A welding mask protects your eyes against damage and lets you see what you're doing. Mask: Both arcs and torches produce more light than the human eye can safely stand.Every welder needs certain pieces of safety gear: Even shielding gas can be dangerous if your cylinder springs a leak. You need to always make sure your tanks are in good condition and replace them when they show signs of corrosion. A gas cylinder can contain many pounds of gas under high pressure just waiting to get out. The first thing to consider before you start welding is safety. They use a continuous feed electrode that puddles on the metal, and a cylinder of shielding gas to keep air away from the weld. MIG Welding: MIG Welders are among the most common pieces of equipment available today.Most arc welders also use some form of inert gas as a shielding layer. Arc Welding: Most modern welders use some form of arc welding where you pass a current from an electrode through the workpiece and use that to generate heat.It can be tricky to balance everything and requires a constant supply of gas, but it was the only option for many years. Gas from the two tanks mixes in a torch, and used with a welding rod to create welds. Oxy-Acetylene Welding: Invented in the nineteenth century, this form uses two cylinders of welding gas: One cylinder of oxygen and another cylinder of acetylene.All forms require a heat source and most also require some form of gas cylinder: Unlike brazing which uses molten brass to join two dissimilar materials, welding only works for joining the same metal. The term applies to several different techniques for joining materials. The idea is simple you heat your work pieces up to the point that they actually melt and flow together creating a very strong bond. When you have two pieces of metal that you want to join together, there's no better way to do it than by welding.
