   With the shielded metal arc welding and gas metal arc welding hardfacing processes, the life span of the ploughshare was increased approximately 2 times. [1] Extensive work in research has resulted in the development of a wide range of alloys and welding procedures. The optimum alloy selection is made considering the component service ...

4. Spot welding - Wikipedia

   en.wikipedia.org/wiki/Spot_welding

   The voltage needed for welding depends on the resistance of the material to be welded, the sheet thickness and desired size of the nugget. When welding a common combination like 1.0 + 1.0 mm sheet steel, the voltage between the electrodes is only about 1.5 V at the start of the weld but can fall as low as 1 V at the end of the weld.

5. Electric resistance welding - Wikipedia

   en.wikipedia.org/wiki/Electric_resistance_welding

   Spot welding is a resistance welding method used to join two or more overlapping metal sheets, studs, projections, electrical wiring hangers, some heat exchanger fins, and some tubing. Usually power sources and welding equipment are sized to the specific thickness and material being welded together.

6. Ferrocerium - Wikipedia

   en.wikipedia.org/wiki/Ferrocerium

   The idea that carbon steel is needed to produce sparks from a ferrocerium rod is an oft repeated myth. Though carbon steel does make the spark more prevalent when striking. [6] Ferrocerium is most commonly used to start Bunsen burners and oxyacetylene welding torches. [citation needed] About 700 tons were produced in 2000. [citation needed]
