Hybrid Laser-Arc Welding of Thick-Walled, Closed, Circumferential Pipe Welds

Nasim Bakir

The application of hybrid laser-arc welding (HLAW) for joining closed circumferential welds is a challenge due to the high risk of forming a defective overlap area with a shrinkage void or solidification cracks in the material thickness. A series of HLAW experiments were performed to understand the development of a faulty overlap area when closing the circumferential weld. Welding trials on flat specimens and pipe segments were supported by numerical analyses in which the thermomechanical behavior of the welds in the overlap area was investigated. Different process control strategies were tested, including variations in defocusing levels and the overlap length. The newly developed HLAW head, including laser optics with a motor-driven collimation system, made it possible to defocus the laser beam during welding without disturbing the stability of the welding process. High-level defocusing of the laser beam of more than 40 mm relative to the specimen surface with a resulting beam diam...

Thick-section austenitic stainless steels have widespread industrial applications, especially in nuclear power plants. The joining methods used in the nuclear industry are primarily based on arc welding processes. However, it has recently been shown that the Narrow Gap Laser Welding (NGLW) technique can be used to join materials with thicknesses that are well beyond the capabilities of single pass autogenous laser welding. The heat input for NGLW is much lower than that of arc welding, as are the expected levels of residual stress and distortion.The multi-pass laser welding technique, based on the narrow gap approach, is an emerging welding technology which can be applied to thick-section welds using a relatively low-power laser, but the process is more complicated than autogenous laser welding, since it is necessary to introduce filler wire to narrow gap weld configurations. Despite this complexity, the technique is very promising for improving the penetration capabilities of the l...

Laser welding with high power laser: The effect of joint configuration

Antti Salminen, Mikhail Sokolov

The use of high power lasers with wavelength around 1000 nm is growing fast. These lasers are compensating the conventional CO2 lasers in various new applications due to the fact that beam transfer with optical fiber provides various beneficial features to actual welding process and machinery used. These lasers are still not through studied in respect of their behavior in various cases of different joint configurations possible for keyhole welding. Occasionally the power density can be too high for welding of specific case. This study concentrates on behavior of keyhole process and effect of this to weld quality and properties in various joints and penetrations. The tests were carried out with stainless steels and S355 structural steel in case of bead on plate, butt joint and fillet joint welding. The quality of weld in various cases changed according to joint preparation and welding parameters. It was possible to reach acceptable quality in all cases. The quality and process perfor...

Overview of the exploration status of laser-arc hybrid welding processes

Paul Kah

Metal industries producing thick sections have shown increasing interest in laser-arc hybrid welding processes because of their clear advantages compared with the individual processes of autogenous laser welding and arc welding. One major benefit of laser-arc hybrid welding is that compared to autogenous laser, welding joints with larger gaps can be welded with acceptable quality. The laser-arc hybrid welding process has good potential to extend the field of applications of laser technology, and provide significant improvements in weld quality and process efficiency in manufacturing applications. The objective of this review is to present a set-up for laser-arc hybrid welding processes and introduce a methodical comparison of the chosen parameters. The research describes the principles, means and applications of different types of laser-arc hybrid welding processes. Based on a review of the current knowledge base, important areas for further research are also identified. The study u...

What does silicon do in welding? ›

As an added deoxidizer, silicon also provides good weld metal fluidity so that the filler metal wets into the toes of the weld for complete fusion and produces a smooth, flat weld bead.

Which welding process is done for welding glass? ›

In fusion welding, the edges of the glass pieces to be joined are heated until they melt. Once in a molten state, the pieces are pressed together, allowing them to fuse as they cool and solidify. This technique is commonly used in hand-blown glass artistry and some industrial applications.

Is glass welding possible? ›

Welding glass is accomplished by heating the glass through the glass transition, turning it into a thick, formable, liquid mass. Heating is usually done with a gas or oxy-gas torch, or a furnace, because the temperatures for melting glass are often quite high.

What is the main purpose of silicon? ›

The element silicon is used extensively as a semiconductor in solid-state devices in the computer and microelectronics industries. For this, hyperpure silicon is needed. The silicon is selectively doped with tiny amounts of boron, gallium, phosphorus or arsenic to control its electrical properties.

What does adding silicon to metal do? ›

In copper alloys, silicon adds extra fluidity to the metal, allowing it to flow better into casting molds. Copper alloys with silicon are more workable and have increased heat resistance and durability.

How to weld glass together at home? ›

Glass fusing at home or in a more industrial setting has the same basic principles. It is essentially heating two or more pieces of glass in a kiln so that they melt together. The temperatures required for melting glass are particularly high and range from 1400F/760C to 1500F/815C.

What is it called when you weld glass together? ›

Glass welding is most commonly used during the practice of 'glassblowing'. Glassblowing is a technique that involves inflating and manipulating hot, molten glass into shapes or bubbles using a blowpipe, also referred to as a blow tube.

Which glass is best for welding? ›

Welding green lenses and welding cobalt blue lenses are both options for protecting your eyes while torching or welding. However, they differ in their purposes and applications. Green lenses are the most common type of lenses used in welding safety glasses.

How thick is welding glass? ›

Clear Welding Glass is made of clear sheet glass and clear float glass with thickness of 1.8mm, 2mm and 3mm. Comparing to sheet glass, float glass with more even thickness, less striations, bubbles, stones and inclusions. Thus the float glass welding glass shows better formation of image.

The sheer complexity of the technique requires more practice and focus to master than other less-technical welding methods. TIG welding also results in some of the strongest and sturdiest welds in the industry.

What is the role of silicon in welding electrodes? ›

Silicon (Si) is the most common deoxidizing element; depending on the intended use, electrodes generally contain 0.45% to 1% of the alloy. In this percentage range, silicon exhibits very good deoxidizing ability. Increasing silicon will increase weld strength with only a small decrease in ductility and toughness.

What is the purpose of adding silicon to steel? ›

Silicon increases strength and hardness but to a lesser extent than manganese. It is one of the principal deoxidizers used in the making of steels to improve soundness, i.e. to be free from defects, decays or damages. Silicon is present in all steels to a certain extent.
