An example of a non-polymer would be water (H2O), which is a small molecule made of two different types of atoms (hydrogen and oxygen) that are not linked together in a repeating chain like in a polymer.
The two types of bonds seen in polymers are covalent bonds, which are strong chemical bonds formed between atoms within the polymer chain, and non-covalent bonds, which are weaker interactions like hydrogen bonds or van der Waals forces between polymer chains.
Yes, glue is a polymer.
When water is added to a polymer, it can cause the polymer chains to swell and increase in volume. This is because water molecules can interact with the polymer chains, promoting their separation and expansion. In some cases, this can lead to the polymer absorbing water and becoming softer or more flexible.
The general term for very large molecules is "macromolecules". There are special terms for different specific types of macromolecules, like "polymers" or "proteins", and most people studying them specialize in one or another specific type.
Double submerged arc welded pipes has two types, one is spiral welded pipes, and the other is longitudinal welded pipes which are different from EFW pipes.
YES. Seeing gold can be melted it can be welded also. As welding is the melting of two types of similar metals to be joined to make one. I bet it is more common to braze or solder it.
Various types of steel is in modern damascus such as O1,1084, etc forge welded together.

It is called aluminum welding. Aluminum can be TIG welded, the most common method, or oxy-fuel welded, or stick welded, or MIG welded.
Bags are commonly made of polyethylene, which is a polymer composed of repeating ethylene monomer units. Polyethylene is a versatile and widely used polymer due to its low cost, flexibility, and resistance to moisture and chemicals. It can be found in various types of bags, including grocery bags, trash bags, and packaging materials.

L- SAW stands for Longitudinal Sub Merged Arc Welded Pipe.here the pipe are produced by welding a plate longitudinaly. i.e the welded seam will be longitudinal. these types of pipes are basicaly used for non critical lines.
Pipes that have been welded (or melted) together.
A properly designed disposal site is usually lined with a tiled gravel layer to collect any leachate and prevent the buildup of groundwater, then a compacted clay liner, then a welded impervious polypropylene (or other polymer) liner. A final earth liner is then added to protect the polymer liner from mechaniacal damage during use.
