Stainless steel is a material solution used in a wide variety of applications because of its inherent corrosion resistance, high temperature oxidation resistance, and strength. Joining separate stainless steel pieces via a high power welding process is preferred over other methods of welding or adhesion in many automotive, medical, and military and aerospace (MIL/AERO) applications because of laser welded joints offer the highest strength and a variety of other benefits. These include:
Stainless steel is described according to the material property of each type. These are the laser welding considerations and requirements for each.
Note on grades and making final choices: Because of the variety of stainless steel types/grades, Accumet encourages process testing before finalizing a design. Also, the use of free-machining grades should be avoided because these stainless steels contain sulfur that can lead to hot cracking during laser welding.
Accumet is a full-service processed materials provider offering laser and machining solutions. Our machines are of the highest caliber and include features such as optical alignment, rotary welding, different power outputs, and the capability to be fixtured to accommodate various shapes and sizes.
Optical alignment offers many benefits, including the ability to line up to an existing weld and repair it, for example. Rotary welding allows for welding both inside and outside stainless steel tubes, and even allows us to weld a tube within a tube. Different power outputs allow for the welding of varying types and thicknesses of materials, which also allows for spot welds and continuous welds, dictated by the materials being welded, as well as the size of the weld. Varying machines allow us to achieve any combinations of power, focus diameter of a beam, pulsed energy, pulse duration, and pulse frequency, amongst other parameters, as specified by your project's unique requirements. We also offer a one-stop experience for all of your laser cutting, production and assembly needs.
