A Comparative Study on Nd:YAG Laser Cutting of Steel and

Jun 01, 2012 · Laser cutting with the sine waveform is seldom reported. This article is a comparative study on Nd:YAG laser cutting using the continuous (CW), square, and sine waveforms. The materials used in this study were steel and stainless steel. It has been found that the cutting capability, in descending order, is:CW > sine > square. The cutting of steel (C ~0.3 wt.%) and AISI304 austenitic stainless A Comparative Study on Nd:YAG Laser Cutting of Steel and Jun 25, 2011 · Laser cutting with the sine waveform is seldom reported. This article is a comparative study on Nd:YAG laser cutting using the continuous (CW), square, and sine waveforms. The materials used in this study were steel and stainless steel.

ANALYSIS OF THE HEAT AFFECTED ZONE IN CO2 LASER

laser nitrogen cutting of stainless steel. Four main laser cutting pa-rameters such as the laser power, cutting speed, assist gas pressure and focus position were considered. A mathematical model for the analysis of the width of HAZ was developed using the artificial neural network (ANN) on the basis of experimental results. The laser cutting ex- Endurance lasers start to make new diode-pumped YAG May 15, 2020 · Endurance lasers start to make new diode-pumped YAG INDUSTRIAL lasers with an output power of 75W-200W CW . The key function is to cut 2-3 mm aluminum, steel, stainless steel, copper, and brass. A portable laser head metalwork. Key parameters:Type:. Call +7 (916) 225-43-02. Laser Cutting:Steel and AluminumOct 20, 2018 · Nd:YAG lasers are usually incapable of cutting steel at any thickness around 20 millimeters or higher, but can be paired with an optical fiber enhancement and an oxygen assist gas mechanism to enable them to cut thicker steel material.

Laser Hybrid Welding of A Lean Duplex Stainless Steel

Kuwana, T. (1996) Effect of nitrogen on corrosion of duplex stainless steel weld metal, Science and Technology of Welding and Joining 3, 225-232. [22] Khan, P.A.A., DebRoy, T. & David, S.A. (1988) Laser beam welding of high-manganese stainless steelsexamination of alloying element loss and microstructural changes, Welding Journal 67, 1s-7s. Laser Marking Stainless Steel Hai Tech LasersThe main method of laser marking stainless steel at Hai Tech Lasers, Inc. is:Stain marking. This method involves heating the surface of the object to form an oxide layer. Both the thickness of the oxide layer and the grade of stainless steel affect the color that appears. Benefits of Laser Marking Stainless Steel Laser Metal Cutting Machines Laser Cutters Boss LaserYAG or crystal laser technology has been used in the past primarily for thick metal cutting, but it is more expensive and offers a significantly shorter service life compared to CO 2 and fiber laser processing. The majority of sheet metal cutting applications - especially under 6mm -

Underwater cutting technology of thick stainless steel

Mar 01, 2003 · In nuclear power plants, irradiated materials like Control Rod (CR) should be stored underwater after service. Due to reducing the storage space, underwater cutting technology is expected. In this study, we developed underwater cutting technology of thick stainless steel with YAG laser in order to cut used CR. Preliminary tests were performed with flat plate test-pieces to optimize the cutting Underwater cutting technology of thick stainless steel We also investigated the wastes like dross and aerosols by laser cutting. Amount of dross was approximately 0.1 kg/m after cutting a 14 mm thick stainless steel plate, which is estimated to be less than other cutting method. Based on these results, we developed underwater cutting system of CR test-piece with YAG laser as a mock-up test.Studies on pulsed Nd:YAG laser cutting of thick stainless Aug 01, 2015 · For pulsed Nd:YAG laser cutting of thick section steel, millisecond (ms) duration pulses are preferable, since thermal time constant for thick sheet of stainless steel is of the order of tens of ms for a given power density of 10 5 W/cm 2. Clearly, long pulse Nd:YAG laser treatment provides an effective means for cutting during dismantling of thick steel structures.
