焊接是利用局部加热或加压等手段,使两个分离的金属形成一个整体的过程。它在建筑、机械、造船、国防等部门占有极其重要的地位。焊接工艺一般分为:熔化焊、压力焊、钎焊三大类。熔化焊又分为电焊、气焊、氩弧焊、等离子焊。目前以电焊、气焊应用最为广泛。
Welding is the use of local heating or pressure and other means, the two separate metals to form a whole process. It occupies an extremely important position in the construction, machinery, shipbuilding, defense and other departments. Welding process is generally divided into: melt welding, pressure welding, brazing three categories. Fusion welding is divided into welding, gas welding, argon arc welding, plasma welding. Currently welding, gas welding is the most widely used.
