Stainless Steel Welding Characteristics By definition, stainless steels are iron-base alloys containing 10% or more chromium, which imparts to the metal the corrosion-resistant properties for which stainless steels are so highly regarded. The chromium content may be increased and other alloying elements added or adjusted to meet specific end-

Jun 02, 2020Since the year 1913, when Harry Brearley introduced stainless steel (SS) to the metal industry, metallurgists from around the world have experimented with unique combinations of SS alloys to evolve the SS grades to be the most sturdy, malleable, and corrosion-resistant metals as they are today. Due to its extreme temperature tolerance and bacteria-proof nature, (plate) FAQ 5 Galling and its Control(steel) Austenitic stainless steels are widely used for corrosion resistant bolting. One of the major problems in use is that diassembly is difficult because nuts and bolts seize.

Explanation of Typical Passivation ProceduresExplanation with Regard to Pem FastenersApplicable Industry SpecificationsPassivation is the generic term applied to procedures developed to remove the presence of metallic (free) iron from the surface of stainless steel products. The presence of free iron particles on the surface of stainless steel products can cause the product to show rust spots which should not occur with a clean or passive stainless steel surface. A PASSIVE stainless steel surface would have NO free iron particles which could potentially corrode or rust. During See more on pemnetNon Destructive Testing - Radiographic Testing (RT)(steel) History of Radiographic TestingWhat Is Radiographic Testing?StandardsThe history of radiographic testing actually involves two beginnings. The first commenced with the discovery of x-Rays by Wilhelm Conrad Röntgen in 1895 and the second with the announcement by Marie Curie, in December of 1898, that the demonstrated the existence of a new radioactive material called "Radium". More about Curie and Röntgen can be found on the World Wide Web.See more on wermacFAQ 1 Galvanic/Dissimilar Metal Corrosion(steel) Stainless steel has an effective passive film so the available corrosion current able to be carried by charged atoms (ions) is quite low. If the behaviour of a copper/steel and a stainless steel/steel couple is compared, the copper/steel coupling is a more significant galvanic problem despite the similar potential separation of 0.35 volts.(plate) People also askWhat is Rt welding?What is Rt welding?RT usually is suitable for testing welded joints that can be accessed from both sides, with the exception of double-wall signal image techniques used on some pipe. Although this is a slow and expensive NDT method, it is a dependable way to detect porosity, inclusions, cracks, and voids in weld interiors.Non Destructive Testing - Radiographic Testing (RT)
Resistance welding is a process by where current and pressure are used to bond two pieces of metal. Resistance welding requires force in the bonding process. Pressure is used to hold two pieces of metal together while they are cooling. This also allows for the metals to properly bond together. The necessary pressure for the bonding process is typically applied by the machine (plate) Projection Welding of Fasteners to Hot Stamped Boron (steel) for the welding of fasteners.
