EPSTAL steel was tested at the Welding Institute in Gliwice. The aim of this study was to design and test welded joints with the MAG method and the welded resistors on the cross. The scope of the study included: static stretch test, shear test and bending test.
The positive results, described in the Welding Institute's report, show that all tested joints had good strength and plastic properties:
MIG/MAG welding (eng. Metal Inert Gas/Metal Active Gas) - MIG welding or active MAG welding. Protective gases are most commonly used argon, helium and mixtures of these gases. As active carbon dioxide or its mixture with argon. In the MIG / MAG method, the electric arc glows between the welded material and the electrode in the form of a wire. The arc and lagoon of liquid metal are protected by an inert or active gas stream. The method is suitable for welding most materials, selecting electrodes suitable for different metals.
Welding - a type of technology that permanently connects parts of devices or structures made of metal or plastic. It consists in heating the contact surfaces so that they become plastic and pressed them. Only a small volume at the interface is plasticized. Depending on the welding method used, pressure is applied first, then warming up, or vice versa, first heating and then pressing.
Resistance welding (electrical resistance) - is the most commonly used type of welding. It is divided into: face welding (spark), point welding (one and two-sided), linear (on the tab, linear-face) and projection welding. Electric resistance welding consists of 3 phases:
