ORDER HERE! ORDER HERE! These welding procedures were put together for: […]
In our previous post, we introduced the basics of weldng austenitic stainless steels (304, 304L, 316, and 316L). Now, let’s dive deeper into the metallurgy of these alloys. Understanding their composition and grain structure is crucial for achieving sound, high-quality welds. This knowledge empowers welding professionals to make informed decisions about welding processes, filler metals, […]
Austenitic stainless steels are a cornerstone of many industries because of their exceptional corrosion resistance, strength, and aesthetic appeal. The most commonly used austenitic stainless steels are grades 304, 304L, 316, and 316L. This article, the first in a series, will provide an essential overview of these materials, highlighting their unique characteristics and why proper […]
Metallurgy should matter to all of those involved in welding. Welding is a fascinating process. We take two pieces of metal, heat them up, and fuse them together, creating a single, solid piece. But what’s really happening to the base metal when we weld it with an electric arc, such as that used in GMAW […]
Weld design is a critical aspect of any structural or mechanical project, encompassing the selection of appropriate weld joints, sizing, filler metals, and ensuring both safety and cost-effectiveness. However, before we delve into the specifics of weld design, we must first understand its predecessor: element design. What is Element Design? Element design is the initial […]
When a weld fails in the field, the consequences can be catastrophic. Our experience as welding engineering consultants has shown us that such failures often expose deeper issues within a company’s welding operations. These situations can lead to fears of additional failures in other products or structures, potential harm or fatalities, litigation, and even bankruptcy. […]
Rework is extremely costly, especially in welding. If you consider what happens when a weld is rejected it is essentially triples the amount of work. You weld, you remove the weld, you reweld. On top of this it may require additional inspection. So, reducing rework can save considerable amounts of time and money.
Developing welding procedures requires an understanding of all the different essential variables as well as the process of qualifying or prequalifying such procedures.
Selecting the filler metal should not be a trivial matter. The easy way out is to select a filler metal that has matching strength, meaning that the minimum specified tensile strength of the filler metal matches that of the base metal. However, this is not always the best option. In some cases it may be beneficial to use undermatching filler metals. There are many factors to consider when selecting the right filler metal. Understanding requirements in the areas of strength, ductility, wear resistance, corrosion resistance, in-service demands, cost and productivity is essential.
