Common welding pipe connection methods and specifications
Common welded pipe connection methods and specifications: A) Butt welding connection Butt welding connection is a connection method in which the ends of two welded pipes are connected by welding. The connection methods are divided into three types: full welding, short welding and head welding. 1. Fully soldered connection Full welding is a connection method in which the ends of two welded pipes are completely welded together. The standard requirement for full welding is that the height of the weld should not be lower than the surface of the base metal, and the quality of the weld should be ensured. In addition, attention should be paid to welding current and time control during the welding process to prevent excessive heat from causing the weld to be too long or welding slag to be mixed into the weld. 2. Short solder connection Short welding is a connection method in which only part of the ends of two welded pipes are welded. The length of the weld shall not be less than the speci...
