Getting the perfect stainless steel TIG welds may require some practice, but you can set yourself up for success with the right products and some essential knowledge about the process. Start by selecting the correct welding rod for your material thickness and composition, and once you have the right supplies for the job, you can begin perfecting your application by managing your speed, and purging the backside of your welds. Let’s review these steps in more detail.
The thicker the welding rod, the more heat is required to melt it, so the diameter of the filler metal should be thinner than your base metal. Your goal is to use a wire thin enough to apply a smooth bead that combats lumps, but still be thick enough to build up and control.
The filler metal and base metal should also be mechanically and chemically compatible to ensure strong welds and longevity. While there is some room for variation in your selection, base metals are traditionally specified for use with one filler metal. 316L base metal, for an example, will call for 316L filler metal, while 304 base metal will call for 308L filler metal. In short, the strength of your welds must meet or exceed the strength of your base metal to prevent cracking, snapping, or separation due to poor bonding. Choosing a compatible filler helps safeguard that durability.
