Miller Multimatic 215


For those who are not familiar with welding, there are three main arc welding processes: TIG, or tungsten inert gas; MIG, or metal inert gas; and shielded metal arc welding, or stick welding. Arc welding creates welded joints by using an electric arc to melt the work materials along with the filler material, or welding rod. A grounding wire is attached to the welding material or another metal surface, and an electrode lead is placed on the material to be welded. An arc is generated when the lead is pulled away from the material, and this arc is used to join the filler and workpieces by melting them together.

A welder must have a steady hand, as the filler needs to be fed into the joint with a continuous and small back-and-forth motion. This gives welds their appearance. Rushing the weld or even welding too slowly can create poor welds.

TIG, MIG, and Stick Welding

TIG, MIG, and stick welding each have their own advantages and pitfalls. For example, TIG welding is difficult to master and requires an elaborate welding system, but it produces high-quality welds that couldn’t be created with other methods. Stick welding, on the other hand, is easy to learn and inexpensive; however, it is less versatile than the other methods and is a slower process.

Safety Hazards of Welding

Welders should take caution because welding can be a dangerous and unhealthy practice if you do not proceed with proper care. However, the risk of injury associated with welding has been greatly reduced by the use of new technology.

It still should be noted that the open electric arc poses a burn risk from the heat and sparks. When welding, you should use protective clothing such as long-sleeved jackets and heavy leather gloves to avoid exposure. Additionally, the use of compressed gases in tandem with flames and electric arcs could potentially cause an explosion. You should thus limit the oxygen in the air and keep work materials separate from combustibles.

Causes of Welding

Eye damage is also a concern of welders, as the brightness of the electric arc can lead to a condition aptly named arc eye. This is caused by ultraviolet light inflaming the eye’s cornea and burning the retina. For protection, welders use protective devices like welding goggles and helmets with shaded faceplates. Recent technology has also produced welding helmets with faceplates that electronically darken automatically. Welding curtains made of polyvinyl chloride plastic film usually surround the welding area in order to protect others in the vicinity, as well. These curtains shield nearby workers from UV light from the electrical arc.

Gases that are used in or result from welding are not only explosive, but they are also toxic. Flux-cored arc welding and shielded metal arc welding produce smoke that contains particles of various oxides. Welders are exposed to particulate matter, as well, so proper ventilation is vital in welding workspaces.

Certain welding systems can also produce a high frequency that has been found to interfere with pacemaker operation if the pacemaker is within six feet of the power unit or within three feet of the weld site.
