Essay On The Terminology Of Weld

Sections & Terminology of Welds

The figures below indicate section areas and terminology which need to be considered when the welded area is examined. Figure 1: retrieved from http://www.weldguru.com/SMAWNomenclatureandJoints.html

As it can be seen below the fusion zone is the position the position where the base metal is melted together and combined with the weld. Root of the weld is the area at the bottom of the specimen where the welding comes in contact with the surface of the base metal. The toe of the weld is the area at the top surface of the component where a junction between the base metal and the face of the weld has occurred. The reinforcement of the weld is the excessive weld metal on the top of the surface of the specimen on the face of the groove weld.

Moreover, several other instruments can be used from the operator for profile assessment of the inspected objects, such as mirrors and gauges. Last but not least, endoscopes and borescopes are used for inspecting parts with limited access.

Visual Testing applications

This method finds applications in virtually every industry and can be used for primary processing inspection, secondary process inspection and in-service inspection.

Primary process inspection is referring to the inspection of raw materials that are going to be used for the manufacturing process such as furnace conditions and ladle lining.

Secondary and finishing process includes the monitoring of components that are used for the forming of welding, extrusion, forging soldering and many others.

However, in this particular project in-service inspection needs to be taken into more consideration, because of the need to inspect components that are operating.

In-service
