Guangzhou city deep source machinery company welding project by Huang new engineers hold DM certification, directly on the ship) led by the elite team, with all kinds of welding equipment, specifically to undertake related engineering cast iron welding, carbon dioxide welding, argon arc welding, plasma welding etc.. Welding is the process of welding the workpiece interface to the molten state, without pressure to complete the welding process. When welding, the heat source rapidly melts and melts at the interface of the two workpiece to be welded to form a molten pool. The molten pool moves along with the heat source, and a continuous weld seam is formed after cooling, and the two workpieces are connected into a whole. In the process of welding, if the atmosphere is in direct contact with the molten pool at high temperature, oxygen in the atmosphere will oxidize metals and various alloying elements. The nitrogen and water vapor in the atmosphere enter the bath, and then, in the course of cooling, porosity, slag and cracks are formed in the weld, which deteriorates the quality and performance of the weld. In order to improve welding quality, various protection methods have been studied. For example, gas shielded arc welding is to use argon, carbon dioxide and other gases from the atmosphere, in order to protect the welding arc and weld pool rate; and as the steel welding, adding the oxygen affinity of large titanium powder in the electrode of oxygen, can protect the electrode in the beneficial elements of manganese and silicon from oxidation and enter the molten pool, after cooling to obtain high-quality we
