Welding Processes for Stainless Steel
Below we discuss the most popular welding processes used for
Metal Inert Gas (MIG) Welding/Gas Metal Arc Welding (GMAW)
MIG welding, or gas metal arc welding as it is more formally known,
is one of the more popular ways to weld stainless steel. There are
many similarities between MIG welding stainless steel and welding
carbon steel. No special drive rolls need to be used, and the
electrical polarity remains the same. However, shielding gas
compositions are typically different. Lower amounts of oxygen are
allowable when welding stainless steel, so O2 or CO2 levels should
be kept around 2% or lower. It is quite common for tri-blend
shielding gases that contain argon, helium, and carbon dioxide or
oxygen to be used when MIG welding stainless steel. Since corrosion
resistance will typically be desired in the weld as well as the
base material, stainless steel welding wire must be used.
Furthermore, to prevent cracking, the filler wire and base
stainless steel should be a low carbon version or have stabilizers
in them such as tantalum or niobium. Using a pulsed welding
waveform can also help users MIG weld stainless steel more
Tungsten Inert Gas (TIG) Welding/Gas Tungsten Arc Welding (GTAW)
TIG welding, more formally known as gas tungsten arc welding, is
another process that is frequently used to weld stainless steel.
This process also has similarities between when it is used to weld
carbon steel and when it is used to weld stainless steel. Both
materials require a direct current electrode negative (DCEN)
polarity. Typically, nearly 100% argon or helium shielding gases
are used. As with MIG welding, TIG welding requires stainless steel
filler metal to prevent making a weld that will be easily
susceptible to corrosion. Low carbon or stabilized grades of
stainless steel should be used as filler metals, and the base
metals should also be low carbon or stabilized. Distortion can be a
major problem when welding stainless steel, so it is important to
keep travel speeds somewhat fast and heat inputs low when TIG
welding stainless steel.
Flux-Cored Arc Welding
In general, welding processes that use flux are not optimal for
welding stainless steel. That being said, it is possible to weld
stainless steel with the flux-cored process. Special gas mixtures
need to be used. Gas-shielded flux-cored arc welding is typically a
better choice of process to weld stainless steel than flux-cored
arc welding since it relies less on flux than the latter process to
shield the weld metal from the atmosphere.
Metal-Cored Arc Welding
A better cored wire alternative to both self-shielded flux-cored
arc welding and gas-shielded flux-cored arc welding is metal-cored
arc welding. This is mostly because metal-cored arc welding does
not rely on flux at all. The metal core of the filler material,
while it does have certain kinds of deoxidizers, is mostly packed
with powdered metals to increase deposition. With the proper
shielding gas and wire feeding system, metal-cored arc welding can
be used to make high-quality welds on stainless steel. For the most
part, a pulsed waveform or spray-transfer arc is required to make a
high-quality stainless steel weld with metal-cored arc welding.
Laser Beam Welding (LBW)
Laser beam welding is frequently used to join together stainless
steel at very fast travel speeds and with very low heat inputs.
Care must be taken to avoid porosity and cracking when welding with
lasers. Cracks and porosity can be avoided through reducing the
amount of oxygen via a shielding gas and weld parameter
optimization. Laser beam welding is never performed manually, and
therefore, must be automated if it is selected as the process to be
used for welding stainless steel.
Other Welding Processes Used on Stainless Steel
The above-mentioned processes are perhaps the most common processes
used to weld stainless steel. There are many other, somewhat less
popular processes out in the industry that can be used to weld
stainless steel. They include plasma arc welding (PAW), electron
beam welding (EBW), shielded metal arc welding (SMAW), friction stir welding (FSW), and resistance welding (RW).
This list is not exhaustive, and there are many more welding
processes that can weld stainless steel together with varying
levels of success.
CNC milling, or computer numerical control milling, is a machining
process which employs computerized controls and rotating
multi-point cutting tools to progressively remove material from the
workpiece and produce a custom-designed part or product. This
process is suitable for machining a wide range of materials, such
as metal, plastic, glass, and wood, and producing a variety of custom-designed parts
Several capabilities are offered under the umbrella of precision CNC machining services, including mechanical, chemical, electrical, and thermal
processes. CNC milling is a mechanical machining process along with
drilling, turning, and a variety of other machining processes,
meaning that material is removed from the workpiece via mechanical
means, such as the actions of the milling machine’s cutting tools.
This article focuses on the CNC milling process, outlining the
basics of the process, and the components and tooling of the CNC
milling machine. Additionally, this article explores the various
milling operations and provides alternatives to the CNC milling
