Types of Welding Machines Used for Residential and Industrial Purposes
Working with metal is both an exciting and a dangerous job. As the sparks fly from the superheated metal, welders are able to transform even the hardest of metals into the shapes they want.

3) Spot <strong>Welding</strong><br />
■<br />
■<br />
Spot welding is a resistance welding machine that specializes in joining 2 to 4 steel<br />
sheet with thickness <strong>of</strong> around 3 mm each. Along with machine, a pair <strong>of</strong> electrodes<br />
are used to bind the metal sheets together <strong>and</strong> pass current through them.<br />
Some great benefits <strong>of</strong> using this machine includes limited work piece de<strong>for</strong>mation,<br />
higher manufacturing rates, effective power use, no automation, etc. This is widely<br />
used in auto industry where cars can have several thous<strong>and</strong> spot welds. Spot<br />
welding is opted instead <strong>of</strong> expensive options such as mechanized fastening, <strong>for</strong><br />
e.g., screwing <strong>and</strong> riveting.
