Welding is an important process and has a very important part in industry, especially in the automotive, maritime, and energy sectors. Although welding has many advantages, it also has some disadvantages such as thermal expansion and shrinkage or microstructural transformations, which cause stresses. All these processes have a main influence on the distortion during and after welding. With knowing all these properties and welding parameters, it’s possible to predict the final distortion. Accurate prediction of the distortion is important when distortion on some unique, large parts has to be predicted. To achieve the deformation in the desirable limits, changes in welding parameters can be made, such as welding sequence and clamping of the welded parts. When changing some welding parameters of complex parts, with a large number of beads or multipass welding, etc., it’s not easy to predict the distortion after welding (Refs. 1, 2). When the welding procedure is planned, it’s now possi...

Cryogenics can be defined as the science and technology of temperatures below –153°C (120 K). This limiting temperature was proposed based upon the boiling point of the main atmosphere gases, as well as methane, which are below this temperature (Ref. 1). According to Lebrun (Ref. 2), cryogenics arose two centuries ago from the search to liquefy the atmospheric gases considered until that time incondensable. In 1877, L. Cailletet and R. Pictet liquefied air for the first time, and in 1883, K. Olszewski and S. Wroblewski separated oxygen from nitrogen. However, the increase in cryogenics applications started in 1908, when H. Kamrelingh Onnes made the first helium liquefaction. There is also equipment in the chemical and petrochemical industries that work in temperatures as low as –100°C, which is not exactly a cryogenic application according to the definition presented above. In both cases (cryogenics or low-temperature applications), the 300 stainless steels series is widely used, an...

An evaluation of the cross-tension test behavior of resistance spot welds in high-strength dual-phase steels was performed with two objectives. The first objective was to examine the variables that affect the load-carrying capacity of spot welds in 780 and 980 MPa dualphase steels. This was accomplished through cross-tension testing of the steels, and finite element modeling (FEM) of the weld crosstension test behavior. The second objective was to determine whether the cross-tension test represents the type of loading and deformation modes that spot welds undergo in a real vehicle crash event. This was done through a detailed examination of a crash-tested vehicle made available for examination by the Auto/Steel Partnership of the American Iron and Steel Institute. The observed weld failure modes and base material deformation in the crash-tested vehicle were compared to those in the cross-tension test. The modeling indicated that the failure load in the cross-tension test is related ...

The residual δ-ferrite that remains at room temperature once a stainless steel has been welded, that is, after it has experienced the process of melting followed by solidification, will determine the material’s properties and behavior during its service lifetime. It is well known that primary ferritic solidification avoids the hot cracking phenomenon in austenitic stainless steels, but the determination of the solidification mode requires a metallographic analysis, which is a destructive test. Therefore, in practical terms, a minimum δ-ferrite content of 3–4 FN (Ferrite Number) is considered an acceptable indicator to ensure the absence of hot cracking during solidification. However, for specific applications or service conditions, it is necessary to impose a maximum δ-ferrite content; for example, for hightemperature conditions or thermal cycles (350°–900°C) when δ-ferrite can suffer from spinodal decomposition or be transformed into (σ) sigma-phase, causing embrittlement and a dec...

FAQs

What is the impact factor of AWS Welding Journal? ›

Welding Journal Research Supplement Archive

Research papers must be submitted through Editorial Manager, where you will find more information on submission guidelines and author responsibilities. The Welding Journal Impact Factor (JIF) for 2022 is 2.2.

What is the easiest welding position? ›

Flat Welding Position

Also known as the downhand position, the flat position is the easiest of all the welding positions. A flat position is the common type of weld. It is the first weld that beginners learn. In this position, you are not welding against gravity.

What is the 6G position in welding? ›

6G Welding Position: One of the most challenging welding positions, 6G is similar to 5G, but the pipe is positioned at 45° to the other. The 6G position requires three welds: horizontal, flat, and vertical.

What does 2F mean in welding? ›

To help operators understand the type of weld joint (fillet or groove) and the weld position, each weld is given a number and a letter — 1G, 2G, 3G, 4G or 1F, 2F, 3F, 4F — to indicate the position and the type of weld required. Welds with a 1 are flat position, 2 is horizontal, 3 is vertical and 4 is overhead.

What is the acceptable impact factor of a journal? ›

In general, an impact factor of 10 or higher is considered remarkable, while 3 is good, and the average score is less than 1. The very prestigious journal Nature had an impact factor of 69.504 in the year 2021. ➡️ Learn more: What is a good h-index?

What is the number 1 rule in welding? ›

1. Ensure the cleaning of the material and place to be welded. Before starting any welding procedure, make sure that everything is free of impurities. Contamination damages the final result.

What position is hardest in welding? ›

Mastering the most difficult welding positions, which includes the overhead or 6G positions, isn't just about talent—it's a testament to a welder's dedication. It speaks to the heart of American values—morals, circle of relatives, work ethic, and self-reliance.

What is the highest paid welding position? ›

The highest paying welder jobs are in industrial construction. Pipe welders, tube welders, rig welders, underwater welders and combo welders are the highest paid of all welding jobs. The type of welding is important and so is the industry. The top welder salary can be over $200,000 per year in industrial construction.

What is the hardest welding test? ›

The 6G Pipe Welding Certification is the most difficult welding test to pass. This certification tests a welder's skill in all positions of pipe welding, including overhead, vertical, and horizontal.

What is a 5G weld? ›

In the 5G position, the pipe is fixed at one or both ends and the welding operator must travel in one of two directions, either vertical-up or vertical-down. Depending on the location of the pipe, the application may also require welding either overhead or in a flat position.

Why is it called arc welding? ›

Mechanism of arc welding

When the voltage applied to two spatially separated electrodes is gradually increased, the air insulation finally breaks and current flows between the electrodes, emitting bright light and high heat at the same time. The generated arc-shaped light is called an electric arc or arc.

What does Z mean in welding symbols? ›

z = leg length. s = penetration throat thickness. For butt joints and welds, an S with a number to the left of a symbol refers to the depth of penetration as shown in Fig.

What does F mean in welding code? ›

Filler Metals: The F Number

This number is used to group filler metals used in welding procedures and welder performance qualifications.

Is it better to weld vertical up or down? ›

While both methods have their advantages and disadvantages, uphill is generally preferred for its higher quality and better penetration, especially in thicker materials. However, downhill is faster and can be used for thinner materials.

What is the impact factor of welding? ›

The Welding Journal Impact Factor (JIF) for 2023 is 2.2.

How do I find the impact factor of IEEE journals? ›

Click on a publication title in the search results to access important data about that publication including Aims & Scope, bibliometric scores such as the Impact Factor, open access availability, the average time from submission to online publication, and more.

What is impact factor in WOS? ›

What is Journal Impact Factor? The resulting number represents the average number of citations to an average recent article in the journal. Note that not all journals have an Impact Factor since Impact Factor can only be calculated for journals included in Web of Science.
