introduction：shuixia qiege Underwater cutting underwater cutting The cutting of workpieces in water。Underwater cutting is mainly used in Marine rescue and nuclear contamination of structural parts in water disintegration。Underwater cutting can be divided into underwater thermal cutting according to the principle of cutting、Underwater explosive cutting and underwater mechanical cutting 3class。 Underwater thermal cutting is one of the most widely used cutting technologies for underwater construction，Accounts for approximately the total amount of underwater cutting90％above。Underwater thermal cutting methods are 4Kind of。①Flame cutting：Water flame cutting uses hydrogen as a flammable gas

introduction： Thermal cutting using laser beam as heat source﹐The working principle is similar to laser welding。Laser cutting temperature exceeds11000℃﹐Enough to vaporize any material﹐So in laser cutting﹐Apart from melting﹐Gasification also plays an important role。Some material(Such as carbon and certain ceramics)The laser cutting process is a pure gasification process。High power carbon dioxide continuous laser is used for laser cutting of metals。At cutting﹐Jet stream of inert gas﹐Blow off the cut to melt the metal﹐Can make the incision smooth and straight﹔The jet oxygen stream increases the cutting speed。Laser cuts have narrow incisions﹑

introduction： one）Meet the requirements of working conditions 1．Abrasion resistance When the blank is plastic denaturated in the mold cavity，It flows and slides along the surface of the cavity，Cause intense friction between the surface of the cavity and the billet，Resulting in the mold due to wear and tear failure。Therefore, the wear resistance of the material is the most basic mold、One of the most important properties。 Hardness is the main factor affecting wear resistance。In general，The higher the hardness of the mold parts，The less the wear，The better the wear resistance。In addition，The wear resistance also depends on the type of carbide in the material、quantity、form、Size and distribution are related。 1．Strength and toughness Working conditions of the mold
