How to weld dissimilar metals

Welding engineers know how crucial the right filler metal is, especially when joining dissimilar metals. It’s not just about welding two pieces together and getting them to hold; it’s about creating a welded connection that can withstand the intended service conditions. In the case of stainless steel and other nickel alloys we also want corrosion […]

How to Use Prequalified WPSs for Stainless Steel in Accordance with AWS D1.6

AWS D1.6 is the Structural Welding Code for Stainless Steel.  Its primary concern is with the structural integrity of weldments and not with resistance to corrosion, creep or sensitization.  As a matter of fact, the word “corrosion” appears only eight times in the 9 clauses of AWS D1.6.  Requirements for these concerns are the responsibility […]

Why demand for aluminum welding is increasing

The ability to develop welding procedures for aluminum and aluminum alloys coupled with the ability to weld these alloys is becoming even more important for fabricators. Whether it is a job shop producing different products every day or a firm that specializes in a single product, the ability to fabricate out of aluminum is necessary. […]

How to Weld Weathering (CORTEN) Steel

Corten, or COR-TEN, is the trademark name for weathering steels manufactured by U.S. Steel Corporation.  Weathering steels are a family of low carbon steel alloys that were specifically developed to provide higher strength and more importantly eliminate the need to paint to protect against the elements (rain, snow, humidity, sun, salt, etc.). A242 and A588 […]
