Double-sided welding welding preferred. Manual arc welding done, the weld on both sides of rust, grease, dirt, etc. cleaned, the weld into a metallic luster, in the welding process, should take effective measures, not to the wind, snow, ice, frost and rain erosion, when the work environ...
a地震发生在2008年当时我在上高中 The earthquake occurred in 2008 at that time I in on high school [translate] a从母材到焊缝中心其组织形态依次是带状组织、细晶区、粗晶区、柱状晶,组成相均为珠光体+铁素体,一次焊补未改变试样的显微组织。 From the parent metal to the welded joint center its ...
Welding consumable null in order to form the system which the weld metal the carbide does crystallization extensivelyPURPOSE:To execute welding without accumulating an oxide nor damaging a product by using specified welding material in case of the build-up welding of the metal product of a plate ...
The process of laser welding involves heating and melting the materials to be joined with a high-energy laser beam. The material is heated to the point of melting when the laser beam is concentrated onto the weld joint. The molten material solidifies along the path of the laser beam, creat...
