Welding joints, techniques and expertise are applied to countless industries, from automotive and aeronautical, to manufacturing and shipping. Welders are required to have versatile knowledge about the different types of welds and how to perform them, even when the welding required is not as comfortab...
Welds between metallic materials having sharply differing chemical, thermophysical, and mechanical characteristics are widely used in many fields of engineering. A reasonable combination of the characteristic features and properties associated with each of the materials employed, allowing for the specific ...
The electrochemical behavior and oxide film structure of the weld of 316L/52M/A508 dissimilar metal welded joints were investigated via scanning electron microscopy (SEM), potentiodynamic polarization measurements, electrochemical impedance spectroscopy (EIS), and X-ray photoelectron spectroscopy (XPS). The...
The influence of weld undercuts and bead flank angles on fatigue strength were experimentally investigated, using fillet welded joints. Non-load-carrying c... M Onozuka,Y Kumakura - 《Fillet Welds》 被引量: 2发表: 1993年 Fatigue behavior of load-carrying cruciform joints with partial penetration...
inspection on the weld. You imply this in the description of the weld neck flange, where you point out that radiographic examination is possible. Radiographic examination is generally possible on all butt welds and not possible on fillet welds – also not possible on nipoflanges and weldoflange...
theory and on-job for all the types of welding that would be used by the shipyard (usually, Arc welding, MIG Welding, TIG Welding, etc.) After completion of the training period, each welder is tested, and the quality of their welds are examined by non- destructive testing methods. Only...
1. It is made of stainless steel and treated by surface treatment. It is durable, bright as mirror, no rust and no change. 2, the use of micro-dot resistance welding and welding technology without the butt welding, so that the product has no protruding solder ...
Many studies have been performed concerning the hydrogen-assisted cracking, microstructure evolution, and fracture behaviors of these Cr–Mo steels and their welded joints in service environment for ensuring the reliability of reactors [1,2,3,4]. However, the severer operating environment and the ...
C and m coefficients of Paris–Erdogan equation for spot welded AISI 304–galvanized steel sheet joints were obtained. Introduction Resistance spot welds are crucial to the automotive industry since the typical car body contains about a thousands spot welds joining a mixture of metal material types ...
Many types of welding beads can be used for different welding processes, joints, and positions. Some of the most common types of welding beads are: Stringer beads:These are straight and narrow weld beads that are created by moving the torch or the electrode in a straight line along the join...
