With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
Bead-on-plate welding of AISI 304 stainless steel plates with 5 kW continuous wave (CW) fiber laser was performed with different nitrogen and argon mixtures.
This series of stainless steel is suitable for both pulsed and continuous wave (CW) laser welding. Laser welding stainless steel provides slightly better weld penetration depths and increased weld speeds when compared to low carbon steels due to the lower thermal conductivity of most austenitic stainless steels.

Many may choose 303 because of its free machining characteristics, but its high carbon content (0.15 percent) and high levels of sulfur cause problems for laser welding. A better choice might be 304, 314L, or a 316 stainless. In stainless material, such as the 304 and 316 series, the chromium-nickel ratio generally should exceed 1.7.
Laser Hybrid Welding of Stainless Steel At Stainless Structurals we have several methods of production to produce the stainless steel sections required for your project. Our proprietary laser fusion method is what separates us from our competitors and this same technology has allowed us to develop our own laser hybrid welding method for many ss 304 laser welding
Austenitic stainless steels (304, 316, etc) and carbon steels love autogenous laser welding. No filler metal is required for strength or corrosion concerns. Sheets can be seamed together without any edge preparation with full weld penetration from one side.
Pulsed Laser Welding of 304 and 316 Stainless Steels Austenitic stainless steels find extensive use in practically every industry due to their ductility, non-magnetic properties, corrosion resistance, and ability to be used at cryogenic temperatures. The most common austenitic stainless steel is 304 SS and makes
304 is much easier to laser weld since the melt has some ferrite content which has much greater solubility for impurities and avoids cracking. A mixture of 304 and 316 should be free from cracking. In case your experiments do indicate some level of cracks, you can try biasing the laser spot towards 304.
Melting Point 2800 2550-2650 Type 304 requires less heat to produce fusion, which means faster F Approx. welding for the same heat or less heat input for the same speed. Electrical Resistance This is of importance in electric fusion methods.

I tig weld many different stainless alloys together and I can't tell the difference. I welded 316 to 304, 316 to 17-4ph, 304 to 17-4ph. I didn't notice any reduction in corrosion resistance, in practical use. For things that I use in seawater, I usually clean up the weld with a deburring wheel followed by polishing the part. Max

WELDING OF STAINLESS STEELS 1.0 INTRODUCTION Stainless steels are defined as iron base alloys which contain at least 10.5% chromium. The thin but dense chromium oxide film which forms on the surface of a stainless steel provides corrosion resistance and prevents further oxidation. There are five types of stainless steels depending on the other ss 304 laser welding
The development of nonrusting stainless steels with distinct attributes that include varying degrees of corrosion resistance, strength, and workability has been a tremendous benefit to steel users. This development, however, also has made welding stainless steel more complicated than welding traditional carbon steel.
Laser Beam Welding of 304 Stainless Steel to Zinc Coated Steel Top bead of lap weld of 304 stainless steel and zinc coated steel. The ability to create products using different metals and alloys greatly increases design and production flexibility.
Stationary gas tungsten arc and laser beam welds were made on two heats of Type 304 austenitic stainless steels containing 90 ppm sulfur and 240 ppm sulfur. A transient heat transfer model was utilized to simulate the heat flow and fluid flow in the weld pool.
Laser welding of AISI 304 stainless steel was carried out by pulsed Nd:YAG laser machine under different welding conditions. Geometrical shape of the joints was circular butt. Studies were focused on laser power, welding velocity, beam diameter and pulse duration.
This is why many manufacturers are careful to use specialized metal alloys such as stainless steel for a variety of different applications. However, while laymen are generally familiar with the term stainless steel, many are not familiar with the fact that there are many different types of stainless steel, such as grade 301 SS or grade 304 SS.
Due to its versatile applications, Laser welding is becoming very popular when it comes to stainless steel welding. OR Laser offers highly efficient stainless steel welding machines that can replace traditional welding techniques such as high frequency resistance, ultrasonic beam, submerged arc, RF induction and many others.
The technique to weld AISI 304 stainless steel to AISI 420 stainless steel with a pulsed Nd:YAG laser has been investigated. The main objective of this study was to determine the influence of the laser beam position, with respect to the joint, on weld characteristics.
Laser beam welding is generally thought to not be a good welding process for joining copper to stainless steel. However, lasers have advanced in the last few years to the point where good results are regularly obtained. The primary limitation with laser beam welding stems from the fact that copper is highly reflective to laser beam light.
In generall 308L or 309L are the two preferred filler metals for 304L to most any other austenitic stainless steel. 308L was designed specifically for the purposes of joining austenitic stainless steel and as welding-consultant mentioned has a higher ferrite content compared to 304 or 316L 316 could be used but it's more expensive with no advantage, so it's not worth it in my opinion
The morphology, microstructure, microhardness, tensile properties and corrosion resistance of the SLMed 304 stainless steel and their laser-welded joints under various welding types are investigated. The main conclusions are as follows: (1) The stress-relieved SLMed 304 stainless steel shows a good laser weldability without obvious defects.

Welding will actually soften a zone in 301 full hard stainless 304 stainless is by far the most commonly used stainless steel, especially in the food and beverage industry and is typically welded with 308L rod. Stainless steel requires shielding gas coverage if you are making a full penetration weld where the back side of the weld is molten.

This particular stainless steel alloy was chosen as the structural material because it is easy to machine and weld . By join-ing NiTi to a structural material, the difculties and cost asso-
In the future laser welding will also play a key role when it comes to producing high-quality profiles. Today laser welded profiles in stainless steel are already preferred over cheaper, hot rolled alternatives due to quality reasons.
Laser beam welding (LBW) is a welding technique used to join pieces of metal or thermoplastics through the use of a laser.The beam provides a concentrated heat source, allowing for narrow, deep welds and high welding rates.
