What welding techniques ensure durability in stainless steel outdoor trash can seams?
When manufacturing stainless steel outdoor trash cans, the durability of welded seams is critical for longevity and weather resistance. The most effective techniques include Tungsten Inert Gas (TIG) welding for its precision and clean finishes, and Metal Inert Gas (MIG) welding for efficiency on thicker sections. Both methods use argon-based shielding gas to prevent oxidation. Proper penetration without overheating preserves stainless steel's corrosion resistance. Post-weld treatments like pickling or passivation remove oxidation and restore protective chromium layers. Additionally, continuous welding without gaps prevents moisture intrusion. These techniques ensure seams withstand environmental stress, mechanical impacts, and corrosive elements, making them ideal for outdoor use.
