The MIG process enables the home-hobbyist, artist, farmer/rancher, motorsports enthusiast or DIY welder to make most types of fabrication and maintenance/repair welds on material from 24-gauge up to 1/2-inch thick.See all results for this questionsp.info How is the heat produced in arc welding?There is no arc involved (except to start the weld), so the process is entirely different from submerged arc welding, and the electrical resistance of the metal being welded plays no part in producing the heat, Instead, the heat is derived from the passage of electrical current through a liquid slag.See all results for this question
- There are two methods of plasma-arc welding: a) Transferred-arc method - Work piece being welded is part of the electrical circuit. The arc transfers from the electrode to the work piece. b) Nontransferred method - The arc occurs between the electrode and the nozzle. The heat is carried to the workpiece by the plasma gas.See all results for this questionsp.info How long is the arc in Percussion welding?In percussion welding, the arc duration is only 1 to 10 ms. while the heat is intense, it is also highly concentrated.
