Resistance vs. MIG/TIG Welding

Completing a successful metal stamping project not only includes bending and forming metal sheets into your desired shapes, but also using precise welding skills to fuse and combine those pieces into a cohesive and functional design. In the realm of metal fabrication and welding, two techniques stand out as standard processes for joining critical components and fashioning a completed metal stamped project.

Resistance Welding

Resistance welding is a standard welding process used to merge materials together by passing an electrical current and generating enough heat to fuse the interfaces into a cohesive line. Resistance welding also incorporates different processes for different applications. For example, spot welding may be used to join overlapping metal sheets while seam welding is more suitable for creating long continuous welds along the seams of two pieces of material.

MIG/TIG Welding

Metal inert gas (MIG) and tungsten inert gas (TIG) welding are processes that rely on using an electrode and shielding gas to create welds. The main difference between these two processes is that MIG welding utilizes a consumable wire electrode whereas TIG welding relies on a non-consumable wire electrode. These processes are most used for specialized welding projects that require higher levels of intricacy or control.

MIG/TIG welds are generally considered to be superior processes for complex projects that require high-quality and sustainable welds. For this reason, these processes are commonly used in major industries such as automotive and aerospace. However, resistance welding, while considered less ideal for high levels of quality or precision, is a much more time and cost-effective welding solution. Resistance welding is commonly used for high-volume production and versatile applications.

Partnering with an experienced metal stamping supplier well-versed in different welds and applications can be extremely beneficial. This expert guidance can help guide you to identify the best welding processes for your unique project, considering the complexity of your design, your material selection, and your budget.
