules is a polymer. Polymers are macromolecules formed by repeating units of smaller molecules called monomers. Examples of polymers include proteins, DNA, and synthetic plastics.
What is organic compounds made of long chains of smaller molecules joined together to make large molecules?
polymers
A very large organic molecule made up of chains of smaller molecules is called?
condensation
Long chains of sugars are?
Long chains of sugars are polysaccharides. These large molecules are made up of numerous monosaccharide units linked together through glycosidic bonds. Examples include starch, glycogen, and cellulose.
What is hydrogel made of?
Hydrogel is made of a network of polymer chains that can absorb and retain large amounts of water. These polymer chains are typically made from materials such as acrylic acid or acrylamide. The structure of hydrogels gives them unique properties, such as high water content and soft, gel-like consistency.
Are all polymers made of chains smaller molecules?
Yes. That is why they are called polymers. The prefix "poly-" means many. A polymer is made from many monomers.
What are Most welding tips made of?
copper
What is welding nozzle made from?
Copper and brass
Why is a welding machine not adjusted when a welder is welding?
two reasons i can think of: 1 - Probably dont need to, usually welding material of constant thickness. 2 - The transformer is mechanically adjusted on most welders, this means that that there would be a possibility for electricity jumping in the transformer, and premature failure, or fire.
Proteins are made of chains of?
chains of 20 basic amino acids
What is a large molecule made of nucleotides?
A large molecule made of nucleotides is called DNA (deoxyribonucleic acid) or RNA (ribonucleic acid). These nucleic acids contain long chains of nucleotides, which are the building blocks of genetic information in living organisms.
Is a food web made up many food chains?
no a food web is made up of many food chains
