They make leather ap[rons for welding, you can find them at any welding supply store. If, on the off chance that you are talking about cold soldering, then you don't really need any PPE (Personal Protective Equipment) Some gloves might save you the discomfort of touching a hot pipe, but other than that normal clothing is fine.

Absolutely not , Ships had no piping as everything was either rowing or sail, There was no such thing as hydraulics or fire suppression systems. There was only public o…ut houses that had 23,765 adjoining toilets BUT no sinks as there was no bamboo in America or England Plumbing came after WW 2 when they took the old guns and canons and made them to carry waste and water
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.
Wouldn't that depend on the type of plumbing your doing? If I am welding I would wear my welders mask and my welding clothes to prevent myself from being… burnt by hot slag or X rays given off by the arc If I am doing sewer and drain cleaning I would not wear loose fitting clothes as it could get tangled in the sewer cables If I am working JOBBING then CLEAN uniforms are in order, If I am working new construction or alterations then coverall's are the dress of the day with a loop for my striker
When the molten metal of the weld pool reacts with the oxygen in the air. Typically, in arc welding a shielding gas is used. Usually argon as it does not react because it's a …halogen. If welding iron or steel, oxidation causes the build up of iron oxide which is rust.
Because while welding it emits a very, very, very bright light that can burn your retinas, besides who doesn't look badass while wearing one :D
only if you are looking to damage your eyes and get wicked sunburn to the rest of your face
Welding helmet which has eye protection and a face shield .

The current flows through the electrode and to the clamp. That's how it flows in MIG, stick, flux cored. On Tig, the electricity flows through the electrode also except that n…ow that's the only function of it, the rod is held in your hand and electrode in the other.
Basically to prevent the weld and metal from cooling down too quickly which can damage or destroy it.
The primary purpose of flux is "to clean". It mixes with the elements in the molten puddle and removes impurities. As it cools it floats to the surface and creates the slag wh…ich prevents Oxygen from attacking the Iron.

It is extremely important to wear goggles when welding in order to prevent any damage to the eyes. Flying pieces of molten metal, chemicals or acids could blind or cause serio…us damage.
One would wear a welding mask or welding helmet during a welding job. This is a must to protect one_«_s eyes and prevent face burns. This is also a stipulated by the Labor …Department. One can also wear them during Halloween or Carnival.
