What is a welding training? so, first of all if you undergo welding training it means that you want to be a welder, so what does a welder do? Here are some basic ideas on what a welder do from day to day, a welder specifically joins pieces of metal with metal filler, using heat or pressure, welders also join parts being manufactured, they build structures and repair broken or cracked part, according to specifications. So now that we know what a welder does, we’ll then proceed to welding training, basically all I know about this is that welding training helps plant maintenance workers develop a working knowledge of and learn the theory behind gas and arc welding techniques and heavy equipment operation, also the cutting of iron, steel, pipe, and nonferrous metals. That is what a welder literally trains for I guess, aside from the more advanced stuff. So I conclude that being a welder requires a lot of patience and hard work, as it is not an easy job, and that welding training is tiring but would pay off once you finish it.
