Resistance welding, also known as electric resistance welding, is a welding process that utilizes electric current and pressure application to join two or more metal pieces. For its speed and accuracy, resistance welding is widely adopted in many industries.
Resistance welding has four common techniques—spot welding, projection welding, seam welding, and butt welding.
During the spot welding process, high heat is produced while the pressure is applied to join specific spots together. Spot welding is commonly applied in automotive, electric vehicle (EV), aerospace, rail, manufacturing, electronics and construction, etc.
The projection welding process is characterized by using projections to concentrate current and pressure. Projection welding is suitable for thicker components and also used for joining thin plates. Applicable industries include automobile, construction, consumer goods, etc.
The seam welding method is characterized by continuous seam of welded material. Seam welding is suitable for various metals and thicknesses and is adopted by industries such as aerospace, construction and agriculture.
Another common resistance welding variation is butt welding. The butt welding process involves placing two components end-to-end and then welding along the join. Due to its simplicity, butt welding is adopted by various industries.
