ESAB Knowledge Center

Since Oscar Kjellberg's invention of the covered welding electrode in 1904, ESAB has played an integral part in the discovery and development of more commonly accepted welding processes than any other company.

ESAB's Knowledge Center contains a vast amount of information for the welder, the engineer, the welding inspector and the project manager.

A Duty Cycle Reality Check

We hear a lot of talk when it comes to duty cycle, including a lot of misinformation about compact integrated inverters (the type with a built-in wire feeder) as not being true "industrial" welding machines. This article attempts to add clarity to the conversation and provide two critical reality checks.

The rated output or "size" of a welding machine is measured using amps, volts and duty cycle. Duty cycle is the amount of time it may be operated at a given output without exceeding the temperature limits of its components, and it is measured using a 10-minute cycle.

In our example, the welding machine has a duty cycle of 40% at when MIG welding at 285 amps/28 volts. It can weld continuously ...

Tips for welding thin materials

Q: We're an independent welding supply and distributor company. We frequently field an array of questions from our broad customer base. While we have straightforward answers for most questions, we seem to have difficulty finding common ground on the topic of welding thin materials. What are some best practices for welding thin materials that we can share with our customers?

A: Thin material manufacturing is a large part of industry in the U.S. This includes various shapes of tubing, angles, and flat sheets, typically 24 gauge up to about 3/16-inch thick and usually manufactured from stainless steel, carbon steel, galvanized, or aluminum.To determine the best welding process, shielding ...

Heat input and its effects on material properties

Q: How does heat input from welding affect the mechanical performance of welded joints? Do preheat and interpass temperature have any effect on them as well?

A: For many applications that involve thin plain carbon steel such as A36 or similar grades, these variables have minimal effect on the final welded joint. The variables become much more important when you are welding higher-strength or alloyed base materials, so we will focus on those applications.

To produce high-strength materials with good toughness properties, there are two types of material that have different mechanisms used in their manufacture: high-strength, low-alloy (HSLA) and thermo-mechanically controlled processed ...

Comparing Filler Metals for Manual and Robotic Welding Applications

Nino Mascalco, Rob Koltz, and Steve Sigler counsel a fabricator who wants to know which welding process and wire type will work for their variety of welding work.

Q: Our job shop manufactures various products; some parts we weld manually or robotically on a jig, others we custom-build and weld manually. We currently use gas metal arc welding (GMAW) to assemble all of our parts. Which is the best welding process or wire type for all variations of welding we do? How much of an effect does the wire or process have on overall speed and efficiency?A: With several options to choose from, what you will find is that you might require more than one process for the variety of work you are performing.Depending ...

Cladding of Ni-alloy UNS N08825 in Pressure Vessel Applications: Optimized Efficiency with a Complete Solution.

Cladding of Ni-alloy UNS N08825 in pressure vessel applications: optimized efficiency with a complete solution.

Strip overlay cladding of Ni-alloys is one of the most cost sensitive applications in pressure vessel fabrication. Compared with cladding of austenitic alloys, Ni-alloy cladding has a major effect on the cost of the vessel production. Performing Ni-alloy overlay cladding in a controlled manner is essential to meet cost targets and optimize efficiencies.The cladding consumables, the actual cladding procedure and the equipment used are critical process parameters for fabricators seeking success in this application. The following key factors affecting cost efficiency will be discussed:

The ...
