It is perhaps easiest to make a blanket statement that practically everything we touch is metal or has been produced or transported on equipment made from welded metal. To illustrate:

Imagine what it would be like to live in a world without welding or metal objects. You would wake up in the morning without an alarm because electricity would not be available without a wire. If you got up before sunrise, you would need a candle for light. You would not have running water because there would be no metal or plastic plumbing. Why no plastic? Plastic is a petroleum product, and we would not be able to drill or refine petroleum without metals. You would have to rely on a well or nearby lake or stream for water. You would probably use a clay pitcher or wood bucket to carry the water to your house. No indoor plumbing also means using an outhouse. Your home would probably be heated by a wood fire since an electric or gas/oil furnace would not exist without metal. In summer, you would have no air conditioning.

You would get dressed in clothes made from animal skins or natural fibers such as wool, cotton, or hemp woven by hand on a wood-framed loom. Synthetic fibers such as nylon, polyester, poly fleece, etc., would not exist without petroleum. Without modern production methods, which rely on metals, you might only have one set of clothes to wear. With no spandex or other elastics, fashions would be much different, to say the least.

Your breakfast would be either local fresh food (long-distance transportation on trucks or trains would not exist without metal), or food preserved by salting, pickling, or drying since you would not have a freezer (unless you had access to ice from a frozen body of water or a glacier) and no canned goods whatsoever (remember, no metals?).

You would eat your breakfast with wood or clay dishes and utensils or simply use your hands.

Your transportation to work or school would be either a pack animal (horse, donkey, camel, or sled dog team), a wood or skin-covered boat, or you would walk. Any bridges would be made from wood or stone…significant concrete structures require steel rebar for strength, and so would not exist in the form we recognize today.

All of this time, you would not have access to music, videos, or social media…because cell phones, TVs, and computers all require welded metals to exist.
