Set airflow between 15-20 cubic feet per hour. This is a true walk-around tig machine. The filler metal has a lower melting point than the base metals being joined, so it can be melted and flowed into the joint without melting the base metals. Let me explain what I mean. What is custom metal fabrication and shaping? The name of a torch type is often derived . Luckily, Distortion is pretty much the same. This is to protect red-hot tungsten while it is cooling down and avoid oxidation. The brazing temperature must be above 450C (840F), but below the melting point of the base metals being joined. Lets take a closer look. This occurs through a process referred to as capillary action. Brazing can be used to join dissimilar metals, while welding cannot. The most common brazing processes are torch brazing and furnace brazing. Silicon bronze lacks the tensile strength required for dynamic, load bearing structures. Welding. If you're doing stainless you're gonna sugar it trying to tig braze it anyways so you might as well bond it with the base metal, just grab a small container of solar flux, it'll last you a lifetime.
