The welding process requires workers to join metal parts by melting metal pieces and forging them together. According to the Bureau of Labor statistics, welders have good employment opportunities, although there will not be rapid growth within this field. You must receive training prior to working as a welder. Training is available at community colleges, technical schools and in high-schools. Preparing to work as a welder takes as little as six weeks and most welders earn a starting wage of $13 to $18 per hour.
Blueprint reading is a hands-on course that allows students to learn and interpret the welding symbols and assembly drawings included in most blueprints used in industrial environments. By learning to read blueprints, welders are able to identify the width, height and length dimensions of a project, interpret welding and other symbols and sketch objects that accurately depict the details.
Welders must be comfortable with geometry and fractions. They must also know how to compute simple formulas and take accurate measurements. These skills are essential since welders must be precise in order to avoid costly mistakes. Welders frequently use the same mathematical formulas, which makes it easy for new welders to catch on quickly.
Chemistry and Physics
Welding is a skill that basic engineering principles are applied to, so you must know the basics of chemistry and physics. Chemistry and physics are sciences that study energy and matter and the effects of them interacting with each other. Welding is the joining of two metals together by heating them, so there is a chemical and physical reaction occurring. By learning basic chemistry and physics, you will gain a broader understanding of what is happening when metals heat up and bind together.
Welding involves preparing metals, checking them for rust, using the proper safety gear and melting the metal pieces together. Welders must know the difference between a good weld and a bad one. They must know how to listen to the metals closely during the welding process since this is how they will know if the metals are welding properly. Welders must also know how to listen intently to their welding apparatus. This is another way to gauge how the welding process is going.
