Fundamentals of Cutting Technologies To compare laser cutting and plasma cutting effectively, it’s essential to understand the core mechanics behind each method. While both are thermal cutting processes designed to shape and separate metal, they operate using different technologies and physical principles. Principles of Laser Cutting Laser cutting uses a concentrated beam of light to […]

Summary Laser welding has become a leading method for joining stainless steel thanks to its precision, low heat input, and suitability for automation. When set up correctly, it delivers deep penetration, minimal distortion, and clean welds that preserve stainless steel’s corrosion resistance. Successful results depend on more than just laser power—material preparation, joint design, shielding […]

Defects: Causes and Fixes Laser welding stainless steel offers unmatched precision, but defects can still occur when material preparation, process parameters, or shielding gas delivery are not fully optimized. Unlike arc welding, laser welding’s small molten pool solidifies extremely quickly, so even minor disruptions in energy delivery or shielding can produce visible or hidden flaws. […]

Distortion, Residual Stress, And Fixturing Laser welding’s concentrated heat input significantly reduces distortion compared to MIG or TIG welding, but stainless steel’s thermal expansion rate (~17 µm/m·℃) is still almost 1.5× that of carbon steel. This means even small temperature changes can cause measurable movement. Residual stresses form when the weld metal and surrounding base metal […]

Heat Input, Cooling Rate, And Metallurgical Control Laser welding is inherently a low heat input, high cooling rate process, which is one reason it’s so effective for stainless steel. But “low heat” is not automatically “good” — the wrong heat input or cooling profile can lead to incomplete fusion, excessive ferrite, or microstructural defects that […]

Laser Welding Fundamentals Understanding the fundamentals of laser welding is essential to produce strong, consistent welds in stainless steel. The process relies on tightly controlled parameters that determine penetration depth, weld width, and heat-affected zone size. The following concepts define how a laser interacts with stainless steel and how different settings influence results. Conduction VS. […]

Why Laser-Weld Stainless Steel? Laser welding offers several advantages that make it one of the most effective methods for joining stainless steel. Its unique combination of speed, precision, and minimal thermal impact delivers results that are difficult to achieve with conventional welding methods. Low distortion and minimal heat tint: Stainless steel is sensitive to heat, […]
