A butt weld is the most common for pipe to pipe connections. Depending on the size, pipe fittings normally are butt welds or socket welds. Smaller connections (2 and smaller more or less) can be socket weld (fillet) or butt welds. Larger than 2 (more or less) are typically butt weld. For flanges, in addition to butt weld and socketweld, slip on flanges are also available. They usually require two fillet welds one on the inside and the other on the outside.
