A 'weld-done' finish - The Fabricator

  • Restoring The Hairline FinishThe Mirror FinishMaximizing Finishing EfficiencyGetting Around Corner WeldsWhen a hairline finish must be restored, use an elastic flap disk to remove the weld. One type of abrasive disk that does this is made from a compound developed specifically for grinding stainless steel. The fiber in the compound is derived from the hemp plant, which provides excellent abrasion while also being environmentally friendly. Heat absorbency is another characteristic of this material. When this type of abrasive flap disk is used on a variable-speed angle grinder at a maximum of 8,000 RPM, the grindinFiber Laser Welding of 100 Micron Stainless Steel SPI LasersFiber Laser Welding of 100 Micron Stainless Steel. Fiber Lasers are penetrating the precision Laser welding market. Precision welded parts in the medical or computer industry require very high quality but relatively low penetration welds, typically less than 0.1 mm thick. The average power required to weld this thickness of material for small medical components is relatively low, mostly less than 50 watts. How to weld Duplex Stainless Steel.ppt [Read-Only]Duplex Stainless Steel Welding methods Laser, laser hybrid and plasma welding Are all high productivity methods. On a whole, S/S do not require preheat. Welding takes place at room temperature At low temperatures a maximum of 50°C preheat is advisable to drive off any moisture.

    • Laser Implementation BasicsChoosing MaterialChoosing Joint GeometryChoosing A Laser ProcessChoosing The Tooling and WorkstationSimulation, Verification, and CommunicationMonitoring and SupportMost laser processes weld autogenously, meaning without filler metal, with a minimal heat-affected zone (HAZ) and just enough heat to melt and fuse the material. This produces a high-quality weld joint with minimal thermal distortion. But welding autogenously does require intimate contact between the mating surfaces. Because the laser is a highly concentrated heat source, the joint generallymelts, fuses, and cools extremely quickly. This means the process must work with material that can endure quick cooling Rapid Cooling of Laser Welds in Stainless SteelA previous article in this newsletter entitled Laser Welding Austenitic (300 Series) Stainless Steel introduced the effects of composition and microstructure on the tendency for laser welds in austenitic stainless steels to crack. The article also noted:Cooling rates associated with laser welding, which are generally high with respect to other welding processes, also influence the
