WELDING焊接
and
CUTTING打磨

WELDING is a process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the work pieces and a filler material to form a pool of molten material that cools to become a strong joint, but sometimes pressure is used in conjunction or by itself, to produce the weld.

焊接是通过普通金属的热聚合来连接材料的过程。一般通过溶解工件和填充材料来形成一个溶解材料填充池,通过冷却是它变成坚固的连接点,但是有时候也通过压力来造成连接,或者它自身来形成 焊缝。
DEFINITION 定义
COMMON TYPES OF WELDING 普通的 焊接
Oxy-Fuel welding 氧气燃料焊接
Metal fusion achieved by the use of high temperature flame produced by mixture of gases. 材料通过混合气体燃烧产生的高温火焰来产生连接
Manual Metal Arc (MMA) Welding手工技术电弧焊
Using flux coated electrodes which are replaced by the operator as they are consumed. No shielding medium is used in this Process.使用由操作手更换的带有外衣的可消耗的焊条,没有保护媒介物。
Metal Inert Gas (MIG) Welding金属惰性气体保护焊
Using a consumable wire electrode and a supply of inert gas.使用可消耗的金属焊条和惰性气体
Tungsten Inert Ga
