The process of fusing and cutting metals is one of preparation and danger, you get one thing wrong you’ll either have to start again or in worse case scenarios severe burns. The heat required for a piece of metal to melt is fairly high so welders need to create enough intensified heat and only in a small specific area, thankfully through the wonders of scientific advancement we’ve discovered that if you funnel flammable liquids from a pressurized container at high velocities you could create a fairly intensified flame that can cut through metal.

That’s how it used to work, nowadays we use electricity to heat the metal to a point where it melts from the contact of the electrified rod that sends an arc of electricity supplied from the arc welding machine. However, the process isn’t as simple as I described it, there are some nuanced processes and techniques one must observe before taking on the task of welding any form of metal. To start off you’ll need some safety equipment, with intense arcs comes intense light which could potentially blind you if your eyes aren’t protected, and that’s without the sparks that could fly into your face and damage your skin and eyes, so a welding mask is always necessary. This is also the case with an apron and gloves since you could get severe burns from the sparks or the hot metal you’ll be working with.


An arc welding machine uses an electrode to join two metal workpieces together using a flux covered electrode which is melted in an electric arc and becomes a fused part of the pieces being welded. A grounding wire needs to be attached to the metal you’re welding. Filler materials are also needed for welding materials together. The electrode also creates a protective gas which protects the weld while you’re applying the filler material. You’ll also have to have fairly steady hands when applying the filler material, since you’ll have to feed the filler into the joint using small, steady, back and forth motions. These motions are what gives welds their distinctive appearance, going too fast or too slow would create poor welds. You’ll also need to chip and brush the weld between passes, each time you complete a pass or trip from one end to the other of your weld, you’ll need to remove the slag to make a clean weld that won’t become corroded or rust afterward.
