There are many different types of NDT, but the most common are visual inspection, radiography, ultrasonic, and magnetic particle testing. This procedure isnt suited for structural applications because it is designed for thin sheet metal, approximately 1 to 2 mm thickness, in lower strength alloys such as 3004 and 5052. There are many different types of weld tests, each with its own objective & testing requirements. %%EOF 0000081679 00000 n But be careful here. Resistance welding (RW) is a thermo-electric welding process in which the weld is made by a combination of pressure and current. thats very critical! It is important that the notch is present only in the weld deposit and that the cutting tool (abrasive disc, hacksaw, etc.) An SWPS must meet the rules for qualification of AWS B2.1, Specification for Welding Procedure and Performance Qualification, and be approved by the AWS B2 Committee on Procedure and Performance Qualification. The hardness of the base metal and weld-metal of a welded joint is affected by chemical composition, the metallurgical effects of welding, cold working of the metal, heat treatment, and several other factors. There are many different types of weld tests (destructive Tests & Non-Destructive Tests) as explained in this post, each with its own objectives. does not touch the plate surface. The most common application of MPT is in the welding industry. I appreciate all of the info that you guys have provided me.
