Most mound ceremonial centers are built near rivers and lakes. Mound builders lived in small communities of families led by elders. They made pilgrimages to the closest ceremonial centers to make offerings to their gods and to bury their loved ones. The ceremonial centers were built on timbers, often with a temple for sacrifices on top and crypts to bury the dead underneath.
There are many different factors that may determine welding sequence. Of course, a 1G weld is defined as a Flat (1) Groove (G) weld and the 1G is usually used when describing the position of welding any flat material such as bar, sheet, or plate. The thickness of the material may affect sequence.
TIG Welding (GTAW) is a process that uses the a non-consumable tungsten electrode to produce a weld with or without a filler material. The equipment is significantly different than MIG equipment and somewhat different than what is used for stick welding. That said, a welding machine with the right accessories can be fitted for TIG welding.
