There are several different goals that people might have in mind whenever they are trying to take part in welding. You might be interested in creating a weld that is as flexible as possible, and some people much prefer to look into creating welds that are completely free from scorch marks at this current point in time. However, most of the time people will be really interested in creating the strongest possible weld without a shadow of a doubt.
Unless you work in the automotive industry, suffice it to say that you would want to look through the different types of welding until you come upon the best one from a strength and durability point of view. As a result of the fact that this is the case, we would strongly recommend TIG welding as your method of choice. This form of welding is famous for being able to deposit the highest quantities of metal per hour out of any other welding technique that you could possibly have managed to learn the first thing about, and that is something that needs to be factored into your future decisions regarding what you want to end up specializing in.
While TIG welding might not be quite as refined or precise as MIG welding, its durability has made it a mainstay of the industry. If you want to create a weld that would never come apart but would instead allow you to fuse the metal pieces together so much so that they become one and the same, TIG welding is your best bet although it is a highly technical form of welding that usually requires a lot more time to be able to learn.
