Welding Stainless Steel to Carbon Steel
Welding of austenitic stainless steel and carbon steel base metal should use a filler metal that prevents solidification cracking. 309 is the preferred filler metal as it provides ferrite number of at least 3.

5 Common Mistakes Made Welding Stainless Steel
Most types of stainless steels have good weldability and can be welded with all arc welding processes (GMAW, FCAW, GTAW, SMAW and SAW). Stainless is used in many different applications for its strength, abrasion resistance and corrosion resistance. Unfortunately, many assume it can be welded just like carbon steel. In fact, this is the first […]
How to Avoid Sensitization When Welding Austenitic Stainless Steels
Stainless steels are iron based alloys that contain a minimum of 10.5% chromium. This chromium reacts with the air and forms a very thin but very tenacious chromium oxide layer which is what prevents stainless from rusting. There are 5 types of stainless steels which are categorized depending on additional alloying elements. One thing they […]
