There are a number of different types of welding. The most popular are MIG, TIG and Stick welding. Each one of these processes has their own benefits and limitations, you just need to find out which one is best suited for the job in hand. Generally speaking, TIG is more suitable for clean, intrictate welds where appearance is paramount ahead of efficiency. MIG is a much easier process but the results aren’t quite to the same standard as TIG.
