WHAT IS THE BEST SHIELDING GAS FOR MIG WELDING?MIG welding with shielding gas and a solid wire electrode produces a clean, slag-free weld without the need to continually stop welding to replace the electrode, as in stick welding. Increased productivity and reduced clean-up are just two of the benefits possible with this process. The primary purpose of shielding gas is to prevent exposure of the molten weld pool to oxygen, nitrogen, and hydrogen contained in the atmosphere. The re …

THE DIFFERENCE BETWEEN METAL INERT GAS AND METAL ACTIVE GAS WELDING Welding is one of the joining processes that can efficiently and economically assemble two or more metallic or non-metallic parts permanently. With the extensive development throughout the years, a large number of such processes has evolved in order to cater the need to join a large variety of materials in innumerable ways. Gas metal arc welding (GMAW) is one such process where metallic materials are joined p …
