Selecting Filler Metals for Stainless Steels

TIG Welding with Viking and Redline welding apparel

The capabilities that make stainless steel so attractive — the ability to tailor its mechanical properties and resistance to corrosion and oxidation — also increase the complexity of selecting an appropriate filler metal. Any of of several types of electrodes may be appropriate for any give base material combination, depending on cost issues, service conditions, desired mechanical properties, and a host of welding-related issues.

Grinder Selection Tips

Untitled

There’s rarely a day that a welder goes without using a right-angle grinder. It is common practice to use a right-angle grinder after welding a joint to remove a weld bead. A grinder is also usually used to create beveled edges on pipe joints and to prepare metal surfaces for other welding processes. It is accurate to say “where there is a welder, there is a grinder.” Therefore, having the right grinder is critical for the job.

When it comes to welding stainless steel tube and pipe, there’s no guesswork. Proper selection of filler metals, joint preparation, cleanliness and welding process help ensure the final product meets the designated quality standards and retains its intended corrosion-resistant qualities. However, there are evolutions to well-established processes and techniques that allow pipe fabricators to increase productivity without sacrificing the corrosion resistance of the stainless steel.

Brazed components play a crucial role in consistent joining techniques. The brazing process is characterized by low process temperatures and fast processing times, compared to welding techniques. Beside the resulting low manufacturing costs, brazing can join dissimilar materials, e.g. metals and ceramics. Consequently, brazing provides potential for many industrial applications like the production of power electronic devices, in automotive engineering, and for power generation. Simultaneously, brazing provides potentials for seminal applications, such as for the production of structures for particle accelerators and in space technology, as well as for heat exchanging systems for hydrogen energy production.

The beginning of the modern welding age started in the 19th century, and up to the present day there has been continuous advancements in the science and technology of the global welding industry. The evolution has naturally created a demand for more advanced welding quality standards, and therefore a coinciding evolution in welding inspection technology. Today, more inspection techniques, testing methods and non-destructive examination (NDE) equipment than ever before are being used by the welding industry to achieve weld quality insurance.

The American Welding Society (AWS) published the standards of weld quality and safety which is upheld by Certified Welding Inspectors (CWIs) and Certified Welding Educators (CWEs). It is important that CWIs and CWEs use the most advanced inspection equipment and visual inspection methods available in order to adhere to these crucial standards. Specialized cameras are used during the weld process and NDE equipment is utilized in order to achieve complete weld quality assurance.
