Resistance welding is a very interesting field. There is no stop!!
It's just that most of the people underestimate it because of the lack of knowledge in this field.
With resistance welding you get a reliable & fast weld joint (provide all the weld parameters are correct), & this quality makes this process very suitable for mass production.
Resistance welding process is placed between fusion and solid phase process. It has Spot, Seam, Projection in one phase and Resistance butt, Flash butt, Stitch ,Series spot, Roller spot, Seam Welding, Butt seam, Foil butt-seam, High Frequency Resistance, Percussion in the second phase.
Mild steel, Stainless Steel, Alloy steels, Tool steels, Aluminum and its Alloys, Copper and its Alloys are being welded using Resistance Welding process. Both similar & dissimilar metals could be welded.
All fabrication units like Automotive - main body, brake drums, seating, front window panels, silencers, aircraft products, House hold applications, farm implements, telephone industries, Electrical Industries, rail coaches, bolts, nuts , paneling, wire drawing units, band saw welding - you name it - you will see some form /type of resistance welding.
It has wide application now a days and unavoidable in many fields as mentioned above. Its future is far better compared some other processes where it is static.
The job opportunities are unlimited and not to speak of subcontracting work for main manufacturers specially fast growing automobile industries.
