Welding is a process by which metal is joined to metal, using another molten material as a joiner. There are several different ways that this can be accomplished, each way better suited to different purposes. For those of you who know nothing about welding equipment, machinery and supplies, this is the article for you. We will look at a few basic terms, tools and processes related to this industry.

Arc welding is probably the most common, and simplest, type of welding. This process fuses metals together by creating an electrical current at the end of a welding rod; the current creates a high temperature, capable of melting metal. Alternating current arc welders are available just about anywhere for very little money. These tools are sufficient for the week-end welder or someone who just likes to have tools “just in case”. Basic welding is not difficult, but there are some safety issues that should be addressed before beginning any project; shock, burns, eye-damage and flying sparks are all potential risks. However, with the proper supplies (goggles, apron, rubber soled shoes and gloves), welding can be done safely and quickly.

Commercial welding equipment, machinery and supplies are different than those for the general public. Most industrial welding is done using an oxyacetylene torch. These machines are capable of reaching temperatures of up to 6000 degrees F., which is not often necessary for the week-end welder; they also require more experience than an arc welder, so if you have never used this type of machine, be sure to do your homework first.
