Are spot welding and resistance welding the same?

Spot welding (also known as resistance spot welding) is a resistance welding process. This welding process is used primarily for welding two or more metal sheets together by applying pressure and heat from an electric current to the weld area.

Is TIG welding resistance welding?

TIG welding, also known as gas tungsten arc welding (GTAW), is an arc welding process that uses a non-consumable electrode made of tungsten to run an electrical current through metal. The metal’s resistance to this current causes it to heat up, allowing it to bond with other materials by melting into them.

What is resistance spot welding used for?

Another material that is able to be joined by resistance spot welding is copper and its alloys. However, spot welding copper cannot be simply accomplished with the traditional copper-alloy spot welding electrode because the heat created in the electrodes and the work piece are way too alike.

What is the difference between resistance spot welding and resistance seam welding?

Resistance Seam Welding is a subset of Resistance Spot Welding using wheel-shaped electrodes to deliver force and welding current to the parts. The difference is that the workpiece rolls between the wheel-shaped electrodes while weld current is applied.

Which welding is not a type of resistance welding?

Carbon arc welding is not a type of resistance welding. It is a type of electric arc welding.

What is difference between spot welding and seam welding?

A seam weld is a continuous weld along a joint. Unlike a spot weld that uses a single point electrode, a seam weld uses a rotating wheel electrode that produces a rolling resistance weld. This process is most often used to join two sheets of metal. MIG and TIG welders can be used to do seam welding.

What type of welding is resistance welding?

Resistance welding is a fusion welding process that requires the application of both heat and pressure to achieve a sound joint. The simplest form of the process is spot welding where the pressure is provided by clamping two or more overlapping sheets between two electrodes (Fig. 9.1).
