What You Will Do

• Contact a welding organisation that represents the welding industry in your country or region to find out the types of welding jobs, the qualifications and/or skills required and the industries or areas where there are likely to be growing needs for welding professionals and related job positions in the future.
• Find out which guidelines for welding technical drawings are used most often by contacting an organisation or association that represents the welding industry where you live.
• Look for two or three examples of welds that show colours in the weld. Determine what the metals are and whether there is any corrosion.
• Visit a supplier of welding equipment. Ask someone to show you the accessories that they have that can be used specifically with your chosen type of welding.
• Choose a type of welding and visit a welding accessories supplier. Find out electrodes suitable for this type of welding, the classification codes on these electrodes, and their uses.
• Visit a hardware store or manufacturer of metals for fabrication. Find out the types of metals they provide which are suitable for welding. Focus on any coating, relevant dimensions, and cost.
• Obtain access to welding equipment and practice doing one string bead and three different patterns of weave bead.
• Interview someone who has practical experience with arc welding and ask them to explain how to create two different fillet welds and two different butt (groove) welds and ways of avoiding defects.
• Make a comparison chart for the different metal fabrication techniques used in your industry or an industry of you are interested in.

Welding is the process of joining two or more pieces of metal together using a combination of heat and pressure.

Welding, like cutting, is one of the most common metal fabrication techniques. Parts employed in a welding application can be sheets, panels, bars, or shapes, so long as they are a metal. Welding can be done with a variety of procedures and tools. The application of heat along the points where the two pieces are designed to be linked is frequently used to create a weld. Many metalworkers begin their careers in metal fabrication by pursuing welding tasks.

This course is more than just welding though. It will also teach you about other techniques used for working with metals, including punching, stamping, shearing, cutting, casting, forging, machining and more.
