Ten heats with sulfur contents from to wt.% and a wide range in Creq/Nieq ratios were studied. Tensile properties of welds with both processes were related to alloy composition and solidification : J. Brooks, S. Goods, C. Robino. Tensile flow properties were determined at all the regions i.e. weld metal, base metal and HAZ of dissimilar weld joints.

• The properties of the creep tested weld was compared with post weld heat treatment (PWHT) before creep condition. • Results show a degradation of strength on the P91 steel side, while strengthening occurring on the austenitic LN stainless steel side, after creep.

This paper investigated mechanical and corrosion behaviour of austenitic weld metal grade L which deposited by SMA (Shielded Metal Arc) method with various ferrite content. Several tests such as tensile at room temperature, charpy impact V-notch and lateral expansion at cryogenic temperature °C were conducted to observe mechanical behaviour.

Electrochemical testings such as Cyclic Polarization. The main aim of this paper is to study the mechanical properties of the weld also the microstructure of the weld joints were analyzed. The effects of sensitization of gas tungsten arc (GTA) welded L stainless steel (SS) joints were observed.

L stainless steel was heated to – °C, soaked for –2 h, and was observed. Tensile strength and elongation of the weld joint are Mpa and %, respectively. The tensile strength and elongation after heat treatment are MPa and %, respectively, and the fracture position is transferred to the weld.

In some spot welding studies using austenitic stainless steel, it has been reported that weld core diameter and weld tensile strength increase up to a certain optimum value due to increased.

HLM process possesses moderate heat input and cooling rate. The HLM weld metal exhibited ferritic austenitic solidification mode and FN. The hardness of weld metal was higher in hybrid welding processes due to the higher ferrite content. HLM weld joint has higher yield strength, ultimate tensile strength and ductility compared to that of the other weld joints.

HLM welding process also permits. Dissimilar metal welding of austenitic (AISI )-ferritic (AISI ) stainless steel has been taken up to understand the influence of the welding process on microstructure and mechanical properties. tensile strength and creep properties of the welds that are related to the above-mentioned uses and areas of applicabili­ ty-Experimental Procedures The chemical compositions of com­ mercial steel plate and filler metals used are shown in Table 1, and those of experimental filler metals and their weld metals are listed in Tables 2 and 3.

Austenitic stainless steels are most preferred over other types of stainless steel families. Welding of stainless steel using friction welding is widely seen in the current scenario. Since the time consumed for friction welding is very less, metallurgical defects are almost reduced without pre- and postheat treatment.

The problems encountered in friction welding during joining of austenitic. welded by several welding processes including the arc welding processes, resistance welding, electron and laser beam welding, friction welding and brazing.

For any of these processes, joint surfaces and any filler metal must be clean. The coefficient of thermal expansion for the austenitic types is 50% greater than that of carbon steel and. The as-deposited metal, which shows a lower yield strength, a comparable ultimate tensile strength and a lower total elongation compared to the (solution-annealed) parent metal, is characterized by systematic variations in tensile properties across its thickness, with the highest strength and the lowest ductility in the weld.

Matching filler metal is typically required for complete joint penetration groove welds in tension. However, fillet welds loaded in shear seldom require matching filler metal. Depending on the type of weld joint and loading, lower filler metal strengths. HY is a high-tensile, high yield strength, low alloy was developed for use in naval applications, specifically the development of pressure hulls for the US nuclear submarine program and is still currently used in many naval applications.

It is valued for its strength to weight ratio. [citation needed]The "HY" steels are designed to possess a high yield strength (strength in. To solve these issues, Hertzman studied the effect of nitrogen on the microstructure and properties of austenitic stainless steel and observed that the nitrogen loss of weld pools was avoided by controlling the shielding gas nitrogen content in tungsten inert gas (TIG) welding.

However, nitrogen addition results in the presence of nitrides. A risk of martensite formation in the weld after dilution by the base metal and residual amounts of ferrite resulting in possible hot cracking.

The deposition of carbon steel or low-alloy steel filler metal on austenitic stainless steel can result in hard, brittle weld deposits. Hot cracking may occur because of.
