A Day in the Life of a Welder

Preparing To Weld: Pre-Work and Setup

The day of a welder usually begins simple enough. With most weld shops, parts come in on a contractual basis and if this is the case, the welder must be familiar with each part that needs to be welded.

If a welder isn't familiar with the parts he or she is welding, the welder's day may start with reviewing blueprints and looking at a completed part that shows the parts' measurements and the places that welds needs to be placed. The blueprints also show the different types of welds that are needed for each part. Some parts require a small spot weld, like a drop of glue. Other parts require longer welds, or beads. All of this information will be contained in the blueprints for each individual project.

After reviewing blueprints, reviewing a completed part, or simply remembering from previous work, the welder may be responsible for obtaining and using the correct gauge wiring, loading it into his/her welding machine, and properly setting the speed that the wire comes out of the welding gun. If this isn't done properly, you could "arc out," which is a term used when the welder has caused the wire to weld over the opening of the gun. Sometimes arcing out is easily fixable with a set of pliers, other times the nozzle will need to be replaced.

The Art of Welding: During and Post-Processing

Once everything has been taken care of on the pre-weld side of things, it's time to begin the work, which always requires a steady hand and patience. Many mechanical and human errors can occur during a weld including burning through parts if settings aren't correct or allowing air bubbles into the weld which makes the weld weak and unfit for use. A proper weld should be performed with what's called "oscillation", or a rolling movement of the wrist, and when it's done it should look like a row of nickels.

After welds are completed, it is generally the responsibility of someone other than the welder to do a quality check on the parts completed to make sure the welds are properly done. This could involve a visual inspection or even an inspection with a type of x-ray machine to check for air bubbles. Depending on the part, the weld shop, and the damage done (if any), a bad weld could be repaired, if it is bad enough, by simply breaking the welded part loose at the seams. Other times the part is a total loss and must be marked as damaged and scrapped.

Welding may appear to be as simple as holding a gun, pulling a trigger and holding a steady line, but taking into account the weight of certain wiring, the speed the wiring comes out, and the types of welds that need to be laid, welding turns into an art form that only the dedicated can perform consistently.
