Welding Stainless Steel
Process Date: January 2003
The photo on the left shows a cross-sectional view of two 0.037" stainless steel tabs that were butt-welded using an Evolution 240W CO2 laser. After welding, the tab was cut perpendicular to the weld and cleaned up with an abrasive pad. The photo clearly illustrates the complete penetration achieved during the weld; the welded section is virtually indistinguishable from the rest of the tab.
The weld was made using 240W at a speed of 16 inches per minute (IPM) with argon as a shield gas. No filler wire was used, or was required, in the laser welding process.
Butt-weld of 0.037" stainless steel. The welds were made with a Synrad Evolution 240W laser.
