An electric arc supplies the energy needed for the arc processes MIG, MAG, TIG, and Plasma welding and cutting.
The frame and basic body components of a car, the joints in heavy steel constructions and in transportation systems are often joined using high productivity MIG/MAG welding. TIG welding, in contrast, is mainly used for material combinations and welding of thin components.
For joint preparations, plasma cutting is often used for a wide range of materials and material thickness, including low and high-alloyed steels and non-ferrous metals. Plasma welding is the preferred welding method when a high energy density is required, for instance in thick sections, but it can be used for thinner materials as well. Plasma welding is based on a principle that is similar to TIG, but with a higher energy density, due to a focused arc.
In all arc processes, the electrode, the molten pool and the heat-affected metal parts must be protected from reaction with the ambient air. Shielding gases play an important role in this protection. The shielding gas is added via the welding nozzle, protecting the electrode and the molten pool. Protection of the heat-affected metal parts and the root side requires additional protection devices. Protecting the weld is a primary function of the shielding gas, but protecting our welders and our environment is equally important. This is why Linde has developed several lines of shielding gas.
MISON® for example is a family of shielding gases for various welding applications. Each mixture has been developed for a specific type of welding application to bring you the very best results. Additives in MISON also significantly reduce ozone formation during welding, which can greatly improve the working environment. Whatever your base metal, filler metal or method, you can select from the MISON range to achieve higher deposition rates, improved weld characteristics and the right weld quality and appearance. |
